The Characteristics of High Air Pressure DTH Hammer
1. Valve air distribution, more reliable.
2. Simple design of the piston, long working life
3. More energy transfer, faster drilling speed, lower air and oil consumption.
4. Fewer internal parts, simple structure, longer service life, lower failure rate and easier to maintain because all the parts are heat treated.
5. Easy to disassemble because the top sub, the drive chuck and the external cylinder are connected by multi-step thread.










Bit Face Selection
Drop Center For high penetration rates in soft to medium hard and fissured rock formations. Low to medium air pressures. Maximum hole deviation control.

Concave Face The all-round application bit face special for medium hard and homo-generous 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 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.

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