Installation & Operation

1. Mount the hole saw securely on compatible arbor with appropriate shank size for your drill or drill press.
2. Mark the cutting location and ensure workpiece is properly secured with adequate backing support.
3. Start drilling at low speed to establish the cut, then increase to optimal cutting speed for the material type.
4. Apply steady, consistent pressure while allowing the variable pitch teeth to clear material efficiently.
5. For deep cuts through wood studs, use the full 1-5/8" cutting depth capability in single pass operation.
6. Clean saw teeth regularly during extended use and allow cooling periods to maintain optimal performance.
