8'' QL80A DTH Hammer without Foot Valve Type for Qre Mining or Well Drilling
Product Advantages:
1.Avoid the problem happens on foot valve. Fracture,expansion and contraction
2.Lower air comsumption and higher impact frequency. 15-30% higher drilling efficiency than the bit with foot valve.
3.Simpler structure and less spare parts, makes easier & cheaper maintenance.
4.Heat-hardened spare parts,makes longer serving life and less problem.
5.Thread connection for top sub and drive chuck,makes easier disassembly

Face shape Features
Drop Center
For high penetration rates in soft to medium hard and fissured rock formations. Low to medium air pressures. Maximum hole deviation control.
Concave Face
The all-round application bit face special for medium hard and homogenerous rock formations. Good hole deviation control and good flushing capacity.
Convex Face
For high penetration rates in soft to medium-hard with low to medium air pressures. It is the most resistance to steel wash, and may reduce the load and wear on the gauge buttons, but poor hole deviation control.
Flat Face
This kind of face shape is suitable for very hard and abrasive rock formations in applications with high air pressures. Good penetration rates an resistance to steel wash.
Double Gauge Face
This kind of face shape is suitable for fast penetration rates in medium to hard rock formations. Designed for high air pressures and good resistance to steel wash step gauge bit.
Product application
At present, DTH drilling tool is widely used in underground mining, quarries, hydraulic and Hydro-Power Engineering, water well drilling, Mineral exploration, anchoring hole drilling, geothermal engineering, Subway excavation, another civil engineering.
DTH is one of the most efficient ways of drilling rock, using a rapid hammer action to break the rock into sizeable chips which are then evacuated from the bore hole by the air exhausted from the DTH Hammer. The technique provides fast drilling of accurately aligned, straight and clean holes in most ground conditions.
