Norton 666233-05638 Hook Loop Paper Disc 320 Grit 5 Inch

Product Description

The NORTON 666233-05638 is a 5-inch hook and loop paper disc engineered for fine grit finishing and micro-finishing applications. Built on a C-weight latex and paper backing, this disc uses P-graded aluminum oxide abrasive to deliver a cool, consistent cut across a broad range of substrates. A water-based, non-loading stearate coating reduces clogging and extends disc life. The hook and loop attachment system allows fast disc swaps on random orbital sanders and right angle grinders. At 320 grit, it is well suited for detail sanding passes where surface quality and finish consistency are the priority.

This disc is designed for use in finishing and micro-finishing work on aluminum, fiberglass, wood, composites, and painted or primed surfaces. It is appropriate for both shop and field use wherever a random orbital sander or compatible right angle grinder is in service. The 320 grit rating makes it a go-to choice for final sanding stages before coating or inspection. Trades working with composite panels, painted bodywork, or wood finishing will find this disc suitable for controlled material removal without aggressive scratch patterns.

Key Features

• P-graded premium aluminum oxide abrasive for a quick, cool cut and consistent surface finish

• Maximum operating speed of 15000 RPM

Compatibility

Designed for use with random orbital sanders and right angle grinders equipped with a hook and loop pad accepting 5-inch discs.

Installation Notes

Inspect the backing pad for wear or debris before mounting the disc, as a damaged pad can cause uneven contact and premature disc failure. Ensure the tool is powered off and unplugged before changing discs. Do not exceed the rated maximum operating speed of 15000 RPM. Operate the disc flat against the workpiece surface to maintain consistent abrasive contact and avoid edge loading.
