Key Features

Suction Centering Guide

This standard equipment device attaches to the workpiece by suction cup, and the rollers guide the core bit for accurate hole placement. It can connect to a vacuum for dry drilling, and also has a drain tube for wet drilling slurry.

Optional Pressurized Water Tank

The water tank allows autonomous water supply. The flow regulator enables control and fine tuning of the water.

Optional Water Supply Kit

The water supply kit allows wet drilling when there is an external supply of water

Quick-Release Coupling System

The quick-release collar and bit adapters allow quick and easy clearing of the cores which tend to stick in the bit after drilling. The tool comes standard with both G ½" BSP and M14 bit adapters.

Ergonomic Main Handle

The shape of the main handle allows the operator to naturally hold the tool straight, for best work results.
