Bit Face Shape Selection:

1. Drop Center Bit

Engineered for high penetration rates in softer to medium-hard, fissured formations. Ideal for low to medium air pressures, with excellent hole deviation control.

2. Concave Face

The versatile choice for medium-hard, homogeneous rock formations, offering excellent deviation control and flushing capabilities.

3. Convex Face

Designed for rapid penetration in softer to medium-hard formations at low to medium air pressures. Offers high resistance to steel wash, reducing wear on gauge buttons, though with limited deviation control.

4. Flat Face

Optimal for hard to extremely hard and abrasive formations, operating under high air pressures. Ensures robust penetration rates and resistance to steel wash.

 Raw Material

Steel:

Crafted from premium special alloy steel, delivering high strength, excellent heat resistance, and durability.

Carbide
Our products incorporate top-grade tungsten carbides sourced from China, renowned for their quality.
European tungsten carbide is also available, offering superior hardness and performance.
