Norton 66261170186 Hook Loop Disc 7 Inches Medium

Product Description

The NORTON 66261170186 is a 7-inch non-woven hook and loop abrasive disc designed for surface conditioning, blending, and finishing work. It uses aluminum oxide abrasive bonded to a flexible nylon backing, which allows the disc to conform to contoured and flat surfaces alike. Rated at a maximum of 8500 RPM, it is suitable for use on angle grinders and random orbital sanders equipped with a hook and loop attachment pad. The medium grade abrasive makes it a practical choice for intermediate material removal and surface prep without aggressive stock removal.

This disc is commonly used in metalworking, fabrication, and maintenance applications where a consistent scratch pattern is needed before painting, coating, or welding. The maroon color designation indicates a medium-grade non-woven construction standard in the industry. The flexible nylon backing performs well on both flat stock and irregular profiles. It is suited for use by machinists, fabricators, maintenance technicians, and industrial tradespeople working on steel, aluminum, and other metals.

Installation Notes

Ensure the sander or grinder is powered off and unplugged before mounting or removing the disc. Confirm the tool spindle speed does not exceed the 8500 RPM disc rating before operation. Press the disc firmly onto the hook and loop pad to ensure full surface contact before use. Inspect the disc and backing pad for wear before each use and replace if the abrasive surface is glazed or the nylon backing is torn.
