Bit Face Shape Selection:

1. Drop Center Bit

Perfect for high penetration rates in soft to medium-hard and fissured rock formations. Operates optimally under low to medium air pressures and provides excellent hole deviation control.

2. Concave Face

This versatile bit face is ideal for medium-hard and uniform rock formations, offering good hole deviation control and excellent flushing capacity, making it a go-to choice for various applications.

3. Convex Face

Engineered for high penetration rates in softer terrains, this face shape resists steel wash effectively and minimizes wear on gauge buttons, though it may offer less hole deviation control.

4. Flat Face

Designed for the toughest and most abrasive rock formations, it performs exceptionally under high air pressures, offering impressive penetration rates and resistance to steel wash.

 Raw Material
