Bit Face Shape Selection:

1. Drop Center Bit

Ideal for high penetration rates in soft to medium hard, fissured rock formations, operating at low to medium air pressures, while ensuring maximum control over hole deviation.

2. Concave Face

An all-around solution perfect for medium hard and uniform rock formations, offering excellent hole deviation control and superior flushing capacity.

3. Convex Face

Designed for high penetration in soft to medium-hard rocks with low to medium air pressures. It offers robust resistance to steel wash, potentially reducing gauge button wear, though it provides limited hole deviation control.

4. Flat Face

Suited for hard to very hard, abrasive rock formations under high air pressure conditions. It offers good penetration rates and strong resistance to steel wash.

 Raw Material

Steel:

Crafted from first-class special alloy steel, providing high strength, heat resistance, and durability.

Carbide
Utilizing the finest tungsten carbides from China for superior performance.
Premium European tungsten carbide options are also available for enhanced quality.
