How to get the best results
- Place a small piece of painter’s tape over the drilling spot to prevent wandering and chip-out.
- Begin with a slow drill speed and light, steady pressure; avoid forcing the bit to minimize edge fracture.
- Keep the surface cool with a steady flow of water to wash away debris and reduce heat buildup.
- Drill with a backer board or waste material beneath the workpiece to prevent blowout on the backside.
