Product Features & Description

Because of economy and powerful drilling capacity, down the hole hammer become an advanced drilling tool for drilling and mining industries. Down the hole hammers and drill bits are designed together to work in perfect unison, giving high penetration rates, long service life and low costs.

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

Applications

Suitable for high pressure drilling rigs and water well drilling.
Record breaking penetration in bench drilling and mining.
Ideal for Civil Engineering applications and mineral exploration.
Oil well drilling with lowest cost per foot drilled.
Maximizes efficiency for various compressor capacities (penetrate 15% to 30% faster).

Available Sizes

3" DTH Bits: DHD3.5, M30
