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.
