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.
