Norton 666233-77540 5 Inch 100 Grit Hook Loop Paper Disc

Product Description

The NORTON 666233-77540 is a 5-inch hook and loop paper sanding disc designed for medium-grit finishing work on a wide range of surfaces. Built on a C-weight high-latex paper backing, this disc stays flexible and conformable while resisting tears under load. The abrasive is P-graded premium aluminum oxide, which delivers a quick, cool cut and a consistent surface finish. A water-based, non-loading stearate coating minimizes clogging and extends disc life. The hook and loop attachment system makes mounting and swapping discs fast during production work. Rated at 15000 RPM, it is suited for use with random orbital sanders and right-angle grinders.

This disc is intended for finishing aluminum, fiberglass, composites, wood, and painted or primed surfaces in both production and finishing environments. It fits common 5-inch hook and loop backup pads used on random orbital sanders and right-angle grinders. The 100-grit designation places it in the medium range, making it well suited for surface preparation, scuff sanding, and final finishing passes before topcoat application. Professionals in body shop, composite fabrication, and general metalworking applications will find it a reliable choice for daily finishing tasks.

Installation Notes

Ensure the backup pad is clean and free of debris before attaching the disc to maintain full hook and loop engagement. Confirm the tool speed does not exceed 15000 RPM before operation.
