drill accessory tool high pressure drill bit button thread button bit hard rock drilling 110 cop44 dth hammer bits

Our tools are widelyused 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”-32”(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.

Advantages:

1.Out of the throuble 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.

Product Overview












Carbide button shape selection:
1. Domed/Round Button
Domed/Round Buttons are usually used as gauge buttons of DTH Bits, suitable for every abrasive and very hard formations.
2. Parabolic/Semi-Ballistic Buttons
Parabolic Buttons are usually used as gauge buttons and front buttons of DTH Bits, suitable for medium abrasive and hard formations.
3. Ballistic Button
Ballistic Buttons are usually used as front buttons of DTH Bits, suitable for medium abrasive and mesium hard formations. They can also be used as gauge buttons if the rock is soft.
4. Sharp Button
Sharp Buttons are usually used as front buttons of DTH Bits for soft formations where fast penetration rates are possible.
5. Flat Button
Flat buttons are usually used as protection buttons to reduce wear on rubbing surfaces of DTH bits.
