Product 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.

High Efficiency: Deliver maximum energy to drilling bit, fast drilling speed and low air consumption due to special inner structure designed according to rock drilling theory.
Durability: Smooth performance and long service life due to high quality alloy steel materials and advanced processing technology.
Low Maintenance: Simple, reliable, and easy to assemble/disassemble inner structure reduces problem rates.
Easy Operation: Easy to depart bit from hammer due to multihead thread connecting chuck and cylinder.
Versatility: Interchangeable with DTH bit and drill pipe. Suitable for high pressure drilling rigs, water well drilling, bench drilling, and mineral exploration.

Available Bit Sizes:

3″ DTH Bits: DHD3.5, M30
4″ DTH Bits: DHD340, SD4, QL40, M40
5″ DTH Bits: DHD350, SD5, QL50, M50
