Norton 666233-77541 Hook Loop Paper Disc 5 Inch 120 Grit

Product Description

The NORTON 666233-77541 is a 5-inch, 120-grit hook and loop abrasive disc designed for medium-grit sanding and finishing work on orbital sanders and right-angle grinders. Built on a C-weight latex-backed paper substrate, the disc stays flexible and conforms to contoured surfaces while resisting tears under sustained use. The abrasive layer uses P-graded premium aluminum oxide, which delivers a consistent, cool cut that reduces heat buildup and surface damage. A water-based, non-loading stearate coating minimizes clogging and extends disc life. Licensed tradespeople and skilled finishers working in body shops, fabrication shops, and finishing environments will find this disc reliable for production-level sanding tasks.

This disc is suited for finishing aluminum, fiberglass, composites, and painted or primed surfaces. The hook and loop backing allows fast mounting and removal on compatible random orbital sanders and right-angle grinders without adhesive or tools. It performs consistently across a broad range of substrates including wood, metals, and composite panels, making it a practical choice for both light fabrication and surface prep work where a smooth, uniform finish is required.

Compatibility

Designed for use with random orbital sanders and right-angle grinders that accept 5-inch hook and loop abrasive discs rated at 15000 RPM or lower.

Installation Notes

Confirm the tool's maximum RPM rating meets or exceeds the disc's 15000 RPM rating before mounting. Power down and disconnect or lock out the tool before attaching or removing the disc. Press the hook and loop backing firmly against the backing pad to ensure full surface contact before operation. Inspect the disc for tears or separation before each use and replace immediately if damage is found.
