Tips

1. Make sure you are consistently drilling straight to avoid breaking bit and pick the drill in and out of the hole to avoid loading up the bit with chips.
2. It is recommended to use a center punch to position a starting point, preventing the drill bit from wobbling on the workpiece.
3. Every time smoke develops on a drilling operation (typically happen when drilling on hard timber), please stop and clear the swarf off the drill bit. You migh need to stop and clean it several times.
4. Best practice is to adjust all your settings (drill bit size, countersink size, depth stop location) and make a test drill into a piece of scrap before drilling the real workpiece
