DTH bits
1. manufacture as your requirement
2. bit diameter, face shape
3. carbide button shape
4. number of air hole
Bit face shape selection:
1. Drop Center Bit
For high penetration rates in soft to medium hard and fissured rock
formations. Low to medium air pressures. Maximum hole deviation
control.
2. Concave Face
The all-round application bit face specifically for medium hard and
homogenerous rock formations. Good hole deviation control and good
flushing capacity.
3. 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.
4. Double Gauge Face
This kind of face shape is suitable for fast penetration rates in
medium to hard rock formations. Designed for high air pressures and
good resistance to steel wash step gauge bit.
5. 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.
