How to use

Mount the hole saw on a compatible TWIST arbor or drill adapter according to the arbor manufacturer’s instructions. Secure the workpiece and mark the center point, then start drilling at low speed to establish the cut. Apply steady, even pressure and increase speed as appropriate for the material. After cutting, clear debris and inspect the hole for clean edges.

Recommendations

Use appropriate personal protective equipment (safety glasses and gloves). For best results in wood, use moderate drill speed and avoid excessive feed pressure; in plastic, reduce speed to minimize melting. Ensure the arbor and drill are suitable for the 105 mm hole saw and the required cutting depth.
