Norton 66261136583 5 Inch 120 Grit Sanding Disc

Product Description

The NORTON 66261136583 is a 5-inch diameter abrasive sanding disc built for medium-grade stock removal and surface finishing. Constructed with aluminum oxide abrasive bonded to an X-weighted cloth backing, this disc delivers consistent cut rate and durability under load. The maroon disc carries a 120 grit rating, placing it in the medium grade range suitable for blending, smoothing, and prep work on metal, wood, and composite surfaces. The flexible cloth construction conforms to contoured workpieces without sacrificing abrasive contact. No vacuum holes are included, making this disc suited for solid-pad backup configurations. Installed by machinists, fabricators, and finishing trades, this disc is a direct fit for 5-inch disc grinders and sanders.

This disc is designed for use in metalworking, woodworking, and general fabrication environments where a medium-grit finish is required. The X-weighted cloth backing supports aggressive sanding applications where paper-backed discs would degrade prematurely. Typical uses include weld seam blending, surface rust removal, and pre-paint surface preparation on flat and mildly contoured workpieces. The flexible construction allows the disc to maintain abrasive contact across irregular surfaces, reducing skip marks and uneven material removal. This product is sold individually and is well suited for benchtop disc sanders and handheld angle grinders with a 5-inch backup pad.

Key Features

• 5-inch diameter fits standard 5-inch disc grinders and backup pads
• 120 grit aluminum oxide abrasive for medium-grade material removal and surface blending
• X-weighted cloth backing provides durability and flexibility under load
• Flexible construction conforms to contoured and irregular surfaces
• No vacuum holes — designed for solid-face backup pad use
• Series R228 construction for consistent abrasive performance

Compatibility

Designed for use with 5-inch disc grinders, angle grinders, and benchtop sanders equipped with a solid 5-inch backup pad. No vacuum-hole pattern means this disc is not compatible with hook-and-loop or dust-extraction pad configurations requiring perforated discs.

Installation Notes

Installation is performed by machinists, metal fabricators, or finishing trade professionals. Before mounting, power down and disconnect the grinder or sander from its power source. Ensure the backup pad diameter matches the disc diameter exactly before securing. Inspect the disc for tears or delamination before each use — damaged abrasive discs should not be mounted.
