Product Features

Bit face shape selection:

1. Concave Face

The all-round application bit face specifically for medium hard and homogenerous rock formations. Good hole deviation control and good flushing capacity.

10inch DTH Drill Bit for Coal Mining with Heat Treatment and 254mm to 330mm Diameter

2. Convex Face

For high penetration rates in soft to medium-hard with low to medium air pressures. It is the most resistance to steel wash, and may reduce the load and wear on the gauge buttons, but poor hole deviation control.

3. Flat Face Bit

This kind of face shape is suitable for hard to very hard and abrasive rock formations in applications with high air pressures. Good penetration rates an resistance to steel wash.
