The tool is supplied with one motor/valve group chosen to suit the hole diameter; six motors are available, orbital type for high efficiency and long service life (the 20 cc motor for small diameters is a gear motor). Additional motor/valve groups are available separately. The drill rig is not included.

Six motor options from 20 cc to 315 cc
Motor power 9 kW at 38 L/min and 140 bar

Supplied in DOA's underwater version.

Hydraulic tools need a hydraulic power pack or a machine with a suitable hydraulic circuit (see oil flow and pressure in the technical data).
