Coated Battery Cemented Carbide Die 86 - 93HRA Hardness abrasion resistance

Performance characteristics

High hardness (86～93HRA, equivalent to 69～81HRC);
Good thermal hardness (up to 900～1000℃, keep 60HRC);
Good abrasion resistance.
Carbide cutting tools are 4 to 7 times faster than high-speed steel, and the tool life is 5 to 80 times higher. Manufacturing molds and measuring tools, the service life is 20 to 150 times higher than that of alloy tool steel. It can cut hard materials of about 50HRC.
However, cemented carbide is brittle and cannot be machined. It is difficult to make integral tools with complex shapes. Therefore, blades of different shapes are often made, which are installed on the tool body or mold body by welding, bonding, mechanical clamping, etc.

Our Product Series include cemented carbide turning & milling cutting tools with standard and non-standard; various kinds of wear-resisting, anti-crosion precision mould and structural parts; semifinishing and precision machining of cermet and non-cermet cutting tools.

In recent years, with decades of accumulated experience and knowledge and through unremitting efforts, we’ve developed high quality Gear Cutter Series, which including: Gear Hobs series, Shaper Cutters series, Shaving Cutter series etc.

We locate in Zhuzhou city, the land of cemented carbide in China. The company has precision production equipment from key raw materials and mixtures preparation, precision forming, atmosphere and pressure control sintering, grinding and coating, and has precision measuring instruments for international quality management standard. That is why the quality of AoHua gear cutter has even exceeded that of the original world-class brand.

AoHua Tools team will serve gear cutting tools with best quality, competitive price with best delivery for our valuable customers. We look forward to your continued interest in our gear cutting tools and wish all the best to you and your family.
