Norton 66261170183 Non-woven Hook Loop Disc 4.5 in Medium

Product Description

The NORTON 66261170183 is a non-woven hook and loop abrasive disc designed for surface conditioning, blending, and finishing applications. Built with aluminum oxide abrasive material bonded to a flexible nylon backing, this disc mounts via hook and loop attachment to compatible random orbital and angle grinders. The medium grade rating makes it well suited for general-purpose stock removal and surface prep on metal, wood, and composites. The flexible construction allows the disc to conform to contoured and irregular surfaces, reducing the chance of gouging or uneven material removal.

This disc is a common choice for metal fabrication shops, auto body technicians, woodworkers, and general maintenance trades needing consistent surface conditioning results. It is rated to a maximum speed of 12,000 RPM, covering the operating range of most standard 4.5-inch angle grinders and random orbital sanders. Typical applications include weld blending, rust removal, paint stripping, and pre-finish surface prep. The maroon color is consistent with medium-grade non-woven disc standards used across the industry. No vacuum holes are present, making it straightforward to install and swap out on the tool.

Installation Notes

This disc is installed by a grinding or finishing technician onto a compatible 4.5-inch hook and loop backing pad. Always confirm the tool's rated RPM does not exceed the disc maximum of 12,000 RPM before mounting. Power down and disconnect the tool from its power source before swapping discs. Inspect the backing pad hook surface for wear before attaching a new disc, as a worn pad can cause the disc to detach during operation.
