3M 7100016627 Hook and Loop Disc 5 Inch P320 Grit

Product Description

The 3M 7100016627 is a coated abrasive disc designed for light sanding and finishing work on a wide range of surfaces. It uses an open-coat aluminum oxide abrasive that resists loading, keeping the disc cutting cleanly longer than closed-coat alternatives. The hook-and-loop backing attaches directly to random orbital sander pads for fast pad changes without tools. At a 5-inch diameter and P320 grit, this disc is suited for final surface prep, scuff sanding, and finish-stage work on metal, wood, primer, paint, fiberglass, and plastics. Maximum rated speed is 12,000 RPM.

This disc is used in automotive body, woodworking, and light fabrication settings where a refined surface finish is required before coating or topcoat application. Common applications include damp sanding on primers and e-coat in OEM and refinish environments. The open-coat construction is particularly effective where loading from soft primers or sealers is a concern. It is compatible with standard 5-inch hook-and-loop random orbital sander pads used in professional finishing shops and field service work.

Installation Notes

This disc is installed by a finishing technician or abrasives operator onto a 5-inch hook-and-loop sander pad. Confirm the sander is powered off and unplugged before attaching or removing the disc. Do not exceed the 12,000 RPM maximum rated speed. Inspect the hook-and-loop pad backing for wear or debris before attaching a new disc to ensure full contact and secure hold during operation.
