BR1 DTH Hammer
DTH hammer was designed by international advanced high-tech theory, which makes the hammer have better energy transduction, faster working speed and less air consumption.
- The pressure are between 0.7 MPa and 1.75 MPa.
- Valveless hammers.
- Simple structure, esily to assemble and to disassemble, long lifespan.
- Higher impulse and faster drilling rate.
- Lower air consumption and lower oil consumption. A hole can be drilled on the check valve to provide more efficient cuttings discharge.
- Especially suitable for quarrying.
