Norton 66261136700 Psa Disc 16in 36 Grit Aluminum Oxide

Product Description

The NORTON 66261136700 is a pressure-sensitive adhesive (PSA) abrasive disc built for aggressive material removal on large surface grinders and floor machines. At 16 inches in diameter with a 36-grit aluminum oxide abrasive, this disc falls in the very coarse grade range, making it well-suited for rapid stock removal, paint stripping, and surface prep work where speed matters more than finish smoothness. The X-weight cloth backing provides the rigidity and tear resistance needed to handle high-pressure grinding applications without breaking down prematurely. No vacuum holes are included, keeping the mounting surface fully backed for maximum abrasive contact.

This disc is designed for use on stationary disc grinders, floor grinding equipment, and large-format sanding machines that accept 16-inch PSA-mount discs. It is a go-to choice for flooring contractors, metal fabricators, and industrial maintenance crews who need to remove coatings, level uneven substrates, or knock down weld seams and surface scale. The peel-and-stick PSA backing allows quick disc changes without hardware, reducing downtime between passes. It belongs to the NORTON R228 series.

Key Features

• 16-inch diameter fits large-format PSA disc grinders and floor machines
• 36 grit aluminum oxide for very coarse, high-rate material removal
• X-weight cloth backing resists tearing under high grinding pressure
• Pressure-sensitive adhesive mount for tool-free disc changes
• Flexible construction conforms to slightly irregular surfaces
• No vacuum holes — full-face abrasive contact across the entire disc

Compatibility

Designed as an OEM-style replacement or consumable for large-format disc grinders and floor grinding machines that accept 16-inch PSA-mount abrasive discs.

Installation Notes

Installation is performed by trade professionals including flooring contractors, metal fabricators, and industrial maintenance technicians. Before mounting, ensure the grinder platen is clean, dry, and free of old adhesive residue to achieve full PSA contact. Power down and disconnect the machine from its power source before changing discs. Inspect the backing pad for wear or damage prior to applying a new disc, as an uneven platen surface can cause premature disc failure.
