DTH Hammer – Bit With Foot Valve

The Characteristics Of High Air Pressure DTH Hammer available for the bit with foot valve

It is a kind of valveless high air pressure DTH Hammer available for the bit with foot valve.

It has the following characteristics:

• Valveless air distribution. More reliable.

• Simple design of the piston, long life.

• More efficient energy transfer, faster drilling speed, lower air consumption and lower oil

• Fewer internal parts, simple structure, longer life, less failure and easier to maintain because all the parts are heat treated

  Robust & durable performance

  Easy to disassemble because the top sub, the drive chuck and the external cylinder and connected by multi-step thread

DTH Hammer – Bit Without Foot Valve

The Characteristics Of High Air Pressure DTH Hammer available for the bit without foot valve

It is a kind of high air pressure DTH Hammer without foot valve, our newest design. It is also one of the most advanced DTH Hammers in the world.

It has the following characteristics:

• Out of the trouble of foot valve fracture, expansion and contraction.

• Lower energy consumption and higher impact frequency. The drilling speed is 15-30% higher than one with a foot valve.

• Simple structure, reliable parts, long life, easy and cheap maintenance.

• Lower air and oil consumption. The oil consumption is about 10% lower than one with a foot valve.
