DTH hammers are used for blast hole drilling and blasting, mainly applied in mining, marble quarry or well drilling and other construction projects.
DTH hammer drill bit used in geological exploration, coal mine, water conservancy and hydropower, highway, railway, bridge, construction and construction, etc.
Advantages:
New products are designed based on mining conditions, and improved by advanced technology from the global market.
Superior materials, advanced process, guaranteed quality.
Faster drilling rate.
Hardness can be enhanced to expand the lifespan of the hammer and lower the cost.
Huge impulse with low consumption of electricity.
The modern theory is adopted in the structural design, which makes the stress wave duration longer, the stress amplitudes lower, and the piston life longer.
Our products are made of alloy material, with wear-resistant drill buttons, stable drilling speed, high drilling efficiency, good diameter protection, and long service life of drill bits, which are higher than those of similar products.
