Bit Face Shape Selection:

1. Drop Center Bit

Engineered for rapid penetration in soft to medium-hard, fissured rock formations. Optimal for low to medium air pressures with maximum hole deviation control.

2. Concave Face

The versatile choice for medium-hard and uniform rock formations. Offers precise hole deviation control and excellent flushing capacity.

3. Convex Face

For swift penetration in softer to medium-hard formations under low to medium air pressures. Offers resistance to steel wash, reducing load and wear on gauge buttons, though with reduced hole deviation control.

4. Flat Face

Ideal for tackling hard to extremely hard and abrasive rock formations, especially under high air pressures. Ensures efficient penetration and robust resistance to steel wash.

 Raw Material

Steel:

Premium special alloy steel: Boasting exceptional strength, heat resistance, and wearability for reliable performance.

Carbide
Utilizes top-grade tungsten carbides from China, ensuring consistent quality and performance.
Also available: European tungsten carbide, offering a premium alternative for specialized needs.
