Norton 66261136701 Psa Disc 80 Grit 16 Inch Aluminum Oxide

Product Description

The NORTON 66261136701 is a pressure-sensitive adhesive (PSA) abrasive disc designed for heavy-duty grinding and surface preparation on flat-plate and wide-belt finishing equipment. Built on an X-weight cloth backing, this disc delivers the rigidity and tear resistance required for aggressive stock removal. The abrasive media is aluminum oxide, a durable synthetic grain suited for ferrous metals, hardwoods, and composite materials. At 80 grit, it sits in the medium range, making it practical for initial surface leveling, weld blending, and scratch refinement before moving to finer grits. The PSA adhesive backing allows fast, tool-free mounting on compatible foam or rigid backup plates.

This disc is suited for industrial floor sanding, metal fabrication shops, woodworking operations, and maintenance facilities where large-diameter disc equipment is in regular use. The 16-inch diameter fits standard large-disc grinders and floor finishing machines that accept PSA-mount platens. The flexible cloth construction conforms slightly under load, helping maintain consistent contact across moderately uneven work surfaces. It is sold individually and is part of the NORTON R228 series.

Key Features

• PSA adhesive backing for fast, no-hardware disc changes on compatible platens
• X-weight cloth backing provides high tear resistance under aggressive grinding loads
• 80-grit aluminum oxide grain for medium-grade stock removal and surface leveling
• Flexible construction allows slight conforming contact on irregular surfaces
• No vacuum holes — suited for solid backup plates without dust extraction ports
• Part of the NORTON R228 series for consistent grit-to-grit performance matching

Compatibility

Designed for use with large-diameter flat-platen grinding and finishing machines that accept 16-inch PSA-mount abrasive discs with no vacuum holes.

Installation Notes

Power down and lock out the machine before removing the spent disc. Peel the PSA liner cleanly and align the disc to the platen edge before pressing firmly from center outward to eliminate air pockets. Ensure the backup platen surface is clean and free of adhesive residue from the previous disc, as contamination reduces bond strength and can cause the disc to release during operation. Disc replacement on large-format equipment is typically performed by maintenance technicians or abrasives-experienced shop personnel.
