6 Inch Ql60 Down Hole Hammer Faster Drilling Speed With Low Air / Oil Consumption
6 Inch QL60 DTH hammer Low Air Consumption And Lower Oil Consumption
Features:
- Valveless operation to maximize energy output, provide efficient air utilitzation and reduce service requirements
- Extra air-flow system allows for better hole cleaning in troublesome holes
- Reversible hardened wear sleeve for optimum wear resistance even in the most abrasive conditions
- Multi-start threads on back head and chuck ensure easy coupling/uncoupling of hammer
- Unique internal mount system gives positive make-up and eliminates the need for wear shims and special assembly tools
- All critical internal components are heat treatedunder strict control to maximize tool longevity
- An overall cost-effective and user-friendly tool for use in the most demanding conditions
The Characteristics of High Air Pressure DTH Hammers With Foot Valve:
It is a kind of valveless high air pressure DTH hammer with foot valve. It has the following advantages:
The main features are as following:
1. Valveless air distribution, more reliable.
2. Simple design of the piston. Long life span.
3. More efficient energy transfer, faster drilling speed, low air consumption and lower oil consumption.
4. Fewer internal parts, simple structure, long life span, 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 multiple steps thread.

The Characteristics of High Air Pressure DTH Hammers Without Foot Valve:
It is a kind of high air pressure DTH hammer without foot valve, and it is our newest design. It is also one of the most advanced DTH hammers in the world.
It has the following advantages:
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 span, easy and cheap maintenance.
4. Lower air and oil consumption. The oil consumption is about 10% lower than the one with foot valve.
