DHD3.5 DHD340 DHD350 DHD360 DHD380 DHD1120 DHD COP Rock Drill Bit

DTH drilling is a percussion system driving a piston inside hammer body with up and down motion by compressed air and transmitting an intensive percussion energy to the bit to enable the drilling by crushing the rock. Drilling method by DTH hammer exerts high drilling performance especially for drilling hard rock and contributes for shortening work schedule. Hence, this method is widely utilized for foundation work, landslide prevention work, quarrying services, marine civil work, etc.
1.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.
6. Item number includes:
COP32, IR3.5/COP34, DHD340/COP44, DHD350R/COP54,
DHD360/COP64, DHD380/COP84, DHD1120...
