Product Description

Drill pipes that are used in applications such as DTH/ DTHR/ DR basically comprise of a steel pipe with a pin at one end and a box on the other. The job of the drill pipe is to transmit rotational torque and thrust from the drill rig rotary head to down hole drilling tools. 

Compatible with the bits of COP/DHD/SD/QL/MISSION series

☆Compatible with the bits of cop/DHD series

☆Simple piston structure increases it's lifetime

☆Adopt valveless air distribution,simple structure makes it easy for dis-assembly

☆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 lifts reliability.
