Drills for concrete: what you need to know about them?

Concrete is known to have high hardness. It is hard to drill, so for such work they do not use a drill, but a hammer drill, which combines rotational and shock movements.

For drilling concrete, special drills are used. Qualitatively manufactured products can be successfully used both in everyday life and in construction. If you purchase them directly from the manufacturer, you can save a lot. Concrete drills are convenient to use, and their efficiency, durability and high technology allow them to withstand huge loads.

Drills, as they are often called concrete drills, like ordinary drills consist of a cutting part, a spiral core and a shank. The latter allows the tool to be held firmly in the drill chuck. The spiral rod is designed to remove dust and crumbs from concrete drilling. There are special varieties of drills, the core of which has a cavity inside, which removes dust by the so-called vacuum effect.

The shanks of drill bits for concrete can have various protrusions and / or recesses that determine the reliability of fixing the tool. The sizes of these elements may also be different. Boers are selected primarily by the type of shank. The workmanship of this part of the drill is usually high, which allows you to securely fasten the tool in the chuck.

As for the cutting part of the drill, it may have a different sharpening shape and a different number of edges. High-strength metal alloys are usually used to make this part of the drill. Depth, as well as the diameter of the hole to be made, determines the slope, height and radius of the grooves.

Drills on concrete are characterized by many positive qualities. They quickly cut through the material, which is ensured by the presence of special soldered plates made of superhard alloys. High drilling speed is ensured by the rapid transfer of force to the work area. The durability of the drills provides heavy-duty solder.

The dust generated during drilling is effectively removed from the hole being drilled, which significantly increases productivity. Vibrations are minimal, which is also very pleasing.

Concrete drills are characterized by a long service life and a high degree of wear resistance. This is a universal tool that can be used with almost all types of rotary hammers.

The excellent technical characteristics of concrete drills make it possible to use them for drilling not only concrete, but also other very hard materials, such as granite or natural stone. Hammerless drilling can be used to make holes in masonry, hollow brick, and other less hard materials. And finally, drill bits for concrete are characterized by an optimal ratio of price and quality, which is another additional plus in their favor.
