Description


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
