Shank COP64 Down The Hole Hammer
6" DTH Hammer for Mining with Foot Valve Compatible with Bit Shank Cop64/DHD360
DTH hammer is a percussion system driving a piston inside hammer body with up and donw 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.More efficient energy transfer, faster drilling speed, lower air and oil consumption.
2.Valveless air distribution. More reliable.
3.Simple design of the piston, long life.
4.Easy to disassemble because the top sub, the drive chuck and the external cylinder are connected by multi-step thread.
5.Fewer internal parts, simple structure, longer life, less failure and easier to maintain because all the parts are heat treated.
Face shape Features
For high penetration rates in soft to medium hard and fissured rock formations. Low to medium air pressures. Maximum hole deviation control.
The all-round application bit face special for medium hard and homogenerous rock formations. Good hole deviation control and good flushing capacity.
For high penetration rates in soft to medium-hard with low to medium air pressures. It is the most resistance to steel wash, and may reduce the load and wear on the gauge buttons, but poor hole deviation control.
This kind of face shape is suitable for very hard and abrasive rock formations in applications with high air pressures. Good penetration rates an resistance to steel wash.
Double Gauge Face
This kind of face shape is suitable for fast penetration rates in medium to hard rock formations. Designed for high air pressures and good resistance to steel wash step gauge bit.
At present, DTH drilling tool is 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.
DTH is one of the most efficient ways of drilling rock, using a rapid hammer action to break the rock into sizeable chips which are then evacuated from the bore hole by the air exhausted from the DTH Hammer. The technique provides fast drilling of accurately aligned, straight and clean holes in most ground conditions.
