Matching the insert to the job requirements is essential in achieving the desired results. Each of the following buttons is ideal for different ground conditions, abrasion levels, PSIs and penetration levels. In general, the larger the number of gauge buttons the better overall performance, especially in hard rock.

The Characteristics of High Air Pressure DTH Hammer with foot Valve.

1. Valveless air distribution.More Reliable
2. Simple design of the piston,long life
3. More efficient energy transfer,fasting drilling speed,lower air consumption and lower oil consumption
4. Fewer internal parts,simple structure,longer life,less failure 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

The Characteristics of High Air Pressure DTH Hammer without foot Valve.

1. Out of the trouble of foot valve fracture and expansion and contraction
2. Lower energy consumption and higher impact frequency.The drilling speed is 15%-30% higher than the one with foot valve
3. Simple Structure,reliable parts,long life,easy and cheap maintenance
4. Lower air and oil consumption.The oil consumption is about 10% lower than the one with foot valve
