Key specifications

How to use

Mount the arbor by threading the M16 connection into the hollow core drill according to the core bit manufacturer's instructions, then insert the 12 mm hex shank into the drill's chuck or adapter. Ensure the pilot drill is centered and secured before starting. Operate the rotary or impact drill at speeds and feed rates recommended for the chosen core bit and the material being drilled, applying steady pressure and cooling where appropriate.

Recommendations

Check that the M16 thread matches the core bit and that your drill accepts a 12 mm hex shank. Use appropriate personal protective equipment, maintain correct drilling speed for the material, and employ water cooling or dust extraction when drilling masonry or concrete to extend tool life and improve results.
