Making attachments for the engraver with your own hands. Engraver attachments. Home master's surgical kit. Homemade attachments for engraving machines and drills

"Dremel" (engraver, bur-machine, mini-drill etc.) is now a common noun.
Dremel is the name of a group of straight grinders designed for polishing, milling, drilling products (parts) from various materials and surface treatment.

It is desirable that the tool be equipped with a speed control system. The digital display, which allows you to visually control the speed, does not hurt at all. The ability to directly switch on the maximum speed increases the convenience of using the machine, eliminates the need for unnecessary operations. The flexible drive shaft guarantees comfortable and precise work in hard-to-reach places. The machine comes with attachments selected for basic operations - grinding, polishing, milling, cutting, drilling.

I will briefly try to tell you about these attachments (which are included in the kit and which are made from scrap materials) in this review.

Let's start from afar - with elementary safety rules when working with dremel :)

The first thing I highly recommend you to wear is safety glasses and protective petal mask... A medical bandage and even any flap of more or less dense tissue are quite suitable for this purpose. The mask will protect the respiratory tract from the imminent ingress of dust. Take my word for it, if you don't put on the mask, then by the end of the work with the dremel you can shake out a decent amount of rubbed copper or plastic from your nose.

Glasses are needed to protect the eyes from the same plastic dust and from metal debris / balls flying in different directions when grinding, for example, copper dendrites. I do not advise you to use glass goggles to protect your eyes. The glass can shatter, damaging the gas, or be scratched by flying debris. Don't skimp on glasses, get plastic ones made specifically to protect your eyes.
Further warnings will be issued in small portions as needed :)

So, nozzles.

Collets.
Drills, replaceable attachments for engraving, cutting, grinding and polishing are inserted and clamped into them:

Collets, most often, are supplied complete with a dremel and differ from each other in the diameter of the hole for nozzles and drills.

Drill.
To drill holes of different diameters, you need to have several different-sized drills on hand. And the larger the assortment, the better :) Drills become dull and break, especially thin ones (0.5, 07, 1 mm). The diameter of the hole usually corresponds exactly, and it is better if it is slightly larger than the diameter of a cord, pin, wire, chain or other type of threading material on which a bead or other decorative element will be fixed later. In this photo - reduced with a cross-sectional diameter of 0.5 to 2 mm:

* The workpiece must be held very tightly with your hands so that it cannot break out and fly off. The flight is uncontrollable in general, and the speed is colossal. The speed of rotation of the shaft in modern mini-grinders is from 9 thousand revolutions to 35 thousand. A bead that has escaped from your hands is quite capable of, for example, breaking a flower pot on the window, or a vase at the other end of the room, or, much worse, hitting in the face, if you nevertheless ... neglected the advice to protect it.

Never touch the rotating parts of the dremel (nozzles, drills, discs, collets) with your hands - you can seriously injure yourself.

As the hole is drilled, it will not be superfluous to use the drill to reciprocate in the bead. This allows the drilled plastic to clear the channel for further drilling. Otherwise, the bead runs the risk of splitting.

If, during the drilling process, the drill "got stuck" in the plastic, then it is better not to try to pull it out or drag it further along the hole. Switch off the dremel immediately and carefully pull out the drill.

Be careful when handling metal parts, you can burn your hand. The metal heats up quickly and strongly. Take breaks for at least a couple of seconds to keep the parts from overheating.

Metal brushes:

They are intended for processing metal surfaces. Differ in shape, density of bristles and rigidity, ultimately. In this case, we have steel, hard, brushes and brass, soft. In shape, brushes are flat disc-shaped, as in the top photos, and there are also brush-like shapes:

The choice of a brush is dictated by which surfaces are supposed to be processed - flat parts or textured surfaces, with a durable coating or with a thin foil-like one.

This photo shows plastic brushes:

These are soft brushes for gentle cleaning of metal surfaces in hard-to-reach areas. They are also suitable for more accurate sanding of surfaces with a thin weak coating (copper, for example).

* All of the above brushes (metal and plastic) are not suitable for grinding plastic - they are too hard for this.

Grinding stones.
This photo shows attachments for grinding and polishing metal and plastic surfaces.

In the top row (gray and orange) there are rough stone nozzles. They are only suitable for grinding serious roughness and are not suitable for delicate work and plastic work:

Homemade flat grinding attachment.
This series of photographs shows a DIY tool for sanding flat surfaces. I made such a nozzle on the basis of the stone that came with the Dremel, with a smooth flat surface (in the top row on the left - gray-green):

In hardware stores, circles are sold - "pancakes" with Velcro, for fixing hefty (15-16 centimeters) sanding discs made of emery:

These "pancakes" have a sticky layer on the back, smooth side. We cut out a circle from such a pancake, with a diameter of a stone round flat nozzle (photo above), peel off the protective layer, glue this circle to the grinding stone - and we get a nozzle for replaceable emery disks.

* You can use ordinary Velcro, sold in any sewing store, by placing it on the surface of the attachment stone with ordinary seconds glue.

Now about the removable disks themselves.
In the same hardware stores :), replaceable emery disks are also sold. The diameter of the discs is the same as that of the "sticky" - about 15-16 cm. On the one hand, they are ordinary emery (with varying degrees of granularity, according to numbers), and on the other, a counterpart for Velcro.

So, from these discs we cut many, many small circles (the diameter should be equal to the diameter of the Velcro, or a millimeter more, but not less!) And, as necessary - salting, we replace these self-made self-cut sanding discs with new ones:

Another view homemade nozzle for grinding and polishing round / oval beads.

In this photo - rivets:

These rivets are designed to be riveted with a special gun. The diameters of the technological "tails" of these rivets are different - it depends on the size of the rivet itself. I have it selected in such a way that it exactly matches the diameter of the toothpick on which the bead was baked.

An emery-sponge or the most ordinary emery of the desired grain size can serve as an image for grinding.

In this case, for example, an emery-sponge is taken (photo on the left). It is a soft material that does not allow the bead to be abraded too much when processed in this way.

A bead is put on the long "tail" of the rivet. The rivet tail is inserted into a collet of the corresponding diameter, the collet is fixed. Now you can turn on the dremel and grind the bead, as shown in this photo:

* A rivet with a "tail" is just an example of the fact that you can always find something at hand that easily adapts to a tool. The rivet in the description can be easily replaced with an ordinary nail of the required diameter, fixed in the collet so that the head holds the bead, and the sharp part goes into the collet.

Base nozzle.

Such a nozzle is necessary for fixing rough grinding discs-stones, cutting discs, soft polishing discs and felt nozzles with a through hole, as well as all kinds of homemade nozzles on its rod:

Further - several types of attachments, used much less often, but still necessary.

Felt polishing cones and discs.
They are used for finishing surfaces made of plastic and metal, but due to the fact that at high speeds such attachments "dust" mercilessly - there is absolutely no reason to use them.

In their image and likeness, it is quite possible to make home-made fabrics that will last much longer than ready-made felt ones and will much less litter the room with flying fibers.

Engraving attachments.

With the help of such nozzles, a drawing, an inscription, depressions, grooves, notches, etc., can be applied to a plastic and metal surface:

* In medical equipment stores, you can almost always buy diamond burs. Their assortment is very wide. The service life of such burs is quite long, and the accuracy of the work performed with their help is an order of magnitude higher than the standard engraving heads that are part of the Dremel.

Now about how you can get out of the situation if there is no dremel, and its purchase is not yet expected, and there is no longer the strength to manually grind / polish ...

Budget set for manicure can serve as a low-power sander for several months. This kit usually includes several attachments. In this set came across: a pair of grinding heads, a "pumice" metal and a flat felt nozzle.

Grinding heads (with metal cones of different diameters) and a flat metal one can be used without changes in design, but we modify the felt attachment in a barbaric way :) Rip off the felt, clean the plastic pad with coarse emery and, according to the same principle as described above, make a flat grinding attachment with removable disks. This is what we have after manipulating the manufacture of Velcro-emery:

With such a device, you can easily (but not very quickly) grind flat plastic surfaces, metal, wire, etc., which does not require high revolutions for high-quality surface treatment:

These are the pies.

Thank you for doing it :)

For processing small items, a micro drill is often used, which is called an engraver. With the help of an engraver, you can perform the same operations as with a conventional drill, as well as grinding and milling various materials. The frequency of use and the demand for a tool is determined by the quantity and quality of nozzles available to it. Some of them come with the main tool, but many have to be purchased additionally. Today, we will try to learn everything we can about engraver attachments.

Types of attachments for the engraver

The attachments for the engraver are selected depending on whether wood or metal is supposed to be processed with their help. For example, for woodwork you will need:

Polishing attachments - made of sandpaper or felt.
Ball-shaped nozzles for grooving.
Smooth attachments for the final sanding of wood surfaces.
Cut-off discs (can also be used for cutting plastic).
Drills for wood (usually small diameters, up to 3.2 mm).
Cutters (required to perform work at a professional level).

Engraver attachments for metal work include the same varieties as described above. The principal difference lies only in the material of the working surfaces. For example, grinding metal requires attachments made of more abrasive-resistant materials - corundum or hard rubber. The same applies to cutting discs, only in this case, tool steel of increased strength is used as a material (sometimes even - with a diamond-coated working surface). However, there are also specific types:

Diamond cutters, with the help of which the finishing of holes and cavities of complex configuration is carried out.
Coarse sanding attachments. They are supplied with notches, and can, in addition to metals, also process chipboard.
Tapered nozzles designed to produce grooves. Usually they are offered in a set, with different sizes of the width of their working part.
Brush-type attachments that are used to remove scale from the surface of steel products.
Carbide tips that can be used to create deep enough cavities in hardened steel workpieces.

The value of the attachments is determined by their versatility (many manufacturers offer similar products in sets), as well as by the manufacturer. It should be noted here that, as a rule, a company that produces engravers equips them with attachments that are suitable for their products, and it is not at all necessary that for competitors' products.

Purpose and capabilities

First of all, it should be emphasized that, due to its low power, a micro drill is incapable of performing any large-scale operations in metal or wood. Therefore, the dimensions of the tool, regardless of where it is produced, will not differ in large dimensions.

The defining moment is the diameter of the seat. For example, the diameter of the drill (like an attachment for an engraver) that can be used depends on the diameter of the chuck. The profile of the clamping part is important here. Manufacturers often implement the principle of point clamping, which simplifies the manufacture and adjustment of the micro drill chuck itself, but the performance of the nozzle deteriorates, especially if the processing process takes a long time. In this case, a beat of the drill appears, and since the number of revolutions of the engraver is high, the breakage of the nozzle will follow very quickly.

The second factor is the functionality of the size of the attachments. For example, for grinding work, there are a variety of attachments up to 7.8 mm in diameter (for woodworking) and up to 3.2 mm for metal operations. The diameter of cutting wheels can reach 19 ... 20 mm, but this corresponds to work with soft materials (plastic, aluminum, wood), and when working with steel, a drop in the speed of the micro drill motor will lead to its failure.

It is important to pay attention to the material of the instrument. In particular, attachments for the engraver, which are made of tungsten carbide-based hard alloys (VK8, VK15 and their foreign counterparts) are capable of working on heat-treated metal. They can also process glass, stone, mineral ceramics.

Finishing is the main area where industrial diamond engraver attachments are effectively used. Since their cost is very high, they go on sale in small sets (up to 10 ... 20 standard sizes). Diamond cutters should only be used for their intended purpose, otherwise the sprayed layer will be damaged very quickly, which will immediately lead to intense wear.

The most diverse class of abrasive and engraving tips. Their choice is usually made according to the color of the landing part. If it has a red color, then the nozzle is designed for working with metals, and highly resistant aluminum dioxide is used as the material. Green engraver attachments are effective for engraving work with fragile materials - glass, stone, marble, etc. Sets for such work include up to 10 sizes of attachments.

It was already mentioned above about the possible incompatibility of the diameters of the nozzles for the engraver with the diameter of the chuck of the tool itself. In addition, one should distinguish between professional and household sets. The former are more often produced by the German company Dremel, they are of high quality and price (experts note that the quality of the attachments that come with a micro drill is higher than that of the same company, but purchased separately). Domestic attachments for the engraver from the Zubr trade mark are not inferior in quality to the German ones, but differ in significantly lower cost. For comparison - the price of a Dremel attachment is 350 ... 400 rubles. per piece, and a set of more than 150 standard sizes from "Zubr" - only 1800 ... 2000 rubles.

We should also mention the attachments for the engraver made in China. The attractiveness of the price in this case is completely leveled by the low quality of the metal of the nozzles. This can be permissible only in those cases when the tool is rarely used, or the task is to learn how to work with attachments of a certain type.

The basic rules of work and the choice of attachments for the engraver relate, first of all, to the tool of the middle and budget price category and are as follows:

The choice of the diameter of the nozzles from a specific set should be carried out in accordance with their subsequent use;
For engraving, you can also use nozzles made in China, especially well they get diamond nozzles with a spherical head shape;
DIY tips are a great option for experienced DIYers. As a material, you can use plywood (it surpasses rubber in its durability), as well as felt, emery, etc. using an industrial nozzle. For polishing, diamond paste with grit 3/2 or 5/3 is most suitable .;
In any case, when using attachments, a respirator should be used, otherwise the dust generated during work will completely enter the lungs.

Some time ago I received a welcome gift - an engraver. Dremel 4000. The box was proudly labeled "65 accessories". In fact, about 20 of them turned out to be discs for cutting plastic, so the variety turned out to be not at all what it might seem. Considering the completely inhumane pricing policy of this manufacturer and its Russian dealers, I had to go online. Native attachments, taking into account the cost of delivery, were catching up with the option “go to Leroy and buy” at the price, besides, the assortment was upsetting. Therefore, I had to look towards China. There was a lot of interesting things.

Drilling

The kit included a 3.2 mm collet (and one more, which I have never used, because there is not a single nozzle for it in the kit). And a drill. The same 3.2 mm. But i.e. we seem to have a tool for fine work and a 3.2 mm drill is included. It is a pity that it is not a figure eight on concrete.

Jaw chuck 4486:

Drills 628 can be inserted into it:

Or use a set of wood drill bits for a 3.2 mm collet:

The design of the cartridge is not particularly successful. As I understand it, the drill is clamped pointwise, the area of the contact patch is small, the revolutions are high, there is a "bounce" of the drill. In addition, on the manufacturer's website there are a lot of reviews in the style of "out of curiosity, I completely screwed the chuck without a drill, and it no longer wants to spin back."

What do the Chinese offer?

For example, these are the sets:

Visually, bounce is invisible, brass drills perfectly. How many thousands of holes in a PCB can be made by one drill before it wears out - I don’t know, I haven’t tried it. But if you need to make several (dozen) different small holes - a great option.

I ordered on ebay from the seller sz_butterfly - they constantly have lots with a fixed price and regularly conduct auctions with a low starting price (and not 15 times the shipping cost). A plastic stand box was included.

Engraving

What are the regular stores?

Cutters. A bunch of cutters of various sizes and (sort of) purposes. A number of diamond tips. You can open the catalog or the manufacturer's website and look there.

Everything is great, if not for one but- price. For example, such a wonderful accessory Dremel 7105 (4.4 mm, shank 2.4 mm - the very second collet in the set) costs only 800 rubles for 2 pieces.

What do the Chinese offer?

To start with, I ordered a set of all kinds of diamond drills. Just to understand what I need. 180 rubles with delivery:

It turned out to be a great thing. you can draw thin (and not only) lines on metal and glass. Probably also in terms of plastic. Something like this:

IMPORTANT!!! When working, it is imperative to use respiratory protection. I used a regular gauze bandage and constantly wiped the product with a wet cloth. During operation, quite a lot of very fine dust is formed. I doubt that the lungs will be delighted with such a gift.

In my work, I really liked the spherical shape of the nozzle, because it is easiest for it to maintain good working accuracy. Therefore, I found myself the following sets of Diamond Round Ball Burr Bit Set:

Or these (300 rubles, free shipping):

Haven't ordered yet. I don’t know why I’m dull.

Literally a month ago, the choice was just that - either you buy native Dremel consumables for 500-1000 rubles per item, or you order from the Chinese. And 2-3 weeks ago, budget consumables for the engraver (for example, mini-sets of diamond drills) appeared in Leroy (I have it near the office, we regularly go there to look for something tasty). So the meaning of waiting for delivery has dropped somewhat.

Offtopic: In addition, there just as suddenly appeared canvases to what the English-speaking Internet calls the oscillating tool, but we call it whatever you like, right down to the electric broom

Hope this post helps someone try something out with their own hands. This is an interesting process.

Offtopic 2: I also faced the problem of finding metal for work. Brass was needed. In Moscow, a bunch of factories are ready to sell wonderful strips or sheets of brass. From 5000 rubles. It is desirable for a legal entity. from 10 to 17 hours. As a result, on the second try I bought what I needed at the non-ferrous metal collection point.

Greetings dear readers! How nice it is when a person has his own hobby, I am happy for these people and I find them interesting and fulfilling. I also like to do something in my spare time. But I rate my skills between a C and a C. Either you want to carve a carved bench into a bathhouse, or a stool from an array to a garage. It seems like an unnecessary craft, but the soul is resting. For this, a familiar carpentry tool is used. And when it comes to small local crafts, be it sculpture, engraving, carving, polishing. Dremel becomes indispensable here. When I was asked to review the dremel that had already appeared on the pages of Muska, I agreed, because the truth does not fade from repetition. Under the cut there will be disassembly and examples of use and attention, a lot of photos !!!

Packaging and equipment

Dremel comes in its original packaging, on which the tool itself is painted and some promotional information.

The main characteristics are drawn on the side of the box.

On the other side of the box is the same print

From the second side there is a description of the accessories.

Above, only the manufacturer's name is large

The box contains a set of 30 different abrasive tips.

The set is closed with a plastic transparent lid, each nozzle sits in its seat

Here's a closer look at the nozzles. Everyone will find a suitable one.

The length of each nozzle is about 45 mm

The set includes a convenient nozzle for vertical milling, with adjustable immersion distance into the material.

We gave us safety glasses as a gift.

And then, in a bag in bulk, they put a lot of tools for a home craftsman
Here is all this scattering

Cutting discs

Different collet sizes, Spare brushes

Felt polishing discs and original attachment + special attachment for attaching discs

Large set of emery wheels in two sizes and special attachments for them

The set includes 2 keys for tightening the nozzles in the chuck

Attachment for setting cut-off wheels.

Brush attachments

Various cones options

2 drills

The most enjoyable accessory for me is the flexible shaft.

It allows you to work without straining, just holding it like a pen.

Appearance
Dremel Made in bright red color.

The sticker shows the model.

There is a special black skirt in order to comfortably hold the dremel tip

Here is the Specification Sticker. Dremel has a power of 180W and develops up to 30,000 rpm.

- Here is the speed controller

There is a special bracket for hanging the dremel when working with a flexible shaft

Metal "button" for tightening the nozzles in the cartridge.

European plug

To replace the brushes, you don't have to disassemble the dremel, there are special 2 compartments for their hot replacement, you just need to screw 2 covers on the sides

Disassembly

Exploitation

In order to show the "abilities" of a dremel, you can come up with a lot of scenarios.
I have 2 cats “on the farm”, more precisely a cat and a cat, since we live in the private sector, they are left to themselves and walk in free self-walking. If the cat is not yet very active, then the cat is a real CAT. It may take a week, come thin but happy. And so that during these reckless times his mistress does not add gray hair, he decided to try to make a plate on the collar on which the nickname and our phone would be written, if someone finds this beast, when he goes crazy with hormones and cannot return home, they will call "his family." In general, there was already an attempt at such plates, I ordered from an advertising agency, made of plastic and swore that it was of high quality ...
Like these ones

But in fact, they served no more than a week and were lost, gnawed.

I took out very high quality stainless steel strips, 1mm thick.

But the trouble is, I tried to drill a hole, and ... I failed, 5 killed drills, different manufacturers and 0 effect. I thought that here, too, a fiasco awaits me. But the dremel made me happy.
I loaded the cut-off wheel, and let's cut :)

Sawed out an approximate shape

Ennobled a little

On the other side

I took out the engraving attachments from the set and began to try my hand ...

Oh, and this is painstaking work ...
It can be seen that it is clumsy, but this is a test sample.
It remains to drill a hole for the collar ring.
It is simply unrealistic to do it with a drill, so at first I shot one at a time with a small cutter. And then, when a tiny hole was already visible, he "finished off" with a drill. As a result, the drill is killed :)

But the result was achieved, albeit ugly, but the result.

Here is the disc after all the work, you can see that once I freaked out and pulled sharply, the triangle broke off from the disc ... in general, ghxyst discs do an excellent job with such durable stainless steel, with hardened self-tapping screws, but fragile in this direction.

Then I decided to "grind" the surface a little, the nozzle with the sandpaper did an excellent job with this.

Then he refined a little with a cone

Neat engraving of the number on the back took a lot of work, but it didn't work out to hang the craft on the cat, he's gone for half a week already ...
After such work, here is the state of the cutting disc.
It was

Has become

Then he made a small plywood table. But there were no suitable screws, they were slightly longer than the thickness of the plywood. It was too lazy to go to the store, the table was not for the exhibition, to help myself.

In the end it looked like this

there is nothing pleasant here, you can easily injure your hand ...
so a couple of light strokes with a dremel with a cutting disc and voila.

Maybe the photo does not convey, but by touch there is no feeling that something is sticking out. Everything is smooth. A self-tapping screw cuts such a disk in seconds, with a fountain of splashes.

And I considered the third option for purely domestic use. The son has a "railway". In fact, it is plastic, and in the semaphore zone, the son broke off the plastic lever for stopping the train "on red", it just did not work to glue it ...
The photo was not there, screenshots from the video, so I hid it under the spoiler

There are just a huge number of different tools on sale that can be used for machining parts. An example would be an engraver. In many ways, this tool is similar in its principle of operation to a drill or grinder, but it is designed to work with small-sized workpieces. By purchasing and installing various attachments for the engraver, you can carry out grinding, milling or engraving, as well as drilling. It is important to choose the most suitable options for the execution of nozzles, since they are characterized by different performance characteristics and areas of application.

Features of attachments

Wood drill bits can be classified according to a fairly large number of different characteristics. There is a wide variety on the market. Almost all equipment for an engraver is characterized by the presence of two structural elements:

The shank is a part of the nozzle for the engraver, due to which it is fastened in the chuck of the equipment used.
The working part is responsible for the direct removal of the metal layer at the time of processing.

Metal engraving paste is used to significantly increase the efficiency of the processing, especially if the tool for the engraver is intended for surface grinding. The description of nozzles can be distributed by manufacturers, since the cutting edge of some versions can have complex geometry.

Tooling for an engraver can have a huge number of distinctive features. Drill bits and other types of equipment can be classified according to the following criteria:

The type of material being processed.
Appointment of the drill and the used engraver's attachment.
Areas of use.

An example is diamond cutters for an engraver, which can be used for end surface machining and complex surface shapes.

The use of hard spraying can significantly extend the service life of the cutting edge, as well as provide higher cutting data. A mini drill for a drill is used to obtain blind or through holes with a minimum diameter value. The main classification can be called what technological task a nozzle for an engraver is purchased for. By providing a variety of this indicator, the scope of the engraver is significantly expanded.

By type of processed material

When choosing the most suitable kit, attention is paid to what kind of materials it is designed to work with. The classification of instruments in this case is as follows:

Most of the options are designed for working with wood. An example is the fact that the engraving cutter for wood has become widespread. It can be used to create a variety of patterns. Provides high processing accuracy if necessary.
An engraver is used with appropriate attachments for working with metal. In this case, when manufacturing the cutting edge, more wear-resistant and hard alloys are tried on. When choosing a tooling, it is important to pay attention to which alloy will be processed. An example is the ratio of the hardness of aluminum to hardened steel.
Glass accessories are quite often purchased. This material is difficult to machine. That is why the cutting part is often made of wear-resistant alloys or diamond chips.
There are engraver attachments that are designed to work with stone. The diamond cutter for stone has become quite widespread. The high hardness of the machined surface means that special requirements are imposed on the cutting edge.

The purpose of the type of material to be processed largely determines the cost of the tooling. The most affordable offer is considered to be wood cutters, which are very widespread. Versions designed for working with metals are also often found.

By appointment

A tool for engraving on metal or wood can be used for a wide variety of operations. On this basis, the following design options are distinguished:

For engraving work. Very often it is necessary to apply some kind of drawing or inscription on the surface. If the work is carried out in a home workshop, then the engraver can be considered a more suitable tool. There is an engraving cutter for metal or wood, artificial or natural stone, glass and other materials. Diamond burs (cutters) are often sold as a set, as complex designs and inscriptions may require bits with different cutting edge geometries.
Tools with a combination of a solid metal rod and an abrasive tip. In some cases, it is necessary to finish the quality of the roughness of grooves or other complex surfaces. In such cases, just such a rig is used. Its purpose is to rough and finish the surface, it all depends on the grain size of the abrasive material used.
For grinding and polishing. On sale you can find just a huge assortment of grinding attachments for the engraver. Various materials can be used in their manufacture. An example is a classic abrasive or felt.

When choosing, it should be borne in mind that for the engraving and other nozzles of the engraver intended for grinding the surface, there are a variety of pastes. Their use can significantly increase the efficiency of the operation. The selection of the paste is carried out in accordance with what kind of tool is used for processing and from what material the part was made. Before using any paste, attention should be paid to the instructions for use.

Considering the classification, we will also pay attention to the fact that there are working attachments for professional engravers. They are intended for a multifunctional tool that can be used for a wide variety of operations. The most common set of such equipment is represented by the following combination:

Cutters that come in a variety of shapes and sizes.
Cutters made of abrasive, felt or diamond spraying.
Drills that transform a conventional engraving machine into an efficient drill for precision drilling work.
Wire attachments that can be used to clean the surface.
Cutting discs designed to remove part of the product.

If desired, the kit can be assembled by purchasing all attachments separately. However, some versions are extremely rare on sale, which makes it difficult to purchase them separately. An example is cutting discs.

The set of attachments for the engraver is produced under various brands. As noted earlier, with frequent processing of workpieces with the tool in question, a sufficiently large set of nozzles is required. The following factors can influence the choice:

What kind of technological tasks will have to be performed. As noted earlier, the drill can be used to carry out just a huge number of technological tasks: engraving, surface grinding, cutting, drilling and others. The choice is made in accordance with what kind of work will be carried out. There are universal kits on sale, represented by a combination of nozzles of the most different types.
Characteristics, geometric features of the workpiece and the type of material used in the manufacture.
Estimated dimensions of the workpieces. Too small a tool is not convenient to handle larger workpieces. At the same time, it may take much longer to achieve the set goals.

A set of cones and other nozzles can be minimal or include several tens of units. In this case, the choice depends on the budget allocated for the purchase of equipment and how often the work will be carried out.

When choosing, attention is also paid to the classification according to the purpose of the sets:

Professional level. The high cost of such an offer is primarily associated with a long service life and exceptional performance. In addition, the cutting part retains its shape over a long period, which ensures the accuracy of processing. It is advisable to choose such equipment only with frequent carrying out of the corresponding work.
Budget proposals. This group can be conditionally divided simply into a huge number of categories. The most affordable tool will be an offer from Chinese manufacturers, but it will not last long and often does not correspond to the declared characteristics. Some well-known manufacturers are also engaged in the production of instruments of this class, but at the same time they maintain a fairly high level of quality. That is why, in case of rare work, attention should be paid to just such a proposal.

When buying a tool, you can view it. There should be no obvious mechanical defects on the surface. In addition, much attention is paid to symmetry, which is difficult to verify without special equipment.

Making nozzles with your own hands

For some surfaces on the market, it is difficult to find a more suitable tip. That is why many are considering the possibility of making them with their own hands. An example is wood cutters for dremel, which are also quite widespread today.

In a home workshop, you can make a cutting disc or a grinding head. A primitive cutter is represented by a corrugated cylinder from a conventional lighter. The sanding attachment is made from a wooden drum, to which sandpaper with the required grit index is attached.

Do-it-yourself nozzles for the engraver are made due to the fact that they can replace completely purchased versions. However, do-it-yourself woodcarving nozzles are very difficult to make. This is due to the fact that the working part of such a tool has a complex geometry, which can only be repeated by a real professional using special equipment.

When making your own equipment, you should pay attention to the features of the fastening. A corresponding element from a broken tool can be used as a shank.
