Tips for best results
- Align the pilot bit precisely at the center of the hole to prevent wandering—mark or punch a guide point first.
- Start drilling at a low speed to establish a clean entry, then ease up to the recommended pace for the material you’re cutting.
- Periodically stop to clear debris and reduce heat buildup, especially on denser stock.
- Ensure the workpiece is firmly secured to prevent shifting and produce a straighter hole.
- Inspect the carbide edge after heavy use and replace the cutter when you notice obvious wear to maintain cut quality.
