How to choose a cemented carbide drill?

The choice of cemented carbide drill bit is to be selected according to the use scene

1. Use on advanced machining centers

Choose solid cemented carbide drills, which are made of fine-grained cemented carbide materials. In order to extend their service life, they have also been coated. The specially designed geometric blade makes the drill have a self-centering function. Good chip control and chip removal performance when working with workpiece materials.

2. Use on lathes and other rotary processing machine tools

Choose hard alloy indexable insert drills. This drill has a wide range of processing apertures, and the processing depth ranges from 2D to 5D (D is the aperture).

3. Machining center, CNC lathe or other high-rigidity, high-speed machine tools.

Choose welded cemented carbide drill bits or replaceable cemented carbide crown drill bits. This type of drill is firmly welded to a steel drill body with a cemented carbide crown or consists of a steel drill body and a replaceable solid carbide crown. Combination. It adopts self-centering geometric edge shape with small cutting force, and can achieve good chip control for most workpiece materials. The processed hole surface has good surface finish, dimensional accuracy and positioning accuracy are high, and subsequent finishing is unnecessary.
