Norton 66260307839 Psa Disc 5 in 60 Grit Diamond

Product Description

The NORTON 66260307839 is a 5-inch pressure-sensitive adhesive (PSA) abrasive disc designed for material removal on hard surfaces including stone, concrete, and composite materials. Built on a flexible cloth backing, this disc conforms to slightly irregular surfaces while maintaining consistent abrasive contact. The diamond abrasive grain at 60 grit delivers medium-coarse stock removal suited for grinding, smoothing, and surface prep tasks. The PSA mount means no fasteners or clamps — the adhesive backing bonds directly to a compatible PSA backup pad. This disc is used by flooring installers, tile setters, fabricators, and surface prep contractors.

This disc is suited for dry grinding and surface preparation applications where a flexible, conformable abrasive is needed on hard or semi-hard materials. The 5-inch diameter fits standard PSA backup pads of the same size. The D71S series construction uses a cloth backing that resists tearing under lateral load, making it appropriate for angle grinder and disc sander use in both shop and field environments. The green disc color is a series identifier and carries no performance meaning.

Key Features

• 5-inch diameter fits standard PSA backup pads
• Diamond abrasive grain for hard-material grinding and surface prep
• 60 grit medium-coarse cut for stock removal and smoothing

Compatibility

Designed for use with 5-inch PSA backup pads on disc sanders and angle grinders that accept PSA-mount abrasive discs.

Installation Notes

Installation is performed by pressing the adhesive side of the disc firmly onto a clean, dry 5-inch PSA backup pad. Ensure the backup pad surface is free of debris and old adhesive residue before mounting to achieve full adhesive contact. Power down and disconnect the tool from its power source before mounting or removing any abrasive disc. Discard discs that show tears, edge fraying, or loss of abrasive grain.
