2. Carbide grade options for long life in challenging applications
3. Face designs to maximize penetration rate and tool life
4. Optimized flushing designs to aid in cuttings removal and reduce wea

 

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.
