• Deliver maximum energy to drilling bit, fast drilling speed and low air consumption due to the special inner structure of DTH hammer designed according to newest rock drilling theory.
• Smooth performance and long service life of DTH hammer due to high quality alloy steel materials and advanced processing technology adapted.
• Low problem rate and easy to maintenance due to simple, reliable and easy assemble and disassemble inner structure of hammer.
• Easy to depart bit from hammer due to multi—head thread connecting chuck and cylinder of hammer.
• Interchangeable with DTH bit and drill pipe.

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