How to use

Select a suitable arbor and secure the hole saw to the drill according to the arbor manufacturer’s instructions. Mark the center point of the hole on the workpiece and clamp the workpiece to prevent movement. Start drilling at low speed to establish the pilot position, then increase speed and apply steady, even pressure. Withdraw the tool periodically to clear chips and reduce heat build-up. After cutting, clean any remaining debris from the hole edges to improve fit for pipes or fittings.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. For best results on finished surfaces, place masking tape over the cut location to reduce splintering and finish the hole edge with light sanding if necessary. Avoid excessive feed pressure and allow the drill to do the work to prolong the tool life.
