Advantages of MSD down the hole bits:

The longer life of the drill: the alloy material, with longer using life which better than the 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 drilling.

The drilling speed is stable: the bit is scraped and cut to break the rock.

Good performance: MSD bit has strong wear resistance, good diameter protection and can  make the cutting teeth be used efficiently, can drill more meters.

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 drillability of rock, hard rock drilling), compared with normal bit, especially drilling in 6-8 grade rock the effect is particularly significant.


The Application of DTH hammer:

MSD DTH drill bit is mainly used in geological exploration, coal mine, water conservancy and hydropower, highway, railway, bridge, and construction etc.
