Down the hole dth drilling hammer bit manufacturer
1.The longer life of the drill: the alloy material, with longer using life which better than the similar products;
2.High Dilling Eficiency: the dril buttons is wear-resistant, so that the drill can always keep sharp thus greatly improving the speed of the drllng.
3.The driling 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 drling), compared with normal bit,especially drilling in 6-8 grade rock the effect is particularly significant.
