Down The Hole Bits
Advantages of new diamond dive drilling
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.
