5-6 inch High Air Pressure DTH Bit

Applications:

DTH drill 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 drill rod and hammer, independent of high axial thrust, no limit of drilling depth, low cost of devices and easiness to maintain.

Advantage of High Air Pressure DTH Bit:

The longer life of the drill: 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 the drilling.

The drilling speed is stable: the bit is scraped and cut to break the rock.

Good Performance: the New Diamond 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, sandstoneand 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.
