Instructions for using the BRUNNWEST Sheet Metal Hole Cutter
1. Loosen the scale nut on the cutter and adjust it to your desired hole size
2. Tighten the nut securely
3. Attach the cutter to your drill, then drill a small starter hole right at the center
of where you want the full hole. This guides the cutter accurately
4. Insert the cutter's pivot into the starter hole. Pierce the material to start the cut,
then rotate the cutter smoothly clockwise with a slight tilt opposite the cutting direction
Important: Guide the cutter during the turn without forcing the cut; let the bit do the work.
