DTH bits are widely used in underground mining, quarries, hydraulic and hydro-power engineering, water well drilling, Mineral exploration,anchoring hole drilling, geothermal engineering, subway excavation,another civil engineering.
It has the advantage of high flatness, smooth hole wall, high rigid of drlll rod and hammer, independent of high axial thrust, no limit of drilling depth,low cost of devices and easiness to maintain.
The Longer Life of Drill Bit: the alloy material, with longer using life which better than the similar products;
High Drilling Efficiency: the drill buttons is wear-resistant, so that the drill can always keep sharp, thus greatly improving the speed of drilling
The Drilling Speed is stable: the DTH drill bit has strong wear resistance, good diameter protection and can make the cutting teeth be used efficiently.
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 (Rock formations below level 9), compared with normal bit, especially drilling in level.Compared with ordinary drill bits, the effect is particularly significant, especially when drilling into rock formations of level 6-8.
