Norton 66261136712 Psa Disc 20 in 60 Grit Aluminum Oxide

Product Description

The NORTON 66261136712 is a pressure-sensitive adhesive (PSA) abrasive disc designed for aggressive material removal on large-surface grinding and finishing applications. Built on an X-weight cloth backing, this disc delivers the rigidity and durability required for demanding stock removal tasks. The abrasive grain is aluminum oxide, a reliable all-purpose mineral suited for ferrous metals, wood, and composites. At 60 grit, the disc falls in the medium-grade range, making it effective for blending, leveling, and intermediate surface preparation. The PSA mount allows fast, clean disc changes on compatible backup pads without additional hardware.

This disc is sized at 20 inches in diameter, making it appropriate for large floor grinders, wide-belt finishing machines, and industrial disc sanders used in woodworking shops, metal fabrication facilities, and flooring operations. The flexible cloth construction conforms moderately to surface contours while maintaining consistent abrasive contact. The brown X-weight backing resists tearing under load, extending disc life in high-pressure applications. No vacuum holes are included, so this disc is intended for solid-platen or non-vacuum backup pad setups.

Key Features

• 20-inch diameter PSA disc for large-format grinding and finishing equipment
• 60 grit aluminum oxide abrasive for medium-grade stock removal and surface blending
• X-weight cloth backing provides durability and resistance to tearing under load
• Flexible construction allows moderate conformability to workpiece surfaces
• Pressure-sensitive adhesive mount enables fast disc changes without fasteners
• No vacuum holes — designed for solid-platen or standard backup pad use

Compatibility

Designed for use with 20-inch PSA backup pads on large-format industrial disc sanders, floor grinders, and wide-surface finishing machines that accept PSA-mount abrasive discs without vacuum hole patterns.

Installation Notes

Installation is performed by trade professionals or machine operators familiar with large-format abrasive equipment. Power down and fully de-energize the machine before removing a spent disc or mounting a new one. Ensure the backup pad surface is clean and free of adhesive residue before applying the PSA disc to achieve full, even adhesion. Follow equipment manufacturer guidelines and applicable workplace safety standards when operating large grinding equipment.
