Bit Face Shape Selection:

Center Drop Bit:

For high penetration rates in soft to medium hard and fissured rock formations. Low to medium air pressure.

Maximum hole deviation control.

Concave Face

The all-around application bit face specifically for medium hard and homogenerous rock formations.

Good hole deviation control and good flushing capacity.

Convex Face

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

Double Gauge Face

This kind of face shape is suitable for fast penetration rates in medium to hard rock formations. Designed for high air pressure and good resistance to steel wash step gauge bit.

Flat Face Bit

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

Competitive Advantage

In DTH drilling, the rock drilling bit is a continuation of the shank, which the rock drill piston strikes directly. Since the piston is in direct contact with the drill bit, little energy is lost. This gives DTH drilling a nearly constant penetration rate regardless of hole length.
