Six Star Hardmetal carbide button have good wear-resistant and a longer service life.

Six Star Hardmetal carbide buttons have good wear-resistant and a longer service life.

1. drill bits have long service life: with the unique proprietary technology,our cemented carbide drill bits strength ≥2800N,hardness(HRA)≥92.

2. drill bit button do not break easily: using high strength carbide chisel tool stell, and strict technology for heating processing, our drill bit button have higher strength.

3. full type, our drill bit can meet the request of mining with different hardness of rock
