Tungsten Carbide Blanks (Carbide Hob Blanks)

This line of tungsten carbide blank is a perfect raw material solution for producing fine-pitch gear hobs. As a kind of cutting tool blank, our tungsten carbide blanks offer a longer lifespan which is as 8-40 times as that of the high-speed steel. Moreover, our carbide hob blank can effectively increase the products' degree of finish.

Our tungsten carbide blanks are fine-grained, and thus the resulted hob cutter offers excellent performance in cutting tractable materials. This kind of carbide preform is capable of improving the working efficiency and effectively guaranteeing the cutting precision of gear hobs.
