The unique properties of diamond are used in the manufacture of tools for processing. The hardest mineral and tools made from it have incredible strength. Diamond drills are in great demand among professionals and amateurs. The market is filled with products from Russian and foreign manufacturers of different types and different target orientations. In order not to be mistaken in the choice, it is necessary to find out all the parameters of the technical plan, the properties of the material that will need to be processed, the capabilities of the existing equipment.
Peculiarities
A diamond drill in modern conditions is made in different ways. The features of the tool depend on the technology . By sintering and processing by powder metallurgy methods, tools are obtained high quality, durable . But using this technology, only dimensional models can be made, for example, ring drills. Thus, the products are monolithic, extremely durable, but bulky. If you make small cutting zones using this technology, then the tool will turn out to be fragile, mechanical action will quickly disable it.
Electroplated diamond type . Coated on electroplating equipment, they make tubular diamond drills with a tapered cutting tip. This technology makes it possible to create small diamond-coated tools of complex appearance and design. The grains are arranged in one row here, so the durability is low, especially at the cutting tips of the tool. The resource of such a product is small, but the cost is also quite budgetary.
Diamond type tips do not need cooling and constant sharpening; periodically during operation, you need to reduce the speed. As for the parameters, all drills differ in the following characteristics:
- the size of the cutting zone;
- the length of the working part;
- form;
- the number of segments;
- cutting method.
As for the advantages of such drills, there are:
- the possibility of reusable use;
- the quality of the holes being created;
- variability of tools.
Applications
Diamond-type tools are effective in the processing of various surfaces and materials, before which other tools are powerless. The characteristics of this type of drill make it possible to successfully create holes in high strength materials. They are used in works:
- for concrete, including for drilling in reinforced concrete structures;
- on tiles;
- on ceramics;
- on granite, suitable for porcelain stoneware tiles;
- on glass;
- brick by brick;
- stone of natural and artificial origin.
Drilling all kinds of tiles It is most convenient to make with devices of the holding type, so it is easier to center the hole . With the help of drills, electrical outlets are mounted, optical and electronic devices are created. Diamond tools are used in construction, mechanical engineering, and actively, it is impossible to replace them in these areas.
As for domestic use, diamond drills have also found a use here, they are used for drilling in glass, mirrors, tiles of various types, stone and concrete structures.
Main types
Diamond-type tools are available in a variety of shapes and diameters. They can be generic or material-specific. The working part may look like this:
- by the shape of the cylinder - this is how an annular and tubular drill looks like, a possible diameter range from 32 to 350 mm;
- in the shape of a ball;
- in the shape of a cone - a traditional look, visually reminiscent of drills on metal surfaces;
- in the shape of a feather (spear).
To ensure rotation, you can use machine tools, electric screwdrivers, screwdrivers, drills . The rotating speed will depend on the diameter and material. The smaller the diameter, the higher the speed. For example, drills ranging in size from 1 to 3 mm will provide a speed of 6 thousand revolutions, and with a diameter of 25 to 50 mm - no more than 1200 revolutions. Conical drills from 20 mm to 85 mm are used for drilling stone, glass, ceramic and tile surfaces.
It is very important to choose the right tool to ensure accurate holes and accurate execution . It is also imperative to follow the recommendations of a technological nature. An important factor is the choice of the manufacturer of the drills. These three parameters determine how long the tool will last and whether the quality of the work performed will satisfy you.
Popular manufacturers
There are a sufficient number of reputable manufacturers of diamond drills on the modern market. There are many worthy foreign and domestic firms among them.
- " MonAlit", Russia . Drills are offered in sizes from 3 to 700 mm. The resource of work is the highest.
- Hawera, Germany . Drills of high resistance, different, but not too large diameters, self-cooling.
- Bosch, Germany … They produce high quality dry-drilling drills designed for processing wood, brick, concrete, and ceramics.
In addition to these manufacturers, you can safely purchase products from companies: Makita, Metabo, Stayer, FIT. The tools of these companies are reliable, although the price is quite high. Among the Russian brands are Enkor, Zubr, Interskol. You can also consider buying a drill from Chinese firms, provided that it is quite expensive. In general, in pursuit of cheapness, you can purchase a tool that turns out to be disposable. A good diamond-type drill cannot be inexpensive, since serious technologies and expensive high-quality materials are used in their manufacture.
Some manufacturers create drills of the budgetary category, but most of them are formed with various kinds of malfunctions, the material is of poor quality. It is also important to purchase the tool in trusted stores, as the market is oversaturated with fakes.
Experts recommend paying attention to the color of the instruments, as a rule, fake ones have a dark shade, in comparison with the originals. This is due to violations of the technological plan during manufacture.
Terms of use
It is necessary to use diamond drills, taking into account the specific features of the tool and the material being processed. Electroplated diamond spraying forms drills that can be used at the highest RPM, so they are as productive as possible. There are a number of rules to consider:
- the larger the drill size, the fewer revolutions possible;
- the pressure is carried out with different forces, glass does not require much labor, concrete does.
If you break these rules, then the drill will fail very soon .… Therefore, before buying a set of tools, decide what material you plan to process. Industrial and household drills are completely different in the number of possible applications. For comparison, an industrial drill for porcelain stoneware can be used about 120 times, a household drill about 70 times.
It is also important to take into account the required drilling depth per pass, this characteristic depends on the diameter. Never use diamond drills and impact tools. These include hammer drills, impact drills. If the drill is used in tandem with these machines, the crystalline layer is destroyed. Only rotary type tools are allowed.
