What You Need
- Center Punch or Nail
- Dremel #212 Drill Press
1. Begin by making your hole area with a center punch or nail. The indentation will guide the accessory as you begin drilling.
2. At a low speed, use the #150 to drill through. To widen the hole, use the #9901 tungsten carbide cutter.
3. To avoid a ragged exit hole when drilling in sheet metal, clamp area between two panels of plywood before drilling.
