High Pressure DTH Hammer Tools – Water Well Drilling Bits Price
D Miningwell’s down-the-hole drill bits are made of alloy steel and advanced heat-treated high-quality alloy steel to ensure good drilling performance and long service life. Widely used by customers all over the world.
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.
