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.
Deliver maximum energy to drilling bit, fast drilling speed and low air consumption.
Smooth performance and long service life due to high quality alloy steel materials.
Low problem rate and easy to maintenance due to simple, reliable inner structure.
Easy to depart bit from hammer due to multihead thread connecting chuck.
Suitable for high pressure drilling, water well drilling, and mining exploration.
Penetrate 15% to 30% faster than standard tools.
