Norton 66261140502 Psa Disc 80 Grit Ceramic 5 Inches

Product Description

The NORTON 66261140502 is a pressure-sensitive adhesive (PSA) abrasive disc designed for aggressive material removal on a variety of surfaces. Part of the A975 series, this disc measures 5 inches in diameter, carries an 80-grit ceramic abrasive, and is backed by a B-weight paper backing for flexibility during use. Ceramic abrasive grain runs cooler and cuts faster than aluminum oxide, making it well-suited for high-production grinding and finishing tasks where consistent cut rate matters. Each package contains 100 discs.

This disc is intended for use on PSA-compatible random orbital and disc sanders commonly found in metal fabrication shops, automotive body work, and woodworking operations. The flexible paper backing conforms to slightly contoured surfaces, and the blue and white disc construction aids in visual identification on the shop floor. No vacuum holes are included, so this disc is suited for solid backing plates without dust-extraction ports.

Installation Notes

Installation is performed by trade professionals or experienced operators familiar with abrasive tooling. Before mounting, ensure the sander is fully powered off and unplugged. Clean the backing plate surface of any adhesive residue from the previous disc before applying the new disc to ensure full, even adhesion. Avoid running the disc beyond the RPM rating of the tool, and inspect each disc for tears or delamination before use.
