Key specifications

How to use

Fit the hole saw to a compatible arbor and secure the arbor in the drill chuck. Mark the center of the desired hole and, if available, use the pilot bit to position the saw. Start drilling at low speed to establish the cut, then increase speed moderately while maintaining firm, even pressure. Withdraw the saw periodically to clear chips and prevent clogging. After cutting, smooth the edge if required using sandpaper or a file.

Recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. For best results, secure workpieces firmly and avoid excessive feed force; allow the tool to do the cutting. When working with plastics, use reduced speed to prevent melting. Ensure the arbor and pilot bit are compatible and in good condition before use.
