Description
Chem-Set 6 in Radius Edge Hook and Loop Backup Pad is a radius edge backup pad that mounts 6 inch hook and loop abrasive discs on random orbital and dual action sanders. The rounded edge lets the pad flex over contours and shaped work without the rim digging in and leaving a witness mark.
Where the Radius Edge Backup Pad Is Used
Solid surface, countertop, and composite finishing crews use it when a flat, square edged pad would gouge a curved surface. The soft radius profile spreads pressure toward the edge of the disc and keeps the scratch pattern even on sinks, coves, and rounded panel returns. Typical work includes:
- Contour and edge sanding on solid surface and fiberglass parts.
- Feathering and blending on curved automotive and marine panels.
- Finish sanding where the disc must wrap slightly over an edge.
How the Radius Edge Backup Pad Fits Your Discs
The 6 inch face carries the hook and loop system, so discs press on and pull off cleanly for fast grit changes. Match the pad to 6 inch discs for full support across the abrasive. Keep the running speed within the sander rating, and replace the pad once the hook face stops gripping so discs do not spin loose during use.
