Norton 66261170185 Hook Loop Disc Medium 5 Inch

Product Description

The NORTON 66261170185 is a 5-inch hook and loop non-woven abrasive disc designed for surface conditioning, blending, and finishing work across metal, wood, and composite materials. Built with an aluminum oxide abrasive bonded to a flexible nylon backing, this disc delivers consistent cut and surface contact on curved and irregular profiles. The medium grade abrasive suits stock removal tasks and intermediate finishing steps where a balance of cut rate and surface quality is needed. A maximum operating speed of 10,000 RPM makes it compatible with standard right-angle and random orbital disc grinders used in fabrication, maintenance, and surface prep applications.

This disc is suited for residential and commercial applications where surface conditioning or blending is required prior to coating, welding, or final finishing. The flexible nylon backing conforms to contours, making it a practical choice for work on pipe, tubing, weld beads, and formed sheet metal. It attaches via a hook and loop fastening system for fast disc changes without tools. The maroon color is standard for medium-grade non-woven discs in this product family. No vacuum holes are included, so it is intended for use without dust extraction ports.

Installation Notes

Installation is performed by pressing the disc firmly onto a 5-inch hook and loop backup pad until fully seated. Ensure the grinder or sander is powered off and disconnected from its power source before changing discs. Verify the tool spindle speed does not exceed the 10,000 RPM rating of this disc before operating. Inspect the backing pad for worn hooks that could allow disc slippage during use.
