203mm DTH Drill Bit overview

Face shape Features

Concave Face

1. Capable of drilling straighter holes in medium to hard rock which is broken or less consolidated

2. Offers high penetration rate in the above stated rock conditions

3. Has excellent air flushing characteristics

4. Predominant face style for majority of drilling conditions

Flat Face

1. Have a superior performance in hard, abrasive and broken rock conditions

2. They however have a slower penetration rate in comparison to a concave face bit

Convex Face

1. This face has been designed to offer high penetration rate in soft rock such as shale, limestone etc

2. They are recognized for having excellent capability for drilling into moderately consolidated rock conditions

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.
