Norton 66261123590 Psa Sanding Disc 6 in 36 Grit Zirconia

Product Description

The NORTON 66261123590 is a 6-inch pressure-sensitive adhesive (PSA) sanding disc designed for aggressive material removal on metal, wood, and composite surfaces. It features a zirconia alumina abrasive grain rated at 36 grit, placing it in the very coarse grade category. The E-weight paper backing provides flexibility while supporting firm contact across curved and flat work surfaces. This disc mounts directly to PSA-compatible backup pads without fasteners, making changeovers fast during production grinding and blending operations. It is suited for metal fabrication shops, woodworking facilities, and maintenance environments where high stock removal is the priority.

The 66261123590 is intended for use on stationary disc sanders and portable grinders equipped with a PSA backup pad. The flexible paper backing allows it to conform slightly to contoured surfaces, making it effective for weld blending, rust removal, and surface prep before coating or finishing. This disc is sold individually and is part of the NORTON H875 series, which targets high-material-removal applications. It is installed by metal fabricators, maintenance technicians, and production grinders working with angle grinders or bench disc sanders.

Installation Notes

Installation is performed by pressing the adhesive-backed disc firmly onto a clean, dry PSA backup pad, ensuring full surface contact to prevent lifting during use. Confirm the backup pad and machine spindle are rated for the disc diameter before mounting. Power down and disconnect the tool from its power source before changing discs. Discard discs that show tearing, excessive loading, or delamination of the backing.
