API 4 1/2" Reg Connection Thread 8inch DTH Hammer for High Air Pressure Rock Drilling -SD8 M80 Ql80 DHD380 Cop84

8inch High Air Pressure DTH Hammer With Foot Valve compatible with bit shank QL80 / COP84 / SD8 / M80 / DHD380 / CD85

Advantages:
1. Valve air distribution. More reliable.
2. Simple design of the piston, long life.
3. More efficient energy transfer, faster drilling speed, low air consumption and low 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-sted thread.

The advantages of hammers without foot valve against with foot valve:
1. No more worries on the foot valve breakage or distortion or expansion due to the abrasion or high tempreture.
2. Higher impact rate, lower energy consumption, around 15-30% higher drill speed than the one with foot valve
3. Remain simple design, and reliable parts, long life, easy and cheap maintenance.
4. Lower air and oil consumption, oil consumption can be around 10% lower than the one with foot valve.
5. Strongly recommond.
