According to the material
1.High-speed steel drill bit
High-speed steel drill bit is the most common kind of drill bit, suitable for ordinary steel, cast iron, brass, aluminum alloy, plastic and other materials of drilling.
2.Alloy steel drill bit
Alloy steel drill bit is made of high efficiency alloy, high drilling efficiency, long life, suitable for steel, copper, copper alloy, nickel alloy and other high hardness materials drilling.
3.Tungsten carbide drill bit
Tungsten carbide bits, also known as carbide bits, have extremely high hardness and can easily drill hard materials, such as cast iron, alloy steel, stainless steel and so on.
According to the shape of points
1.Common drill bit
Ordinary drill bits are the most basic drill bits and are mainly used to drill holes less than 10mm in diameter.
2.Reaming drill
Reaming drill bits can increase the diameter of existing holes.
3.Core drill
A core drill is a specialized drill bit that is usually used to accurately locate the location of a drill hole.
4.Step drill
Step drill is suitable for situations where radial step holes need to be machined.
5.Taper drill
Taper bits are suitable for many applications and can drill holes of different sizes over a wide range.
6.Woodworking drill
The shape of the woodworking drill is usually conical or spiral, mainly used for processing wood.
According to the drilling method
1.Center drill
A center drill is a special type of drill bit that is often used to reduce the likelihood of displacement during drilling.
2.Coolant drill
Coolant bit use requires additional coolant injection, which can reduce the temperature during drilling and extend the service life of the bit.
Different bits are suitable for different workplaces and materials, and choosing the right bit can improve efficiency and accuracy.
