There are five main types of brazed tungsten carbide blade in China currently:

A-type blade is used in 90° bullnose tools, facing tools, etc.

B-type blade is used in straight bullnose tools, facing tools, hole boring cutters, etc.

C-type blade is used in straight and bend bullnose hole boring cutters, glaives, etc.

D-type blade is used in cut-off tools, grooving tools, etc.

E-type blade is used in threading turning tools.

Brazed tungsten carbide blades will differ according to different blade groove shapes:

Open slot: It is simple for manufacture, smaller in welding area, suitable for C-type blade and sometimes D-type blade as well.

Semi-closed slot: It is relatively difficult for manufacture, but firm in blade welded. It is suitable for E-type blade.

Closed slot: It is difficult for manufacture, but firm in blade welded. It can increase welding area and is often used in threading cutters and suitable for E-type blade.

Undercut groove: It is used in cut-off tools and grooving tools of relatively smaller base area, thus increasing welding area and bond strength. It is complicated for manufacture and suitable for D-type blade.
