190mm DTH Drill Bit overview

Product Advantages:

1. The service life of the DTH bit is increased by more than 6 times;
2. The overall tool cost of the operation decreased by more than 30%;
3. The production efficiency of the operation is increased by more than 20%;
4. It can better maintain the quality of the well hole;
5. Make the target application that was impossible to complete once become possible;
6. Reduce the frequency of tool replacement and reduce the labor intensity of workers.

Design Features

1. Computer analysis and laboratory trials have been used to optimize the number of buttons as well as their size and positioning throughout the bit front.
2. Carbide has been carefully designed to minimize the risk of button loss and button failure
3. The design of the bit body and the frontal sludge grooves provides uniform flushing with reduces steel wash on both bit and the hammer.
4. Material processes and multiple heat treatment have focussed on achieving maximum resistance to fatigue failure.
5. Special bit designs such as Concave and Convex/CB are available on request.

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.
