High Quality 203mm High Pressure Down-the- hole DTH Drill Bit For
Rock Mining
Product description
The life of the DTH bit depends on the material and technology of
the bit. The SOLLROC bit is made of the most efficient high quality
alloy steel.
Use quality forged steel, heat treatment and shot peening to
provide a durable and reliable balance of strength and toughness.
Product Advantages:
1) Widely used in metal mine, quarry, tunneling,
hydro-electricalengineering and so on.
2) Higher drilling efficiency.
3) Longer service life.
4) Better wear-resistance and impact-resistance.
5) Easier bit-back performance.

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.
