Assortment overview
All accessories are marked according to the diameter of the hole to be drilled.
- Twist drills or twist drills are one of the most popular varieties in metal and woodworking, therefore they are used most often. They have a diameter from 0.1 to 80 mm and a length of the working part up to 275 mm.
- Flat or feather drills are used to produce large diameter holes. The device has the form of a flat plate, is made with a shank or is fixed in a boring bar.
- The Forstner drill is similar to the nib drill, the modification has a cutter-milling cutter.
- Core drills are used when it is necessary to cut only the annular part of the material.
- The single-sided drilling model is used to obtain accurate diameters. Its sharpened edges are only on one side of the drill axis.
- The stepped model has a cone shape with steps on the surface. Each of these steps drills a certain diameter. With its help, drilling of different diameters is carried out without changing the equipment.
- To obtain tapered holes, a countersink drill is used.
- Diamond and pobeditovy types are used to work on ceramic tiles, glass, concrete, stone, brick, porcelain stoneware.
All types have different types of shanks:
- SDS, SDS +;
- conical;
- cylindrical;
- three-, four-, hex shank.
You can purchase both a single drill and a set. Manufacturers offer universal kits specialized for working on glass, tiles and ceramics. There are sets for metal, concrete, wood. A set of drills for metal has excellent performance. A set of 19 drills from 1 to 10 mm, with cylindrical shanks. The set is in a sturdy metal box.
The tool is made of high-speed steel, unique technologies have created a tooling that can withstand high impact and temperature loads. The spiral shape facilitates chip evacuation. It is used on machine tools, in working with drills, screwdrivers.
Description
Drills from the Matrix company are intended for:
- for drilling - getting friction holes;
- reaming - expansion of existing ones;
- drilling - getting blind recesses.
Hexagonal and cylindrical are used in drills and screwdrivers of any kind. For jaw chucks, a triangular shank is used. SDS type shanks are specially designed for rock drills.
The Matrix company has special requirements for the tool, both professional and manual, therefore the drills from this manufacturer are able to withstand a long load. In production, high quality carbide steels are used. Additional coating technology is applied.
Drills made of steels with added vanadium and cobalt received an excellent recommendation from consumers. Matrix drills are highly durable and wear-resistant; cobalt tools drill through even hardened metal. Drills for ceramic tiles, Forstner and others show excellent quality and accuracy results, give neat cuts with an even edge.
How to choose?
The choice of drill depends on what material it will work with. For wood, the choice of equipment depends on the diameter of the hole: for small diameters of 4-25 mm, spiral models are chosen, for an increased diameter, feather models are taken, since they have a minimum size of 10 mm. An extendable centrobore pen is used when the diameters are frequently changed.
Working with concrete requires carbide tooling, which is not inferior in strength to diamond. This is a winning tool that surpasses other options in terms of durability.For drilling metal, choose spiral, stepped or countersink drills made of steels with the addition of cobalt, molybdenum.
This tool has a three-layer coating of titanium nitride, aluminum and allows you to drill alloy and stainless steels.
