It is unlikely that in the modern world there is at least one man with “straight arms” who has never used, or at least not heard of, the so-called Pobedit drills. In fact, in such drills only the tip is coated with a special material called pobedit. Let's take a closer look at this material.
Wins - composition and properties
It appeared in the USSR back in 1929. The material is a hard metal alloy. The composition of Pobedite includes tungsten carbide and cobalt, the mass ratio of which is 90:10.
Pobedit is characterized by high strength, wear resistance and hardness. However, products made from Pobedite exhibit such disadvantages as causticity and fragility upon impact, so in practice Pobedite spraying and the use of cutting and drilling tool tips are used. Thanks to the tips and spraying, the tool is given properties that significantly increase wear resistance to abrasion and dullness.
Manufacturing method
The alloy is produced in industry not by casting, like cast iron and copper alloys, but by sintering a pressed mixture of composite powder. A ceramic-metal composite alloy is created by mixing fine tungsten carbide powder and cobalt as a binder. The resulting fine powder mixture is placed in special molds in the form of plates of various shapes and sizes and sintered. Due to the high sintering temperature, which is close to the melting point of the binder material, the result is a unique material with high strength and hardness.
Unlike classical technology, the main components of the alloy can be replaced with other analogues, for example, nickel can act as a binder. However, in practice these alloys are also usually called pobedit.
Scope of application
It is practically indispensable in the mining industry, where it is used as a spray coating for drilling parts of hard rock drilling equipment. In metalworking, pobedit coatings and tips are used in metal-cutting equipment and drawing tools. Pobeda also finds its application in woodworking. Pobedit's high hardness and heat resistance effectively protects equipment used in difficult conditions, giving it good wear resistance characteristics.
At the domestic level and in construction, drills for rotary hammers and impact drills are used for drilling concrete walls.

Will win
Will win- a hard alloy of tungsten carbide and cobalt in a mass ratio of 90:10. Possessing high hardness (80-90 on the Rockwell scale (scale A, HRA)), it is used in rock drilling, metalworking, woodworking and as critical parts that require high hardness or heat resistance.
Pobedit was developed in the USSR in 1929, where it was mainly used for cutting tools. When creating, powder metallurgy methods are used.
Metal-ceramic composite alloys have particularly high hardness. Pobedit is made in the form of plates of various shapes and sizes. The manufacturing process is as follows: fine powder of tungsten carbide or other refractory carbide and fine powder of cobalt or nickel binder metal are mixed and then pressed into appropriate shapes. The pressed plates are sintered at a temperature close to the melting point of the binder metal, which produces a very dense and hard material. Plates made of this super-hard alloy are used for the manufacture of metal-cutting and drilling tools: they are soldered onto the cutting tool holders with copper. No heat treatment required.
Currently, other tungsten-cobalt composite alloys have been developed, but the name “win” continues to be used for them.
Will win (factory)
"Win"- non-ferrous metallurgy enterprise in Vladikavkaz (North Ossetia). Produces products from tungsten and molybdenum, as well as rhenium.
The decision to build the plant was made by the USSR Ministry of Non-Ferrous Metallurgy in 1946, construction began in 1948. The choice of location was influenced by the proximity of the source of raw materials (Tyrnyauz Mining and Processing Plant in Kabardino-Balkaria), transport connections, the presence of the industrial site of the Electrozinc plant and the possibility of cooperation between the two plants in a number of economic functions. Vladikavkaz also had an educational and scientific base - the North Caucasus Mining and Metallurgical Institute.
Already in 1948, the first products made of hard alloy, which in those years was called “Pobedit”, came out at the experimental site of the plant. The name of the alloy gave the plant its name.
Now JSC Pobedit occupies an area of 39.7 hectares, the company employs about 1,800 people.
In January 2009, production at Pobedit was completely stopped, and subsequently partially restored. It is planned to reach 80% of the 2008 result.

The purpose of any drilling, as is known, is to obtain an even and accurate sized hole in the product or structure being processed. To solve such a problem, it is very important to choose the right tool; for drilling softer materials, a regular drill is suitable, and for processing harder and more durable materials, you will need a carbide or pobedit drill. The use of a tool whose cutting part is made of carbide material allows for effective processing of stone, brick or concrete.
How to choose the right drill
Despite the apparent simplicity of the process of drilling holes in various materials, solving such a problem is not so simple. Many home craftsmen have encountered a situation where attempts to drill a hole in a wall or any other structure using an electric drill and a seemingly high-quality drill ended in failure. The main reason for such problems lies not in the wrong choice of drill and lack of drilling skills (although these aspects are important), but in the use of the wrong drill. In addition, you must not only choose the right tool, but also have an idea of how its cutting edges should be sharpened.
When preparing for drilling, the following rule should be taken into account: the drill must have a greater hardness than the hardness of the material in which the hole must be made.
If you try to make a hole in a concrete wall with a metal drill, you will most likely have to throw it away, since harder material will quickly render it unusable. This tool, made of high-strength steel, can be used to work with products made of wood, plastic, non-ferrous metals and steel alloys: it does an excellent job with them.
If you need to make a hole in concrete, brick or stone, that is, in materials of very high hardness, it is necessary to use a Pobedit drill. This drill differs from a regular drill in that plates of exceptionally high hardness are soldered onto its cutting part. Since the Pobedit alloy is predominantly used as the material for the manufacture of the latter, such tools began to be called Pobedit drills.
A characteristic feature of a Pobedit drill is a soldered tip made of the strongest alloy
What is it that will win
Pobedit, an alloy containing 90% tungsten and 10% cobalt, was developed in 1929 by Soviet specialists. The main task that the developers set themselves was to create a material capable of imparting exceptional hardness to the working part of the cutting tool. Pobedite brazing began to be made from the new alloy, which made it possible to significantly increase the efficiency of using drills, as well as to process high-strength materials with their help.
In the time since the appearance of Pobedit, the alloy has been constantly modernized. As a result of this modernization, quite a lot of varieties of tungsten-cobalt alloys have been developed, many of which are distinguished by higher strength, more affordable price and ease of production technology. Despite the fact that the ratio of components contained in such alloys may differ greatly from the composition of classic pobedit, they are still called pobedit.
It should be borne in mind that a drill with a Pobedit tip does not cut, but crumbles the material being processed. That is why a drill tipped from Pobedit is optimal for making holes in concrete, stone and brick, but is not suitable for processing wood, plastic and steel. When trying to drill into a wooden product, such a tool will simply tear the wood fibers. As a result, the inner surface of the hole will be “shaggy”, and its diameter will be larger than required. It is also not recommended to use a Pobedit drill for metal work: it will not be able to form a high-quality hole in such material.
Until recently, drills of different categories were used to form holes in materials of varying hardness. Today, drills with various pobedite tips are produced, which are specially designed for drilling materials that differ in structure and degree of hardness.
Design of drills with pobedit plates
Drills produced with a pobedit tip initially have the required cutting angles, so there is no need to sharpen them additionally. The cutting part of the drill with pobedite tips is formed from two “shoulders”, approximately equal in width. The point at which such “shoulders” intersect will coincide with the center of the hole being formed, and the size of the widest one will correspond to its diameter. The axis of rotation of the Pobedit drill will coincide with the center of the hole if the width of the “shoulders” is the same. If there is a difference between the width of the “shoulders,” then the diameter of the hole being formed will differ from the transverse dimension of the tool by its value. If there is a difference in width between the elements of the cutting part, this can lead not only to an increase in the load on the drill and the operator’s hands, but also to breakage of the drill.
If drills with pobedit tips become dull, they can be sharpened in the same way as regular ones. When sharpening, you should keep in mind that the alpha angle of the cutting part of the drill should be smaller, the harder the material being processed. Pobedit is very afraid of overheating, and this should definitely be taken into account when sharpening. In order not to encounter a situation where the pobedit carbide tip begins to crack or even separate from the main part of the tool, it is necessary not to let it overheat and cool it as often as possible, for which you can also use ordinary water. If, nevertheless, the victorious elements of the drill overheat, they should be allowed to cool in natural conditions and in no case subjected to sudden cooling with liquid (this can lead to their cracking).
The modern market offers a wide variety of drills with carbide-tipped pobedit tips, which are designed for processing certain materials. Information about the purpose of such drills, if they are produced in serial conditions, can be found on the packaging.
A price that is too low for a pobedite instrument should raise suspicions, as this usually indicates that you are looking at a low-quality product of unknown origin.
Assortment of pobedit drills
Today, every master can purchase any drills, including pobedit ones. On the modern market, such tools are presented in a wide variety of diameters. In this case, drills can be purchased either individually or in whole sets. Experts recommend purchasing small-diameter drills with a reserve, since such tools often break during use.
Prices for drills vary quite a lot. It all depends on the country in which the instrument was made and how well known the brand under which it is produced is known. The most expensive and high-quality drills are from well-known European companies. The cheapest include tools from unknown manufacturers, which not only do not have high strength characteristics, but also do not always correspond to the declared geometric parameters.
The fairly high price for drills with pobedit tips made by renowned manufacturers is completely justified, since these products are distinguished by such advantages as:
- accuracy of soldering of pobedit tips (connection points are almost impossible to detect visually);
- high quality and sharpening accuracy;
- stated warranty period during which the cutting part of the tool should not become dull.
After the warranty period for maintaining sharpening parameters ends, the tool loses its uniqueness and can be used as a regular drill with pobedite tips.
It is worth telling separately about individual manufacturers of drills tipped from Pobedit.
DeWalt Extreme SDS-Plus Series Drills
Pobedit-tipped drills, manufactured by the famous DeWalt company, have working diameters of 4, 5, 6, 8, 10, 12, 14 and 16 mm. The shank of drills whose diameter does not exceed 12 mm has a round shape, while for tools with larger diameters it is hexagonal, which allows the drill to be more securely fixed in the chuck of the equipment used.
The cutting edge of Pobedit drills from this manufacturer has a serrated configuration, which helps to effectively process even concrete, the structure of which contains reinforcing bars. The shape of the groove of such a tool, when viewed in cross section, resembles a jug, which ensures effective removal of dust generated during the drilling process.
To fix the pobedit carbide tip on the drill, special technology and solder containing copper are used, which makes this connection more resistant to overheating. Thanks to the high quality characteristics of such drills, the holes created with their help are obtained with virtually no chips at the edges.
Bosch pobedit-tipped cutting tools
Drills from the well-known German manufacturer - Bosh - are presented on the modern market in a wide range of working diameters (from 3 to 25 mm). This company produces drills specifically designed for processing various materials (the corresponding instructions can be found on the product packaging).
The company's assortment includes drills with pobedit tips intended for use in conjunction with impact drills (Blue Granite series). Products of this type, specially designed for drilling holes in masonry, have a number of advantages:
- high bending strength;
- higher durability when drilling concrete than a simple Pobedit drill;
- high quality and precision manufacturing of carbide inserts;
- a U-shaped groove, which significantly reduces clogging of the tool with crumbs of the processed material.
