1.The longer life of the drill
the alloy material, with longer using life which better than the similar products.
 
2.High Drilling Efficiency
the drill buttons is wear-resistant, so that the drill can always keep sharp, thus greatly improving the speed of the drilling.
 
3.The drilling speed is stable
the bit is scraped and cut to break the rock.
 
4.Good Performance
the New Diamond bit has strong wear resistance, good diameter protection and can make the cutting teeth be used efficiently.
 
5.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.
