Norton 66261019990 Hook Loop Disc 320 Grit 7 Inch

Product Description

The NORTON 66261019990 is a 7-inch hook and loop abrasive disc designed for surface preparation, blending, and finishing work. Built with a non-woven construction and aluminum oxide abrasive material, this disc delivers consistent scratch patterns at 320 grit — an extra fine grade suited for final finishing passes and light material removal. The flexible backing conforms to contoured surfaces, making it effective on irregular workpieces. It mounts via hook and loop attachment for fast disc changes without tools. At 0.12 pounds, the disc is lightweight and intended for single-use or limited-cycle applications in professional shop and field environments.

This disc is used in metal fabrication, woodworking, automotive bodywork, and general surface conditioning tasks where a controlled, fine scratch pattern is required. The extra fine 320 grit rating makes it appropriate for pre-finishing steps, intercoat scuffing, and surface cleaning on metal, painted surfaces, and composite materials. It is typically used with a right-angle grinder or random orbital tool equipped with a compatible hook and loop backing pad. No vacuum holes are present, so dust extraction requires an appropriate shroud or separate collection method.

Key Features

• 320 grit extra fine aluminum oxide abrasive for controlled finish work
• Non-woven construction provides flexible, conforming action on curved or irregular surfaces
• 7-inch diameter fits standard hook and loop backing pads

Compatibility

Designed as a replacement-style hook and loop abrasive disc for use with 7-inch hook and loop backing pads on right-angle grinders and random orbital sanders configured for that disc diameter.

Installation Notes

Installation is performed by pressing the hook side of the disc firmly onto a compatible hook and loop backing pad mounted to the grinder or sander. Ensure the backing pad is rated for the tool RPM before use. Inspect the disc for tears or delamination before each use and replace if damaged. Power down and disconnect the tool from its power source before mounting or removing the disc.
