Bit Face Shape Selection:

1. Drop Center Bit

Ideal for high penetration rates in soft to medium-hard and fissured rock formations. It operates efficiently under low to medium air pressures and offers excellent hole deviation control.

2. Concave Face

A versatile choice for medium-hard and homogeneous rock formations, providing good hole deviation control and superior flushing capacity.

3. Convex Face

Designed for high penetration rates in soft to medium-hard formations with low to medium air pressures. This face shape is highly resistant to steel wash, reducing load and wear on gauge buttons, though it offers poorer hole deviation control.

4. Flat Face

Best suited for hard to very hard and abrasive rock formations, especially under high air pressures. This face shape ensures good penetration rates and resistance to steel wash.

 Raw Material

Steel:

Crafted from first-class special alloy steel, offering high strength, excellent heat resistance, and superior wearability.

Carbide
Premium tungsten carbides sourced from China ensure durability and performance.
Additionally, European tungsten carbide options are available for specialized needs.
