hard rock drill bits,
air hammer drill bits
SP1480 Cemented carbide steel High air pressure DTH Drill Bits for DTH drilling
Face shape Features
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
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
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
The use of high quality steel and hard alloy as raw materials, through a special heat treatment process, ball tooth bit can reach under the hardness strong rock excavation, and to reduce the energy loss in the transmission process, tooth uniform force is not easy to drop off the teeth and teeth, so that impact the energy to focus on the rock to reach the purpose of high efficiency driving.
Widely used in mines, quarries, earthworks and other engineering drilling blasting hole, guardrail hole,mountain reinforcement, anchorage and other engineering holes, geothermal exploration hole, Well bore and other fields.
