Product Features

Bit Face Shape Selection:

Concave Face: Ideal for medium-hard, homogeneous rock formations. Provides excellent hole deviation control and efficient flushing capacity.
Convex Face: Delivers high penetration rates in soft to medium-hard formations with low to medium air pressures. Offers superior resistance to steel wash while reducing load on gauge buttons, though with less hole deviation control.
Flat Face Bit: Designed for hard to very hard, abrasive rock formations in high air pressure applications. Combines good penetration rates with resistance to steel wash.
