Norton 66261136685 Psa Disc 40 Grit 16 Inches Aluminum Oxide

Product Description

The NORTON 66261136685 is a pressure-sensitive adhesive (PSA) abrasive disc designed for high-stock-removal grinding and surface preparation applications. Built on an X-weight cloth backing, the disc delivers the rigidity and durability needed for aggressive material removal on metal, wood, and composite surfaces. The 40-grit aluminum oxide abrasive provides a coarse cut that strips paint, levels welds, and removes rust or scale efficiently. The PSA mount allows fast disc changes on compatible back-up pads, reducing downtime during production or field work. Flexible construction conforms to slightly irregular surfaces without sacrificing cut rate.

This disc is suited for metal fabrication shops, woodworking operations, and surface preparation tasks where a large-diameter, high-aggression abrasive is required. At 16 inches in diameter, it is typically used on stationary disc sanders, floor grinding equipment, or large-format back-up pad assemblies. The coarse 40-grit specification makes it appropriate for initial stock removal passes before stepping to finer grits. It is not intended for finish sanding or polishing stages.

Key Features

• 40-grit aluminum oxide abrasive for aggressive, fast stock removal
• X-weight cloth backing provides stiffness and tear resistance under load
• Pressure-sensitive adhesive (PSA) mount for tool-free disc changes
• 16-inch diameter suits large stationary disc sanders and floor grinders
• Flexible construction allows light conformance to uneven surfaces
• Brown disc color; no vacuum holes, keeping the abrasive surface fully intact

Compatibility

Designed as an OEM-style replacement or standard supply disc for large-format PSA-compatible disc sanders and back-up pad assemblies accepting 16-inch PSA abrasive discs.

Installation Notes

Installation is performed by grinding and abrasives equipment operators or maintenance technicians. Before mounting, ensure the sander or grinder is powered off and unplugged or locked out per OSHA lockout/tagout procedures. Clean the back-up pad surface of debris and old adhesive residue before applying the new disc to ensure full PSA contact and prevent premature release. Do not exceed the maximum RPM rating of the back-up pad assembly.
