How to choose a carbide drill?

The choice of cemented carbide drill bits should be selected according to the use scene

1. Use on advanced machining centers

Choose solid carbide drills, which are made of fine-grained cemented carbide materials. In order to extend the service life, they are also coated. The specially designed geometric edge shape enables the drill to 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 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, high dimensional accuracy and positioning accuracy, and subsequent finishing is unnecessary.
