Norton 662611-31539 Speed-grip Paper Disc A275 P400B 5 in

Product Description

The NORTON 662611-31539 is a 5-inch Speed-Grip paper disc designed for random orbital and disc sanders used in surface preparation and finishing applications. Built to the A275 specification and rated at P400B grit, this disc delivers fine finishing performance suited for sanding between coats, final smoothing, and light material removal on wood, metal, and painted surfaces. The hookless Speed-Grip attachment system allows fast, tool-free disc changes at the sander pad. Each order contains 100 discs, making this a bulk supply option well suited to production environments and high-volume finishing shops.

This disc is used in residential finishing, cabinet shops, automotive body prep, and light industrial surface work wherever a fine-grit abrasive is needed. The No Hole backing configuration is compatible with solid sander backing pads. P400B grit places this disc in the ultra-fine finishing range, appropriate for final passes before topcoat or clear application. Trade painters, finish carpenters, auto body technicians, and production sanders are the primary installers and users of this disc type.

Key Features

• 5-inch diameter with No Hole backing for use with solid sander pads

Compatibility

Installation Notes

Power down and unplug the sander before changing discs. Press the disc firmly and evenly onto the Speed-Grip backing pad to ensure full contact across the abrasive surface. Inspect the backing pad for wear or contamination before each disc change, as a damaged pad reduces disc adhesion and cutting performance. Abrasive disc selection and use should follow applicable workplace safety standards and the sander manufacturer guidelines.
