- The main features are as following:
- compatibale with the bits of SD series
- simple pison structure increases its lifetime
- adopt valveless air distribution. simple structure makes it easy for disassembiy
- with faster drilling speed and less power consumption
- when required to increase deslagging,holes can be added on reverse valve
- adopt fine alloy steel and apply hardening treatment on the spare parts,which prolongs DTH hammer lifetime and liftsvreliability
