Norton 66261136607 Psa Disc 10 in 50 Grit Aluminum Oxide

Product Description

The NORTON 66261136607 is a pressure-sensitive adhesive (PSA) abrasive disc designed for aggressive material removal on flat and contoured surfaces. Built on an X-weight cloth backing, this disc delivers the rigidity and durability needed for heavy stock removal applications. The coarse 50-grit aluminum oxide abrasive makes it well suited for grinding, shaping, and surface preparation on metal, wood, and composite substrates. At 10 inches in diameter, it mounts directly to PSA-compatible backup pads without fasteners or hook-and-loop hardware. This disc is part of the Norton R228 series and is flexible, allowing it to conform slightly to workpiece geometry without compromising cut rate.

This disc is used in industrial, fabrication, and production grinding environments where a high material removal rate is the priority. Typical applications include weld blending, deburring, and rough surface conditioning on flat platens or rotary sanders equipped with 10-inch PSA backup pads. The coarse grit and cloth backing make it a common choice for metalworking shops, millwork operations, and maintenance facilities handling heavy-duty prep work. No vacuum holes are included, so it is intended for solid-platen setups rather than dust-extraction sanding systems.

Compatibility

Designed for use with 10-inch PSA-compatible backup pads on rotary sanders and flat-platen grinding equipment. No specific compatible model numbers were provided in the product data.

Installation Notes

Installation is performed by trade professionals or experienced operators in fabrication and industrial settings. Before mounting, ensure the backup pad surface is clean and free of adhesive residue from previous discs, as contamination reduces bonding strength. Peel the release liner and apply the disc firmly to the center of the backup pad, pressing outward to eliminate air pockets. Always verify the equipment RPM rating does not exceed the disc and backup pad maximum speed ratings before operation.
