Tungsten Carbide Rock Drill Bit DTH Hammer Button Bit

Our tools are widely used in different drilling applications including mining, quarrying, water well drilling, geotechnical industries and etc.

In DTH drilling, the rock drilling bit is a continuation of the shank, which the rock drill piston strikes directly. Since the piston is in direct contact with the drill bit, little energy is lost. This gives DTH drilling a nearly constant penetration rate regardless of hole length.

DTH Hammer Types coverage: DHD/COP/HD/IR/TD/COPROD/QL/SD/Mission/Numa/Mach etc.DTH Bit Size range: 2”-24”(76-775mm)

1.High air pressure DTH hammer size from 3" to 12"(76mm-304mm) 2.Shank types including COP, QL,DHD, MISSION,HD,IR, SD,TD, etc. 3.Connect Thread : API 2 3/8" , API 3 1/2 , Reg-6 5/8"Reg etc.

4 Low air pressure DTH hammer includes CR series: CR90, CR110, CR150, etc.

5 Middle air pressure DTH hammer includes CBR series: CBR1, CBR2, CBR3, etc.

1.Out of the trouble of foot valve fracture and expansion and contraction.

2.Lower energy consumption and higher impact frequency. The drilling speed is 15%-30% higher than the one with foot valve.

3.Simple structure, reliable parts, long life, easy and cheap maintenance.

4.Lower air and oil consumption. The oil consumption is about 10% lower than the one with foot valve.

Drilling and drilling blasting holes, landslide protection, dam site reinforcement and anchoring holes, ground heat source air conditioning, hydrology, water well holes and other fields in mines, quarries, road construction and other projects。
