Stainless steel drills. What better. The basics of stainless steel drilling are the choice of drill for stainless steel. Features of drilling in field conditions

Industry development and high product certification requirements in international markets lead to the widespread use of high-quality stainless steel. Designers when creating projects prefer welding connections of individual nodes.

The connection is bolted, the riveted from this did not suffer and is often used in modern structures. Drilling of stainless steel May be needed to create technological holes. Presented in this article the material will give general concepts and the features of this process with anti-corrosion alloys.

Preparatory work

Preparatory work consist in eliminating some negative factors associated with the drilling of stainless steel. Consider what properties make difficulties in this process:

Chemical composition stainless marks Steel helps to increase the plasticity of the metal. The chips when drilling such steels sticks to the drill, from this cutting edges are excluded from the process, and on the walls inside the unfinished hole, slope is formed. Such a superficial slope makes it difficult for further processing and changes physical properties in this place.
The heat removal from the rotation heated and cutting the drill occurs over the metal surface. Without conducting warning events, you can get a section-colored section around the drilling. In addition to spoiled decorative surfaceThis reduces the corrosion resistance and requires additional technological operations to restore the specified parameters.

To avoid the shortcomings described above, it is necessary to decide before drilling to be solved as the surface will cool and what to do to eliminate sticking chips. Among effective methods Suitable water. If the volume of the muscles is more than one hole with a diameter of 10mm in a sheet with a thickness of 2 mm, then it should be thought about cooling with an oil or a special emulsion.

Attention. Cooling with water when drilling a stainless steel is made during the process itself. Cooling by lowering the hot drill in a jar standing nearby leads to hardening and metal leave and loss of basic properties. The coolant is fed to the contact point when drilling. To reduce the consumption, you can put a rubber ring on the surface, surrounding the contact point.

Drilling modes

The correct choice of drilling mode is the key to getting a high-quality hole. The main components of the speed, feed and torque.

Cutting speed - The conditional value defining how quickly the point rotates on the surface of the instrument relative to its center. This means that for different diameters of drills You need to choose different revs to achieve the same cutting speed.

Example. For steel 08x13n with a thickness of 10-15 millimeters in the directory, the speed of cutting 20m / min is indicated. If necessary, drill a hole with a diameter of 1 mm. The speed of rotation of the spindle of the drilling machine should be 6366 revolutions per minute. If the hole is drilled with a diameter of 10 mm, then turns should not exceed 637 revolutions in 60 seconds.

Drill feed In the metal means the value of moving to the depth of the opened hole for a certain number of revolutions. That is, this is the immersion rate. It is measured in millimeters for 1 turnover. It is important to withstand recommended values \u200b\u200bto obtain a qualitative result and reducing the effects of chips on cutting edges.

Torquetransmitting drill during drilling process is an important factor For drill and material, determines the selection of steel for drill and composition of cooling fluids. By conventional words, it is a load on the drill, resulting from the resistance of the material by deformations created by the edges of the drill.

The choice of each of the parameters is due to the stainless steel brand, the sheet thickness or part, the choice of equipment, the selection of the cooling method, the material of the drill, surface roughness and other factors. By major brands there are many reference literature and regime cards. Proper selection And the high qualifications of the technologist, which make up the regime cards, will avoid additional processing operations and finishing, reducing the cost of production.

Drills for stainless steel.

The variety of drilling equipment today can put even experienced professionals in a dead end.

The most common are cobalt drills. Their name indicates the presence of cobalt in chemical composition Alloy. Stainless steel drill belongs to high-speed steel products. The increase in the percentage of cobalt increases the redstability, the alloy will retain its properties after heating to the temperatures of red cagine. These include instrumental steel P6M5K5, main material for manufacture cutting tool For stainless steel in domestic and foreign markets.

In addition to the material, the design of the drill itself is important. The most expensive and qualitative of them are manufactured using technology when grooves form on grinding machines. The absence of deformation stresses makes them stronger and expands the mode parameters of drilling. Such grooves do not have microscopic sizards and simplify the output of chips, preventing the sticking of grooves. The coaching angle of drill must be 135 degrees. This leads to a reduction in the load.

Drilling technique

The drilling of the opening of more than 6 millimeters must be produced in two stages. First, the hole is drilled with a diameter of up to 5 mm, and then it is brought to the required diameter. The absence of internal voltages before drilling will be simplified and expand the range of modest parameters. This will prolong the service life of the drill, will avoid surface overheating.

Before drilling stainless steel, find out its brand, thickness, recommended drilling control parameters. Decide with coolant. If there is no missing, it is possible to use vegetable oil (olive or sunflower), sled, emulsion of the household soap in water.

It can be definitely said that any home keeps their riddles. Their number in each house is yours. To cope with them, as a rule, you need to use the advice and knowledge of other people who are familiar with similar problems. One of these complex tasks is considered to drill a stainless steel. Without possessing certain knowledge and skills, you will probably try to make a hole you need into a stainless steel layer, but unsuccessfully.

Instructions for the implementation of this event:

1. First of all, in order to do a hole in the stainless steel layer, you need to use a special lubricant. Most often to get this lubricant, it is necessary to mix a certain type of sulfur mixed with machine oil. The sulfur needed for this mixing is sold in special stores. When buying it, pay attention to the name of this sulfur. Its name may be as follows:

Erotic sulfur.
Colloid sulfur.
Sulfurian.

If you bought sulfur, which is called "colloidal sulfur" or "sulfur", it can be mixed with oil in the form in which it is in the package. But in the event that you have a "sulfur", you must first develop it, then add oil and mix.

2. To create a lubricant with much more efficient properties compared with lubricant of sulfur and machine oil, you need to mix sulfur with fatty acids. Where to take these fatty acids? For this, the lowest laundry soap Grind, and then add hot water. In the cooked soap solution, it is necessary to pour a significant amount of hydrochloric acid, for this, take technical hydrochloric acid. After the reaction of the interaction of these substances, fatty acids will be on the surface of the tank. Then add a lot to this vessel cold water. This will lead to the fact that fatty acids thicken, and they can be removed from the surface. Spend 5 precipitation procedures of fatty acids. First add hot water, then cold, collect them from the surface, and so on.

3. Collecting sufficient number Fatty acids, mix them with gray. Proportions must be 6: 1. Thus, the lubricant for holding a hole in stainless steel is prepared, it remains to use it. Do not forget that, carrying out the process of drilling, the drill should not overheat. Periodically make a break to work so that the drill can cool. Not following this instruction, the lubricant may instead of helping to have difficulty in performing this event.

Compliance with uncomplicated rules

In order not to encounter difficult situations, such as, strong overheating of drilling site, extreme heating of the drill and others, must be observed simple rulesIt will help to perform absolutely smooth holes without concomitant time and money. It should also be borne in mind that due to a viscous structure of stainless steel, the reservoir of the stainless steel should be drilled on small revolutions to prevent overheating of the drill. Drills you need to use only very sharp. In addition, in order to prevent significant overheating of the drilling site, which will lead to great difficulties in carrying out drilling, every 10 seconds it is necessary to minimize the temperature of the drill.

Follow the chips during the period of carrying out drilling, if it turns out everything is smaller and darker, this means that the drill fastened, and the place of the hole in the stainless steel overheat. Therefore, you must divert the drill or change to another to successfully finish the work started. As a rule, it is necessary to start drilling with a drill having a small diameter, the size of which, respectively, four or five. Then gradually go to the drill that has the appropriate size for obtaining the desired hole. Performing a drilling process in a similar way, you can make a smoother hole, and at the same time strongly reduce the time spent on it.

Special stainless steel drills and cooling formulations for them allow you to quickly and comfortably make the opening of the desired size in the "stainless steel".

Many home craftsmen who are accustomed to do everything with their own hands, are very surprised when they fail with help regular drill Drill a hole in the "stainless steel". Such steel from other metals is distinguished by an increased viscosity, so the drill is almost immediately heated as soon as a person begins to process the product from a stainless alloy.

And this means that the operation can go through successfully only if you take care of the quality cooling of the drilling tool.

To cool the device used to drill holes in a "stainless steel", a special lubricating composition is usually used, consisting of sulfur and machine oil. The sulfur can be used both colloid and special for fusion. In building stores, the latter is sold specifically called "for fusion" (sometimes it can be called "sulfur"). It is usually allowed to be used without any additional preparations. If you have purchased the sulfur of large fractions, it should be thoroughly overcurned and only after that mix with machine oil.

The drilling of holes in stainless steel structures will be at times more efficient when the cooling composition of the coolant made on the basis of fatty acids and all the same sulfur. These acids do not need to buy anywhere, make them themselves. To do this, take the cheapest household soap, grind it, and then pour the resulting mixture into hot water. Solynaya add to this composition technical acid And waiting until the fatty acids needed to emerge on the surface.

As soon as the acids rise upstairs, it is necessary to pour into the container where the operation, cold water is performed (it is not necessary to regret it, the more naplet, the better). As a result, the solidification of fatty acids will begin to occur, and they can be removed without the slightest difficulties from the surface of the fluid. The voiced process of isolating the required compounds (soap in hot water - cooling - removal of acids) can be repeated several times (3-5).

Mixing fatty compounds with colloidal or "furifier" gray is carried out in compliance with the proportion of six to one. That is, one part of the sulfur needs to add six parts of acids. Professionals assure that with such a cooling makeup to dry the "stainless steel" of any thickness will be easy (if, of course, you will comply with other recommendations that we will tell below).

In cases where the drilling of holes in the horizontal plane is performed, the prepared cooling fluid is recommended to pour into a small puck of rubber or into a plug and carry out the procedure through it. When processing vertical structures You can at the points of drilling holes to attach the ball from the paraffin. This will greatly facilitate the process - you can easily drill the product in an uncomfortable spatial position.

Another feature of drilling holes in "stainless steel" is that either electric drillUsed to implement the procedure, you need to put on minimal speed. Their number may vary from 100 to 600 per minute. If you specify large quantity revolutions, even high-quality lubricating composition will not effectively cool the work tool.

When using a drill equipped with an electronic type regulator, set the required revs is easy. There is more problems when there is no such regulator on the instrument. But in such a situation there is a way out: Run the electric door for a while (literally for 1-2 seconds); Immediately press the "Start". For such a small time, its collector motor will not be able to score large speeds.

You have prepared cooling lubricant, studied all recommendations for right drilling "Stainless steel", and now you can go to the most important one - the selection of a special drill. Without it, drill non-dotting metal will not work. In Soviet times, cobalt drills with a shank of cylindrical form R6M5K5 have always been used to work with stainless steel. They were manufactured by PO State Standard 10902-77. Also used drills P18 with cobalt content at the level of five percent.

Now finding such devices for drilling holes are practically unrealistic. But it does not matter, since the construction market offers us a lot of foreign analogues. Import drilling instrument Available according to DIN 338 and has a HSS-CO marking, which becomes clear that the drill material contains at least five percent of cobalt (similar to P18 and P6M5K5). It is cobalt that gives the tool the required hardness and allows you to relatively easily drill the "stainless steel".

In addition, a good effect of processing stainless alloys demonstrates a carbide drilling tool for metal. Such drills are characterized by a sharp sharpening angle (it is done on the one hand). But they are not easy to buy them, not in all building stores they are sold. Yes, and the cost of such devices is objectively high.

Several tips on the drilling of "stainless steel":

If you drill thick steel (more than six millimeters), it is advisable to perform a process on a double technique. Its essence is that you first need to make a small "hole" with a small diameter drill and only then apply the tool with the required cross section.
The drilling of products with a thickness of 1-2 millimeters is allowed to produce usually on small revolutions (up to 100 per minute), but provided that the cutting edge of this tool is sharpened by about 120 degrees.
Stainless steel processing with a thickness of less than one millimeter should be carried out by stepped drills, which provide perfectly round holes without scoring at their ends.

Today we will talk about how and how to drill a hole in stainless steel with your own hands at home. We will also consider which technologies and methods of drilling stainless steel. We study recommendations on drills, drills and tools
Conventional drills On metal, the stainless steel is perfectly rolling, if only the drills are not Chinese. But there is one nuance. The stainless steel is very viscous, the drill is quickly overheated and sit down, and a solid slope is formed in a non-shifted hole. Therefore, it is necessary to use coolant, for example, oil under the drill, but in the extreme case water will go. How and how to properly drill a stainless steel - we list ways:

I somehow drill, the blanks were not very big, so simply took a plastic bath, threw a piece of plywood, on top of the workpiece and poured with cold water so that the level was somewhere on a centimeter one and a half above the workpiece. Dried and stood without problems.

It is better to use the usual (old Soviet) drills from steel R6M5, or that even better p18. When drilling a drill with a diameter of 3mm turns not more than 1000 rpm. Diameter 6mm drilling by previously drilled hole 3mm, turns no more than 500 rpm. The drill must always be sharp. As coolant, the stainless steel is best suited for stainless steel.

Not a bad option to use a sealing rubber ring for siphones as a wax retainer. They put on the place of the future hole, poured into it with liquids, and drill. Convenient + low coolant consumption. As nook water is not very, the stainless steel is on the drill. It is well opposed to this oil (not fundamentally what) or kerosene.

It's all good when the item can be inserted / put on drilling machine. Then it is possible to pour and rubbish the rubber ring, etc. it is ideally. I am engaged in the installation of food promotion, and the usual, black metal there is only in the frames, everything else is stainless steel, and the detail, just say, not under the drilling machine.

Holes with us are drilled by renewing. So with great confidence I will say that it is better cobalt drills For this I have not met. P6M5 (especially those from the plants) - good drills, but still in stainless steel sit quickly. There are drills even better than cobalt, tungsten. These work on a stainless steel even longer, but have a very bad feature - fragile. And sharpen only on a diamond circle and then possible with a significant wear for him. Also minus they are very high cost and they are all short. While we buy cobalt Bosch or Ruco, work quite well.

When drilling, large revs are not necessary to install, it is optimally 300-400, but not more than 1000. burn the hole, especially if the stainless is polished and the drill is baptics. If the surface is not horizontal, then the drill periodically omit into the caster or glue the ball from the usual wax (not paraffin) and drill it through it.

Those who drilled at least once a stainless steel know how difficult it happens. Ordinary drills
They are not suitable, they are elementary burn. And if a hole up to 4 mm drill
Really, the big diameters are almost impracticable.
A simple replacement of conventional drills on cobalt is also little, which gives. Sometimes dried, and sometimes at all.

In this article, I collected several important moments By drilling stainless
Steel:
- Drill a stainless steel with special drills. So-called
cobalt;

You need to drill on small revolutions. Helps a simple toostat twist
Start buttons "for minus";

If the number of holes that need to be done in stainless steel is relatively
Big, it is worth the acquisition of a low-robust drill (500-700 rpm).

When drilling stainless steel, you should always use a special lubricant. Without it, make a hole will not succeed. Such a lubricant usually consists of machine oil and sulfur. It may be sulfur for fusion, colloidal sulfur or any other. If a sulfur sulfur was selected for the production of such a fluid, it must be preloaded, the rest can be used without any processing.

A more complex variability of lubricating fluid is a consistency of fatty acids and sulfur. For its manufacture, soap takes, in this case the economic, divide it into small pieces and is dissolved in hot water. The soap solution is aging hydrochloric acid, after which you can see how fatty acids pop up.

When the cool water is added to the container, these acids are quickly hardening, thereby easily separated. Next, they need to be thoroughly rinsed.

For this, they are put into the container, add slightly hot water and interfere with about 5 minutes, gradually adding cool water. Then the water merges, and the procedure itself is repeated 4 times. For lubricating fluid, sulfur is mixed with fatty acids in a 1: 6 ratio.

Simple rules How to drill a stainless steel at home:

To avoid unpleasant moments associated, for example, with overheating of the drill, a strong heating of the drilling site and others, you need to perform several simple rules, which will make it possible to make perfectly smooth holes without additional time and material costs.

It should be borne in mind that the stainless steel has a viscous structure, therefore, in order to avoid overheating of the drill, stainless steel must be drilled exclusively on small revolutions. Drills should be as sharp. In addition to avoid strong overheating of the drilling site, which will significantly boil the further drilling of the material, it is necessary to reduce the temperature of the drill every 10 seconds.

If in the process of drilling the chips is becoming more small and dark, this indicates the bunge of the drill and overheating of the hole in the stainless steel. Before continuing the operation, the drill must be treated or replaced with a new, more acute. The drilling of stainless steel is usually begins with a small diameter drills, such as the size five or four.

Next, you can use the drills need a diameter to achieve the required size of the opening. As a result of such actions, you can significantly reduce the drilling time and make a hole as smooth as possible.

Such complex measures can be attributed to both samples of stainless steel reservoir. To declare that it is unrealistic, but without knowing some moments for you, almost to do this from the first or even from the second time.

It is almost always to make a hole in a stainless steel layer, you need to use a special lubricant. Usually, as such special material uses a certain amount of sulfur with the addition of engine oil. To find suitable Sulfur for the production of lubricant for drilling, contact the special stores. In these stores, buy sulfur under such names as "sulfur", "sulfur" or also this kind of sulfur may be called "colloid sulfur".

If you have got sulfur types such as "sulfur" or "colloid sulfur", you can use them without preparatory trainingIn other words, in the form, in what you got it. If you have gotten "sulfur", before you give it to the machine oil, be sure to finely overtake it. 2 If you wish to make a lubricant that will act much more effective than lubrication of sulfur and machine oil, try to mix the sulfur with oil, but with fatty acids. To get these the most fatty acids, take the economic soap of the lowest variety, crush it as it may be, and then dissolve in water.

Water must be so hot. In the acquired solution, pour a lot of hydrochloric acid, use techno hydrochloric acid. As a result, the reaction is all fatty acids to float the vessel surface. Then pour a lot of cool water into the container. It will give fatty acids to harden, and then you just can assemble them from the surface.

Repeat the rings of fatty acids up to 5 times. At first in hot water, then you dry out cool, separate, and without that later. 3 After you have pretty cleaned fatty acids, mix them with a grayish. Observe the ratio 6: 1.

After the grease for the drilling of stainless steel is ready, you can experience it to use it. Throughout specifically, the drilling does not rave that it is impossible to give a drill overrun. Pause pauses by drill cooling.

In another case, the lubricant will not serve as an assistant, but on the contrary, will impede work

In cases where the drilling of holes in the horizontal plane is performed, the prepared cooling fluid is recommended to pour into a small puck of rubber or into a plug and carry out the procedure through it. When processing vertical structures, you can attach the ball from the paraffin to the drilling points of the holes. This will greatly facilitate the process - you can easily drill the product in an uncomfortable spatial position.

Another feature of the drilling holes in the "stainless steel" is that the drilling machine or an electric drill, which are used to implement the procedure, must be put on minimal rev.. Their number may vary from 100 to 600 per minute. If you set a greater number of revolutions, even a high-quality lubricant will not be able to efficiently cool the work tool.

It is usually allowed to be used without any additional preparations. If you have purchased the sulfur of large fractions, it should be thoroughly overcurned and only after that mix with machine oil.

The drilling of holes in stainless steel structures will be at times more efficient when the cooling composition of the coolant made on the basis of fatty acids and all the same sulfur. These acids do not need to buy anywhere, make them themselves. To do this, take the cheapest household soap, grind it, and then pour the resulting mixture into hot water. In this composition, hydrochloric acid is added and waited until the fatty acids needed to emerge on the surface.

Many homemade craftsmen, accustomed to everybody, are very surprised when they are not able to drill a hole in the "stainless steel" with the usual drill. Such steel from other metals is distinguished by an increased viscosity, so the drill is almost immediately heated as soon as a person begins to process the product from a stainless alloy.

And this means that the operation can go through successfully only if you take care of the quality cooling of the drilling tool.

The drilling of stainless steel is always a time-consuming process that requires a certain experience, it needs increased sensitivity and attentiveness. Stainless steel, this material that is quite difficult to drill, in this matter it is necessary to use a special lubricant, it will greatly facilitate the whole process. Many really do not know how to drill a stainless steel or russian analogue AISI 201, but everything is quite simple, you only need a little experience and care.

The main component in the drilling of the stainless steel is a lubricant, since without its absence, nothing good from drilling will be released, you will only spoil the drill and the material itself. The lubricating fluid is viscous, it is quite fat and has in its composition machine oil and sulfur. Sulfur in lubricant can wear a different character, it can be a colloid sulfur, sulfur for fusion and so on.
Drilling of stainless steel, what is better to choose?

As mentioned earlier, the lubrication fluid may have the most different character, there are two types of sulfur, one is a lighter composition, and the other has complex components, such as fatty acids and sulfur.

In order to make a lubricant fluid with a more complex solution, a lot of patience and perseverance will be required, in this case you need soap (it is best to choose economic), it must be broken down on smooth pieces and dissolve in hot water.

In the resulting solution, you need to add hydrochloric acid, during the process you can see top layer Waters are peculiar allocations, it will mean that fatty acids float on the surface.

If you add some cold water to the solution, then you can see how fatty acids solidify, as a result of which they can easily be separated from each other.

After that, the fat, hardened acids should be rinsed thoroughly, it is best to take a small container for this case, pour it with warm water and actively stir for 5 minutes, and do not forget to gradually add cold water there.

All ingenious - just

Drilling, this process at which two components are loaded at once, this drill and material, during the situation some moments may occur, such as overheating of the drill, overheating of the material at the drilling point and much more. In this case, many people have questions how to drill a stainless steel, how to avoid overheating and much more, in fact everything is quite simple, you just need to slow down and drill gradually, it will avoid overheating.

Instructions for the implementation of this event:

· Erotic sulfur.

· Colloid sulfur.

· Sulfur.

2. To create a lubricant with much more efficient properties compared with lubricant of sulfur and machine oil, you need to mix sulfur with fatty acids. Where to take these fatty acids? For this, the lowest is the lowest economic soap grind, and then add hot water. In the prepared soap solution, a significant amount of hydrochloric acid should be pouring, for this take technical hydrochloric acid. After the reaction of the interaction of these substances, fatty acids will be on the surface of the tank. Then add many cold water to this vessel. This will lead to the fact that fatty acids thicken, and they can be removed from the surface. Spend 5 precipitation procedures of fatty acids. The first time add hot water, then cold, collect them from the surface, and so on.

3. Having gathered a sufficient amount of fatty acids, mix them with gray. Proportions must be 6: 1. Thus, the lubricant for holding a hole in stainless steel is prepared, it remains to use it. Do not forget that, carrying out the process of drilling, the drill should not overheat. Periodically make a break to work so that the drill can cool. Not following this instruction, the lubricant may instead of helping to have difficulty in performing this event.

Compliance with uncomplicated rules

In order not to encounter difficult situations, such as, strong overheating of the drilling site, the extraordinary heating of the drill and others, you need to comply with some simple rules, which will help perform absolutely smooth holes without the accompanying time and money costs. It should also be borne in mind that due to a viscous structure of stainless steel, the reservoir of the stainless steel should be drilled on small revolutions to prevent overheating of the drill. Drills you need to use only very sharp. In addition, in order to prevent significant overheating of the drilling site, which will lead to great difficulties in carrying out drilling, every 10 seconds it is necessary to minimize the temperature of the drill.

Follow the chips during the period of carrying out drilling, if it turns out everything is smaller and darker, this means that the drill fastened, and the place of the hole in the stainless steel overheat. Therefore, you must divert the drill or change to another to successfully finish the work started. As a rule, it is necessary to start drilling with a drill having a small diameter, the size of which, respectively, four or five. Then gradually move on to the drill, which has a suitable size for obtaining the desired opening. Performing a drilling process in a similar way, you can make a smoother hole, and at the same time strongly reduce the time spent on it.
