Commonly used rock drill bits

- Jan 03, 2019-

The cemented carbide bit is broken by the impact load generated by drilling pressure and self-rotation. In rock drilling, the drill bit withstands the impact load of high frequency, and is subjected to a variety of composite stresses such as torsion, bending, stretching and compression, and is subjected to wear and corrosion of working medium such as rock, rock powder and mineral water in the environment of high speed rotary collision.
