Product Advantages:
1.Five basic dth drill bit designs: Flat front, Convex, Speed,
Concave. All shapes for all types of rock of hard, soft or
abrasive.
2.Deliver maximum energy to dth drilling bit, fast drilling speed
and low air consumption due to inner structure of HD series DTH
hammer designed according to newest rock drilling theory.
3.Smooth performance and long service life of DTH drill bits due to
high quality alloy steel materials and advanced processing
technology adapted.
4.Low problem rate and easy to maintenance due to simple , reliable
and easy assemble and disassemble inner structure of DTH drill
bits.
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.
