How to use

Securely attach the hole saw to a compatible arbor or drill with an M14/HEX connection. Mark the centre of the hole and start drilling at low speed to create a guide. Increase speed as appropriate for the workpiece material while applying steady, moderate pressure. Use cutting fluid or cooling when drilling metal to extend tool life. After cutting, retract the saw and remove any core material from the cup.

Usage recommendations

For best results, use with a drill capable of stable RPM control, apply cutting lubricant when working with steels, and avoid excessive side force. Inspect the saw before use and replace if teeth show significant wear or damage.
