Product description

Tungsten Carbide Chisel insert for Mining

tungsten carbide mining bit has superior wear resistance and impact toughness, and similar products with higher speed of drilling and digging.Series of ball tooth bit passivation using cycle is long, not to grind the life span of about the same diameter RenPian grinding head drill bit 5-6 times of life, is beneficial to save auxiliary working hours, physical labor and reduce workers to speed up the project.
