Bit Face Shape Selection:

1. Drop Center Bit

Ideal for high penetration rates in soft to medium-hard fissured rock formations. Suitable for low to medium air pressures with excellent hole deviation control.

2. Concave Face

Perfect for medium hard and homogeneous rock formations, offering excellent hole deviation control and efficient flushing capacity.

3. Convex Face

Best suited for high penetration in soft to medium-hard rocks. It withstands steel wash effectively, potentially reducing gauge button wear, though it offers less hole deviation control.

4. Flat Face

Engineered for hard to very hard, abrasive rocks, this shape excels in high air pressure applications, offering robust penetration rates and resistance to steel wash.

 Raw Material

Steel:

Crafted from premium special alloy steel, our tools boast high strength, exceptional heat resistance, and wearability.

Carbide
Our products commonly utilize top-quality tungsten carbides sourced from China, known for their performance.
For those seeking alternatives, we also offer tungsten carbide sourced from Europe, meeting diverse needs.
