DTH bit is the tool cutting rocks, and subject to severe stress
from the striking piston as well as from the abrasive cuttings
passing the bit at high velocity. When selecting the right bit for
optimum performance you have to balance penetration against bit
life. On occasion you can successfully sacrifice bit life for
penetration, remember the rule of thumb that states that a 10%
increase in penetration covers at least a 20% loss in bit life.
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.
Advantage of Our DTH drill bits
1. Anti-stuck protection can aoid the ruined of the motor and the
damage of reducer
2. high efficiency
3. low cost
4. stable performance
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.
