1. Insert the mandrel securely into a compatible 3/32" e-file.
2. Fit a compatible sanding band firmly over the mandrel.
3. Select a sanding-band grit appropriate for the service.
4. Use light, controlled passes across small or detailed areas.
5. Stop the e-file before changing the sanding band.

Professional Tip: Match sanding-band grit to the service instead of using extra pressure.
