How to use

Secure the hole saw to an angle grinder using the M14 holding thread according to the grinder manufacturer's instructions. Mark the drilling position on the workpiece, start the grinder at low speed to establish the cut, then increase speed as appropriate for the material. Apply steady, moderate pressure and avoid forcing the tool. The product is intended for dry drilling at high speed without additional coolant.

Recommendations

When working with brittle or polished surfaces such as tiles or marble, support the workpiece to avoid chipping and use a steady hand to maintain perpendicular alignment. Allow the tool to cool between prolonged cuts and replace the hole saw if diamond segments show significant wear.
