Bit Face Shape Selection:

1. Drop Center Bit

Tailored for high penetration in soft to medium-hard, fissured rock formations. Ideal for low to medium air pressures, ensuring maximum control over hole deviation.

2. Concave Face

Optimal for medium-hard and homogeneous rock formations. Provides excellent hole deviation control with superior flushing capacity.

3. Convex Face

For enhanced penetration rates in soft to medium-hard conditions with low to medium air pressures. Offers maximum resistance to steel wash, reducing load and wear on gauge buttons, though with limited hole deviation control.

4. Flat Face

Ideal for hard to very hard, abrasive rock formations with high air pressures. Delivers remarkable penetration rates and superb resistance to steel wash.

 Raw Material

Steel:
