Product Description 

 It has the following advantages,
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.
