1.Material
The material of the drill can be roughly divided into three types: high-speed steel, high-speed steel containing cobalt and solid carbide.
1. High speed steel : Since 1910, high speed steel has been used as cutting tools, and has been used for more than a century. It is cheap, has the widest range of applications, and can be repeated grinding. High speed steel bits can be used either on hand drills or in more stable environments such as drill presses.
2. High speed steel containing cobalt : better hardness and red hardness than high speed steel, wear resistance has also been improved, but toughness has been reduced. It can also be milled to increase the number of uses.
3. Integral carbide : is a metal-based composite material, with tungsten carbide as the matrix, through a series of complex processes. In terms of hardness, red hardness, wear resistance compared with high-speed steel has a huge improvement, but the cost is also higher. Carbide tools have more advantages in tool life and processing speed than previous tool materials.
In addition, there are some special materials of the drill bit, such as diamond bits or high pressure drill bit (such as plum bit), as well as ceramic bits, polycrystalline bits and so on.
2. Features
The drill has high precision, small cutting force, and is not easy to heat deformation during processing, so the holes processed are more uniform and accurate. At the same time, the hardness of the drill is relatively high, the wear resistance is good, and the service life is relatively long.
3.Advantage
1. High precision : The drill can achieve higher processing quality than other cutting tools, creating more precise holes.
2.Long life : The wear resistance of the drill is good, the service life is long, and the number of uses can be improved by grinding.
3. Wide applicability : There are many types of drill bits, suitable for different processing processes and materials.
4.Application
Drill bits are widely used in machining, automobile manufacturing, aerospace and other fields. Specifically, in the construction field, drill bits are often used to drill into walls, floors and ceilings, etc., in order to fix various objects; In the field of machining, the drill bit is mainly used to drill the hole to the exact size and depth in order to install fasteners, etc. In the field of automotive repair, drills are often used to repair engines and bodies; In the field of home maintenance, drill bits are often used for the disassembly and assembly of furniture.
