The D Miningwell high pressure drill bit is mainly used in geological exploration, coal mine, water conservancy and hydropower, highway, railway, bridge, construction and construction, etc.

Advantages Of D Miningwell high pressure drill bit:
1.The longer life of the bit: 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 D Miningwell high pressure drill 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.
