The carbide drill bit is divided into four types of foundation types: integral  carbide drill bit , carbide resettable blade drill bit, welded  carbide drill bit  and can be changed to hard alloy tooth drill bit. Each drill bit has the benefits suitable for specific processing premises.

(1) Overall hard alloy drill bit

(2) Carbide replacement blade drill bit

The drill bit of the reducing blade is installed is very wide, the machining depth is 2D ~ 5D (D is aperture), which can be applied to the lathe and other torsion machine tools.

(3) Welding hard alloy drill bit

Welded steel  carbide drill bit in the drill body smoothly welding a crown made of cemented carbide. This drill bit uses a self-care geometric blade type, which is small cutting. It can realize brilliant chip maintenance, and the finish of the hole is good, and the size accuracy and positioning accuracy are high. No need Perform subsequent finishing. The drill bit is used in an internal cooling system, which can be used in machining centers, CNC lathes or other high rigidity, high speed machine tools.

(4) Change the hard alloy tooth drill bit

Changes to the hard alloy tooth drill bit is a new generation of drilling tools. It is combined by steel drill body and can be converted to a combination of a coated crown, compared with welded hard alloy drill, and its processing accuracy is eight or less, but because the crown can be changed, it is to reduce processing costs Increase the yield of drilling. This drill bit obtains a cutting aperture size increment and has a self-care function, which is high in aperture.

Main advantages of hard alloy tools:

Reduce the cutter downtime, improve production and processing time;

Accelerate the cutting and installation time, improve the economics of small batch production;

Improve the standardization and rationalization of the tool;

Improve the management of tools and the level of flexible processing;

Expand the utilization of the tool and give full play to the performance of the tool;

Effectively eliminate interrupts in tool measurement work, and cemented carbide tools can be predicted by wire.
