There are four basic types of carbide drills for users to choose from: solid carbide drills, welded carbide drills, carbide indexable insert drills, and replaceable carbide crown drills. Each drill has its advantages suitable for specific processing conditions.

The solid carbide drills produced by the cemented carbide drill manufacturer are suitable for advanced machining centers. This drill is made of fine-grained cemented carbide material. In order to prolong the service life, it is also treated with TiAlN coating. The specially designed geometric edge shape enables the drill bit to have an automatic centering function and has good performance when drilling most workpiece materials. Chip removal control and chip removal performance. The automatic centering function of the drill bit and the strictly controlled manufacturing accuracy can ensure the drilling quality of the hole, and there is no need for subsequent finishing after drilling.

The welded cemented carbide drill is made by firmly welding the cemented carbide crown to the main body of the steel drill. This type of drill uses a self-centering geometric edge profile, with low cutting force. It can achieve good chip control for most workpiece materials. The processed holes have good surface finish, high dimensional accuracy and positioning accuracy, and no follow-up accuracy is required. Processing. The drill bit adopts internal cooling method, which can be used in machining center, CNC lathe or other high rigidity, high speed machine tools.

Drills with cemented carbide indexable inserts can process various apertures, and the processing depth ranges from 2D to 5D (D is the aperture), and can be applied to lathes and other rotary processing machines.

The replaceable carbide crown bit is a new generation of drilling tools developed in recent years. It is composed of a steel drill body and a replaceable solid carbide crown. Compared with welded carbide drills, its machining accuracy is equivalent, but because the crown can be replaced, the machining cost can be reduced. Improve drilling efficiency. This kind of drill can obtain accurate hole diameter increase and has an automatic centering function, so the hole diameter processing accuracy is very high.
