Product Features

Bit Face Shape Selection:

Concave Face: Ideal for medium-hard, homogeneous rock formations. Provides excellent hole deviation control and flushing capacity.
Convex Face: Delivers high penetration rates in soft to medium-hard formations with low to medium air pressures. Resistant to steel wash but offers poor hole deviation control.
Flat Face Bit: Designed for hard to very hard, abrasive rock formations with high air pressures. Offers good penetration rates and steel wash resistance.
