Product Description

Wholesales Down The Hole Low/High Air/Pressure 3"4"5"6"8" 10" DTH bit /DTH hammer

Construction machinery parts 3"4"5"6"8" DHD/Ql/Cop/Misson/SD DTH Hammer and DTH steel Bits for Mining/Water well Drilling

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"-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.

Product Overview
The characteristics of High Air pressure DTH Hammer with foot valve

Valve air distribution, more reliable.
Simple design of the poston, long life.
More Efficient energy transfer, faster drilling speed, lower air consumption and low oil consumption.
Fewer internal parts, simple structure, longer life, less failure and easier to maintain because all the parts are heat treated.
Easy to disassemble because the top sub, the drive chuck and the external cylinder are connected by multi-step thread.

The characteristics of High Air pressure DTH Hammer without foot valve

Out of the trouble of foot valve fracture and expansion and contraction.
Lower energy consumption and higer impact frequency. The drilling speed is 15% to 30% higher than the one with foot valve.
Simple structure, reliable parts, long life, easy and cheap maintenance.
Lower air and oil consumption. The oil consumption is about 10% lower than the one with foot valve.

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.
