Product Detailed
1.efficient energy transfer 2.faster drilling speed 3.lower oil consumption 4.longer life,working reliable

high air dth hammer1.efficient energy transfer2.faster drilling speed3.lower oil consumption4.longer life,less failure

It has the following advantages:

1 Valveless air distribution. More reliable.

2 Simple design of the piston, long life.

3 More efficient energy transfer, faster 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.
