As specialist manufacturer and provider of DTH drilling tools, hereby we recommend our newest generation DTH hammer which is improved by absorbing art technology, selecting superior alloy steel and robust design. It is proved by more than thousands times of test that our newest DTH hammer has longer life ,  lower air consumptionand 15% higher penetration speed compared the conventional DTH hammer in the market. And we are manufacturing the DTH bits with various shanks so they can be compatible with different DTH hammers.

1.CIR series Low air pressure DTH hammer includes: CIR55, CIR65, CIR70, CIR80, CIR 90, CIR110, CIR110W, CIR150, CIR170, CIR200W etc.

2.J series Low air pressure DTH hammer includes: J60C, J70C, J80B, J100B, J150B, J170B, J200B


R.C.(Reverse Circulation) hammmers

1.R.C. hammers includes:RC45,RC55,RC65,PR52 etc.


High air pressure DTH hammer:
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.


DTH bit is the tool cutting rock. DTH bits are made of superior quality alloy steel which is made by Timken in U.S. Besides, all our DTH bits are using the brand "Element Six" T.C carbide which provides (the T.C buttons) for Boart Longyear. In addition art manufacturing technology makes our DTH bits with higher and more reliable quality.
