Description

AK 46 is a hydraulic core drill for hand-held use or on a drill rig, in two configurations: AK 46 S for holes Ø 30–100 mm and AK 46 G for Ø 80–160 mm. Hydraulic drive cannot cause electric shocks and works fully submerged, with no vibration or noise, an excellent weight-to-power ratio and a motor that is not damaged by prolonged stalling or overload.

Safety valve cuts rotation automatically if the core bit jams
ON/OFF trigger with lock-on button for drill-rig use
Level gauge for straight vertical or horizontal holes
Ergal and stainless steel construction
Adjustable back handle to push with chest or knee; long side handle

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).
