SD Series High Air Pressure DTH Button Bits from 2'' to 15'' for
Mining
Product description
The DTH system is easy and quick to adapt to a directional drill
and is considered one of the best and most effective methods to
drill high-quality holes that are stable and straight. It can be
done on both hard and soft rock and is extensively used in the
construction, oil and gas, and water well industries.
1. High grade tungsten carbide inserts
2. Bit bodies manufactured from high grade steel and processed
using state-of-the-art CNC machinery and heat treatment
3. Recommended for eliminating hole deviation
4. Widely used drifting and tunneling
5. Bit face design is ideal for medium-hard to hard abrasive rock

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.
