Key specifications

How to use

Fit the hole saw onto the cordless screwdriver using the appropriate hex or SDS shank, secure the 6 mm pilot drill in place and position the pilot at the intended drilling point. Apply steady, moderate pressure and run the driver at an appropriate speed for the material being cut. Allow the pilot drill to centre the saw, progress the cut while clearing chips as needed, and withdraw periodically if required to remove debris and prevent overheating. After cutting, clean the hole and remove the pilot bit.

Recommendations

Use appropriate personal protective equipment (safety glasses, gloves and dust mask) and select a suitable driver speed for the material. For masonry or aerated concrete, use lower speed and increased feed pressure; for wood and plastics, a higher speed with controlled feed gives cleaner cuts. Ensure the shank type matches your cordless screwdriver and check compatibility before use.
