Manual saw on raw tree. What better to choose a tree with a tree. By the size of the teeth

Manual hacksaw, at first glance, a fairly simple tool that does not require much maintenance. Nevertheless, few people know about the criteria for choosing a saw and its views. Like other tools - manual hacksaw has certain signs of quality and characteristics.

The main parameters of the hand tool for cutting wood

Hoven is one of the most required tools In the inventory of every man. This device allows you to easily change the size of wood and plastic lumber. With the help of a hacksaw, you can produce a lot of operations in construction, to cut the branches in the garden, shorten the thrills of hedge and so on.

Manual hacksaw apply to working with sawn timber

But when buying this, at first glance, a simple tool is far from all thinking about how to make a choice and what criteria should be considered. Hoven has its own specific parameters that may affect the quality of work. There are four basic parameters when choosing a hacksaw: the length of the canvas, the value of the tooth, the type of steel and the type of handle.

Length of the web

For the convenience of operation, the length of the blade of the knife is chosen so that it is twice as far as the material size in the cut scene. This makes it possible to effectively extract sawdust while working due to the fact that all the tooths of the canvase will leave the board / log. In addition, the ratio of the size of the hacksaw and lumber contributes to a greater scope of the movement of the hand. This, in turn, takes away much less forces. In construction, the versatile knife with a length of 45-50 centimeters is most often used. To work with small bars and boards, there will be a cloth with a length of 30-35 centimeters.

The magnitude of the teeth

This is perhaps the most important parameter. After all, it is precisely from the size of the tooth that the speed and accuracy of the cut depends. The number of teeth on an inch of the canvas is taken to indicate the TPI coefficient. For more accurate work with the material, it is necessary to use hacksaw with a large TPI coefficient, that is, with large quantity teeth. When choosing a cloth with TPI at least 7-9, and the distance between the teeth is no more than 2-4 mm, the surface in the place of cutting will be more even and without ripped edges. For work S. large bars and garden trees It will serve as a canvas with TPI 3-6, the distance between the teeth over 4 mm. The use of such a hacksaw will reduce the efforts spent and increase the speed of cutting the working material.

Sharpening teeth

The usual triangular shape of the teeth of the hacksaw is adopted for the standard. The teeth are performed in the form of an acute-angled triangle or an equifiable, depending on the destination of the cut. Such a canvas with a special ease can be sharpened, repeating all the corners of the teeth. You can use such a canvas both for the longitudinal and transverse cut into avoidance of coarse jar.

The teeth of the classic hacksaw are made in the form of a triangle and sharpening

But modern hacksaws, in contrast to the classic, have a canoe teeth with a non-standard trapezoidal form. Such saws are endowed with high strength and resistant to wear. Their steel will not succumb to sharpening, and all the angles of the stuffed teeth are very difficult to observe.

Modern hacksaws are made with waters of the trapezoid

Type of steel

For the production of knobs of hacks, most often used stainless steel High grade. Usually wood saws are made from steel HRC45 hardness. Very often manufacturers combine steel in the canvas. In the hacksaw with the combined web, most is also made of steel 45, and here cutting part from steel 55 and 60. When hardening the cutting edge rises wear resistance. This type of tool can be easily distinguished from ordinary knobs on dark coal teeth.

The first forged saws did in ancient Greece. Forging gave a high metal hardness and increased the quality of the tool.

Type of handle

The convenience of its operation depends on the right choice of handle saw. Handles made of wood or plastic. Highly important moment - The surface in the place of grip should be such that the hand does not slip. This is eliminated by performing on the handle of scars, or coating it with a rubber layer. The hacksaw can be both classic cast and with a cross-blade. The latter allows you to replace the canvas, which is very convenient.

How to choose a manual hacksaw

Combining all the basic parameters of the saw, each can easily decide for himself, which he fits more. When choosing a tool, it is necessary to decide for yourself, which saw is more suitable - carpentry or carpentry. If most importantly, the speed of cutting, then, undoubtedly, you need to purchase a carpentry. In carpentry hacksaw, a smaller amount of teeth inch, which contributes to fast performance and removal of sawdust. If in priority the accuracy of cutting, then you should use the joiner.

The quality of the hacksaw can determine simple ways. First, it is necessary to visually make sure that the canvases are evenly accurate. Then you need to bend with a little effort to bend the cloth and release as soon as the resistance appears. After the blade wins and calm down, the smoothness of the canvas should again view. If it is slightly rejected from the initial position, then the tool is not recommended to buy it.

If you need a saw for a longitudinal cut, you need to choose a hacksaw with a sharp corner of the teeth. The teeth in such saws are sharpened only on the one hand, so the cut will be made only in one direction - from itself.

Teeth canvas for longitudinal sawing sharpened in the form of an acute-coronal triangle

With a longitudinal sawmill, the saws occurs in parallel with the fibers of the material. For longitudinal sawmills, the filtering hacksaws and the lyric saws are well suited.

Handsaws for transverse cuts are the most common. They have a teeth are made in the form of an equilibrium triangle and are sharpened on both sides. This allows you to cut in both directions..

For cross-cutting of the teeth, the blades are made in the form of an equilibrium triangle and sharpened on both sides

In case of cross-saw, the saws are carried out across the fibers. For such sawing, classic hacksaws are suitable, with a backrest, and with a large thickness of the material - two-handed saws.

The price of saws is also an equally significant factor when choosing. More expensive hacksaw gives a guarantee of reliability and resistance to wear. Those saws whose price is significantly lower than the average, made of cheaper raw materials and do not guarantee you long-term service.

What types of manual saws which application suggests

Classic hacksaw is the most common of all. It has a long and wide cloth. If the cloth is too long, when cutting, the hacksaw can be deflected aside. It is necessary to show high attention to avoid the deviation of the line cut from the initial markup. Such a hacksaw is suitable for working with a timber, boards, chipboard and so on.
Hacksaw with a back. This saw model has a hard rib-nozzle, which minimizes the frequency of canvas oscillations. And also in such a hacksaw smaller teeth and a larger TPI coefficient. They are designed to cut plywood, chipboard with a layer of coating and sawing profile planks.
Clean sawing saws have a reckless handle. They are needed for feeding grooves, grooves and sawing straight and profile planks.
Removable hacksaw, or knife with a narrow web. It also applies to dug grooves, as well as to dry out parts with rounded places and large holes.
Basic saws well will fit both for cutting of bitch and coarse parts of the material, and for drinking parts from plywood and wood. Such a hacksaw is characterized by a thin cannol, fixed on both sides in the frame. It is worth noting that it is necessary to work with it extremely gently due to its increased fragility.
Award - has two handles. The appearance of such a saw is largely similar to the plane. It is used for the cutting of spikes and grooves, deepening holes and slots in materials of any hardness.
Garden saw with curved blade. Most often, for greater convenience, they are made folding. Such a saw fit well to work in the garden. The saw blade is made of chromium steel. Widely spaced teeth with a slope in the direction of the handle will allow convenient to cut the bits and branches, making the focus during the cut.
Two-handed saw has the greatest performance. It has two wooden handles. It is necessary to produce such a saw for greater efficiency together. Two-handed saw is often used to saw large logs and trees.
Manual or pocket chain saw - is a small piece of chain with two handles at the ends. Such a saw is convenient to work both in one and together. A closed or bitch is wrapped with a chain and with the help of the handles it can be cut. Manual chain saw, as the folding, it will be good for working in the garden.

Such a classic hacksaw with ease can be sharpening. This hacksaw has a shovel teeth and an increased wear resistance of a hacksaw with a back, or a volatory minimizes the fluctuations of the web during operation of the knife with a narrow web fit well for the cutting holes and grooves.
Such a saw has a stopper handle, which will work at the right angle. Bind-like saws well fit for drinking parts from plywood. This type of hacksaw is similar to the plane and applies to the cuts of spikes and slots two-handed saws suitable for cutting large logs.
Garden saws with a curved blade are well suited for the spill of bitch and small branches of trees
Manual chain saw compact and good suitable for having a manpiered hike and branches in the garden

Thus, carefully studied all the nuances regarding the hand-hacks, everyone can choose for themselves the most suitable option. The right choice of the tool will provide you with high-quality and pleasant work.

A tree, as a building material, is distinguished by numerous advantages, not the last of which is simplicity of processing. Various tools are produced to work with wood, but the simplest and common hand-made hand-hacksaw remains the easiest and most common. What parameters are the tree knife, what is better and what to pay attention to when choosing a new tool?

Criteria for choosing a tree hacksaw

The choice is pleased convenient optionAs a rule, is determined by the following characteristics:

length of the canvas;
used in the production of saws material;
configuration of handles;
shape, step, tooth sizes.

Even with a change in one of the listed characteristics, the operational properties of the hacksaws are also noticeably changed. It is clear that the shape of the handle affects the comfort of working with the tool. Therefore, if you use a saw predominantly one master, you need to pick up the handle so that, as they say, "lay down" in hand. If you use hacksaw rarely, and not too intense, then the comfort comfort becomes not the most an important parameter.
Most often hacksaws with a length of the canvas from 350 to 600 mm. The selection of the length of the canvas depends on the intended thickness wooden productswho have to saw. Here the main thing is not to fall in extremes, because too short web will have to work longer to achieve the same result, and too long canvas, especially when sawing solid wood, can spring and, again, create difficulties.

Material of the canvas, step and tooth types

Material for the production of beans of hacksaws is usually instrumental or alloy steel. In order for the tool to serve for a long time, you should choose a saw with a web from high types of steel, better - from a stainless steel. The price will be higher, but it will probably pay off. In addition, the teeth can be tempered or not. Both options have their own advantages. Unkredited teeth can always be molded, with a certain skill. Calee teeth are more reliable, serve longer, but sharpening them after they wear out, it is unlikely to succeed.

To the question of what kind of tree knife is better suitable for certain conditions, most often you can answer, based on the size, view, the tender step. Effective cut wood materials It is characterized by speed and accuracy of the cut. These properties depend on each other - the accuracy of the cut guarantees a small tooth, while reducing the speed of operation. Larger teeth accelerate sawing, but the quality of the cutting surface and accuracy becomes worse.

For the correct selection, the TPI parameter is important, which means the number of teeth on an inch of the working length of the canvas. This coefficient is usually listed in the labeling on the side surface of the canvas. For neat operation, where the accuracy and quality of surfaces are of a serious meaning, TPI should be 7-11, if the speed is preferable, the TPI is selected with the value of 3-5.

By type of teeth, several types of hacksaws are distinguished:

For longitudinal sawing. This tool has a teeth in the form of a rowing triangle, is used for sawing wood along the fibers.
The transverse knife is equipped with an equally chained triangular teeth, mainly used for dry wood.
For mixed sawing. Triangular teeth alternate with semicircular. Not recommended for intensive, frequent use.
With a trapezoid tooth. Each tooth of this hacksaw has three cutting edges. The use of this hacksaw has indisputable advantages - the tool saws quickly, effortlessly.
The modernized saw has grouped teeth, separated by special intervals that make it easier to remove the chips from the cut zone.

Hackes, except for the shape and location of the teeth, are separated in the form and length of the canvas, are folding, with different shapes of the handle. On durability, as well as the quality of the instrument, can indirectly indicate the price. A good hacksaw is unlikely to be the cheapest.

Popular models

Information of sellers about which tree hacksaws are best sold, makes it possible to judge the most popular models. Consider some of them.

The hacksaw or how else is called it, the wood saw refers to the tool that should be in every house and even more so at each dacha. But the choice of hacksaws on a tree is not as simple as it seems to be in detail the types of tool in detail, you will learn about the configuration and appointment of various kinds of teeth, "we will walk" according to famous brands, and finally, I will tell you what kind of saber electric woodcutter and How to choose it.

Technical characteristics of manual tools

The hand-hacksaw on the tree has several fundamental parameters - this is the brand of steel, the length of the canvas, the shape of the canvas and the tilt of the handle, but the most important parameter is the form and type of tooth, and this characteristic is the same for both manual and electrical models.

The quality of domestic hacksaws on a tree is not inferior to foreign analogues

The length of the hacker canvas

Here it all depends on what purpose the knob is bought. So if you take a hacksaw in city apartment And do not plan it to work constantly, then a sufficiently folding model with a length of the band 300 - 400 mm is quite enough. For a private house or cottage, a full-size tool with a cloth 500 is 700mm is already needed.

Important! When cutting blank length, the length of the web should exceed the thickness of the workpiece at least twice as well, otherwise the sawdust will accumulate inside the cut and the hacksaw quickly cries.

For one-time work, folding or small-sized types of tree hacks are suitable

Brand steel for tree hacksaw

In the recent past, the knobs were made from the brands of HRC45 and HRC50, the metal is high quality, but the canvas requires periodic sharpening. Now all the leading manufacturers produce hacksaws with combined canvases.

The canvas itself is made of steel HRC45, which provides him with good flexibility and high strength, and the cutting edge with teeth is made from steel HRRs55 or HRC60. You can learn such hacks in the dark cutting edge.

Important! When buying hacksaws with a dark edge of high strength steel, make sure that it is already diluted and sharpened. The fact is that the sharpening and wiring of the lover of such a metal at home is very problematic, accordingly, it will be necessary to additionally pay for cloth sharpening.

Handsaws on a tree with a dark cutting edge differ high quality

Tooth selection for tree hacksaw

Before dealing with the configuration of the tooth, let's talk about the labeling and the magnitude of the teeth. Any kind of wood hacksaws are classified according to the same parameters. The marking indicates the number of teeth of 1 inch (1` \u003d 25.4 mm) and denotes this indicator as TPI.

TPI indicator talks about the number of teeth for 1 inch of the canvas

Drawing on a tree with a small tooth has a TPI from 7 and higher. And the more the number of TPI, the more accurate and cleaner will be cut, but at the same time, the speed of operation has dropped by such a tool in proportion to the increase in TPI, simply speaking, a small tooth cuts exactly, purely, but long;
Handsman on a tree with a large tooth has a TPI from 1, to 7. This tool is designed to work on garden and dumart sitesIn other words, a large tooth is taken to cut firewood or cut the branches.

The higher in the marking, the TPI indicator, the cleaner and there will be a sharper

There is a commodity expression "medium tooth", so in the documents the value of the TPI of the middle tooth is not recorded anywhere, but in the people to this direction include hacksaws with TPI from 5, to 8.

The step of the tooth is not the only parameter when choosing a hacksaw

Tooth diagram of knife	Explanation
	. Made in the form of an anose-free triangle, sharpening is made on both sides.
	. Here, the triangle is bevered toward the saw and the cutting edge of the tooth becomes perpendicular to the wood. Sharpening is performed only with a working (perpendicular) side, as a result, the tooth is combined into an array as chisel. Designed for the dissolution of the tree along the fibers.
	. An excellent solution if you buy a hacksaw "for all cases in life." The triangular tooth is slightly bevelled in the direction of the cut, while the sharpening is made on both sides of the tooth. As a result, with a cut along the cloth, the tooth works as chisel, and the reverse sharpening also allows you to effectively cut the tree across the fibers.
	. This sharpening is sometimes called triangular, but in reality it is not. Quinge tooth takes the basis of the basis, but sometimes the universal is also hurned. The top of the triangle is slightly cut at an angle and is additionally sharpened. This approach allows you to work with a tree in any direction and at any angle.
	. A complex sharpening allows you to do without a wiring of the tooth, but only a professional can perform it. The triangular tooth is sharpened on both sides and bevelled in the direction of the handle, plus the top is cut and also sharpened. When working with a hacksaw, there is only during the movement of the instrument to the employee. The first of this technology was used by the Japanese, so the name was taken from there.
	. Here there are several types of tooth on the canvas, but the essence of the wolf tooth is in the presence of skips between sectors. It is intended for such a cutting knitting and raw wood cutting, so the model is shorter than half a meter. Important! In addition to the configuration of the depicted on the left, there are still several circuits of hacksaws with skipping between the teeth, they are called differently, but the purpose is one everywhere - cut the crude wood.

How to choose a tree hacksaw

What is a saber saw and how to choose it

Now let's figure out how to choose an electronics on a tree, in the language of professionals such a tool is called a saber saw. Compared to the hand tool, the selection criteria here are a bit different. So in addition to the reciprocating movement, the saber saw also has a pendulum move.

To trim the trees with a saber saw on the instrument there is a pendulum mode of operation

The fluctuations of the canvas on the principle of the pendulum make it much more efficient to work, for example, when trimming trees or other draft work. And the standard mode is good when placing sheets of different density.

In this case, the question of which tree hacksaw is better not entirely correct, because in the saber saws, the effectiveness of the tool depends on the right choice of the blade. There are blades designed to work on wood, metal, stone, plasterboard, etc.

Each replaceable saber saw blade is designed to work with a certain material.

But the selection of a saber saw does not end only on the purchase of high-quality cloth under the appropriate material, there are still a number of subtleties:

I, like most masters in this area, believe that buying an electronics with a capacity of up to 600 W is just in vain the money spent. It can cut twigs up to 20 mm in diameter and no more. From 600 W, up to 1 kW suitable for diverse dacha work, and a tool with a capacity of 1.2 kW is already related to the semi-professional and they can be effectively cutting any materials;
It is advisable to choose a model where a special key is not needed for changing the web;
It is better to take a tool with a cut depth limiter, which, by the way, can also be regulated by a key and without a key, respectively, the second type of hacksaws is more convenient;
Pay attention to the head holding the blade. There are universal models in which any canvas are inserted, and there are heads "sharpened" only under the branded canvases of this manufacturer. It's not a fact that the store will be the right model of the corporate canvase, so take a wagon;
Theoretically, all saber saws have the ability to disconnect the pendulum turn, but it is advisable to check how adequately this option is working;
Sabel saw with a speed regulator will significantly expand your ability to work, and it is desirable that this regulator has a function of fine tuning;
Another useful feature is the possibility of turning the blade at different angles, such an option is especially useful when working on the ceiling and in hard-to-reach, close metas;

Sabelnaya saw with a battery, compared to network models, has a smaller power, but it is more convenient to work

Output

Relying on the data above the recommendation and video in this article, the competent choice of tree hacksaws for you will be much easier and note that the money spent is not the worst, not quality instrument Take a lot of time and strength, and most importantly, such hacksaws can be dangerous. If there is a desire to add something to what has been said or remained, welcome to the comments, let's talk.

Each real wizard (even at home) has always convenient and multifunctional disc electronized. But sometimes there are such types of work when you need to sprinkle only one item, or simply perform small amounts of work, and get electric device I do not want. In this case, the hacksaw blade will help you. But how to choose good knife A tree that will be comfortable in work and easily "strips" any breed of wood, we will look further.

On the right it is the saw that you can call the mother of all hand tools. From the moment people understood the importance of iron and created the first saw, the tool changed many times and already has a dozen "sisters", which can be performed any type of work.

Let us consider in more detail what each of these parameters should be.

Hacksaw blade - what it should be

The main part of the tool is the canvas. The first thing to pay attention to when choosing a tree hacksaw is the length of the canvas. From this will depend a lot, even even possibility when applying.

At the same time, than the cloth is more, the stronger it will spring, which will complicate the process, especially when working with maple, ash and oak.

If you are planning to cut bars, or narrow rails, you have enough tool length from 25 to 30 cm. When using the tool for serious work in construction, give preference to tools with a length of the web 50 cm.

When the length is selected, it is necessary to be guided by the rule that the length should exceed the diameter of the element processed by exactly 2 times.

If you do not comply with this recommendation, you complicate your work. The short-hack teeth will only eat in the wood, and move such a saw to free it from sawdust, it will be very difficult.

Work in an uncomfortable setting will cause fatigue earlier than if you fulfill all instructions.

Usually width hiscellular cloth equal to 10 to 20 cm. Models with a width of less than many drawbacks, as they are impractical and will immediately fail. But note that too wide tools will not give you comfort.

For the manufacture of hacks, alloy steel, which differs from the conventional large carbon content and silicon of the following brands:

65g, 60 C2a.
8 XF, 9 XF, 9 XC.
Y7, Y7A, Y8, Y8A, Y8G, Y8GA, Y9A, Y10.

Metal is tempered with a special effect of a magnetic field, thanks to which high-frequency electric current appears.

When distributing on the surface, it warms upper layer Metal, after which they do harden cold water. According to the standard, the hardness of the metal should be 45 HRC, but it is better to give preference to the products, the hardness of the canvases of which will be from 55 to 60.

At the tree hacksaw with high density There will be good flexibility indicators, but the teeth will be stable. Externally, when inspecting the quality of the tool, you define on a dark shade of sharpened teeth.

What should the teeth be

Another one an important factor The performance of the instrument and its work during the pickle is the size of the teeth. Such an indicator, as the accuracy of sawing, has the designation of TI, which means the number of teeth inch (2.54cm).

Between this technical parameter Next connection:

The canvas with the cloth gives bigger high speed When working, but in this case, expect an inaccurate and rough speaker.
The cutting with fine teeth will cut a clean and accurate, but the speed of work will be at times lower.

When you are determined with the sizes of the teeth, focus on the type of material being processed.

When working with such material as a chipboard. Where you need high accuracy Cut, you should take a tool with an indicator from 7 to 9, and for logs in the garden, where the cleanliness of the cut does not play an important role, the indicator is from 3 to 6.

If you compare the usual and kaneny tooth, the difference will be that the usual long time is not stupid under household use. But the hacksaw with hardened teeth can not be reused, so when the quality of the cut will decrease, you will not be left anything else, just how to throw away.

The advantage of an ordinary tooth is that it can be sharpened. This work is periodically carried out by means of a frequency with an accident marking ( for a certificate drank).For sharpening you need to spend several times with a file for each teeth.

Depending on the type of teeth there are three types of manual hacksaw:

Some types of tools have teeth, which in shape remind a trapezium. This decision made a new generation of hacksaw bells, which wear-resistant and an order of magnitude stronger.

But it is worth considering that the sharpening of such a canvase is a difficult task, as it is difficult to give the form a difficult figure of small teeth. It strongly reduces the service life of the instrument, at the end of which you will have to change the canvas or choose another good wooden hacksaw.

Now the market has become increasingly new models of hacksaws, which are created for cutting not yet succeeded. Between the teeth, it was easily passing small sins, and do not make it difficult to work.

Narrow

It is a small saw, which is a flat straight canvas and handle. With her help, you can perform a number of minor work: cut the curvilinear details, make a cross-cutting propyl and so on.

It is made of canvas with bilateral teeth in the form of a triangle, sometimes with a parallel sharpening. The disadvantage of the tool is that when approaching when working canvas can deviate from the specified direction.

Standard

The hand saw with standard parameters can have any type of teeth and is most often completed with several canvases for shifts, which have different execution and type of teeth. Despite the universality declared by the parameters, such saws are not suitable for the manufacture of furniture.

With a trap

Both narrow, and standard saws when rising stiffness threshold prone to bending. In order to avoid this, the use of a furniture tool will be effective, which will be in the role of rigidity ribs. The presence of such a "retainer" will not give the opportunity to make a cut larger than the width of the canvas, as it will prevent the passage of the cloth into a tree into a large depth.

Bucket

The saw of this type is a more cumbersome device, which is a manual version of the electroball. Due to the fact that the design is founder and its threaded connection Handles, such saws can easily overcome the bitch, making cutting through the patterns and radius.

Depending on the proposed type of work and design, the saw can be:

Transverse - For cutting across the fiber tree.
Mind - for cutting along.
Point - To create holes, roundings and sawing of the figure type.
Spike - to cut the junction spikes and drinking simple geometric figures on the workpiece.

Only an archery-type hacksaw can perform all these features without additional tools.

The procedure for the choice is quite simple:

Now about handles. They are usually made from plastics. Colored handles make two plastic halves that are not very tough.
