RC545 DTH Hammers Drill Bit For Mining Water Well Drilling And
Blasting DTH Bits
KSQ DTH hammer button bits include high air pressure and low air
pressure two series,with advanced design concept, better
wear-resistance,better impact-resistance, higher drilling speed,
longer service life, widely used in large-scale open pit mining,
quarry and other large-scale construction projects.

High Air pressure DTH hammer
1. valveless air distribution. More reliable.
2. simple design of the piston, long life.
3. More efficient energy transfer, faster drilling speed, lower air
consumption and lower oil consumption.
4. fewer internal parts, simple structure, longer life, less
failure and easier to maintain becayse all the parts are heat
treated.
5. It is easy to disassemble because the top sub, the drive chuck
and the external cylinder are connected by multi-step thread.
