Product Description
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:
The longer life of the drill: the alloy material, with longer use life which is better than similar products;
High Drilling Efficiency: the drill buttons are wear-resistant so that the drill can always keep sharp, thus greatly improving the speed of the drilling.
The drilling speed is stable: the bit is scraped and cut to break the rock.
Good Performance: the drill bit has strong wear resistance, good Diameter protection, and can make the cutting teeth be used efficiently.
The use of a wide range: the practice proves that the bit is suitable for carbonate rock, limestone, chalk, clay rock, siltstone, sandstone, and other soft and hard (9-grade drill ability of rock, hard rock drilling), compared with normal bit, especially drilling in 6-8 grade rock the effect is particularly significant.
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.
