Our Alloy Steel DTH Drill Bits are made of high quality alloy steel
with advanced heat threatment to assure the good drilling
performance and long service life. They are widely used by our
customers all over the world.The DTH bits have various sizes and
styles ,For the most effective operation in various drilling
conditions, we offer flat face, concave, drop centre head designs.
1. according to China's mining conditions, to absorb the advanced
technology of domestic and foreign impactor and design and manufacture of the latest products.
2. reasonable selection of materials, advanced manufacturing
technology, quality assurance perfect.
3. has higher drilling speed.
4. can provide hardening treatment in order to prolong the service
life and reduce the cost of use.
5. single impact power is large, and the power consumption of
broken rock is low.
6. piston and bit weight to have the best momentum transfer.
7. the modern theory is adopted in the structural design, which
makes the stress wave duration longer, the stress amplitude is lower, and the piston life is long.
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.
