> Drifter Series

MTB hydraulic drifters are designed for drilling holes on rock and stone surfaces. The dust produced inside the hole during drilling is carried outside with the carrier machine's compressor line.

DRF rock drifters are composed of flushing parts, rotation device, and hammering device.

Impact energy efficiency has been improved by increasing the impact frequency, which prolonged the lifetime of the parts. In addition, the automatic pressure regulator is provided to adjust the pressure to meet the various rock properties.

DRF Drifter is used for; drilling holes for explosion preparations at mines and mounting steel construction on the wall of tunnel constructions.

DRF 3 in the MTB hydraulic drifter series is 210 kg and manufactured to have 0-220 blow frequency and 60% maximum torque power.
