KRUPP Drifter HB48

• Especially developed for overburden drilling, drive drilling, threaded self-drilling anchors and micropiles.

• Casing diameter up to 177 mm (7 inch) and threaded hollow bars up to a diameter of 103 mm (4 inch).

• The standard built-in rubber damping mechanism improves retraction of casings and rods and avoids blank impacts.

• Optional: electric, hydraulic or manual changeover for the rotary drive speed and for the percussion mechanism frequency.

• Options: external flushing head, central lubrication system and integrated RPM sensor.

Compact design – the ideal drifter (hammer drill) for mid-size and larger drill rigs and excavator mounted drill masts.
