Wear Resistant DTH Hammer Bits Stable Drilling Speed For Quarrying

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...
