Norton 66261136517 Psa Disc 2 in 100 Grit Aluminum Oxide

Product Description

The NORTON 66261136517 is a 2-inch pressure-sensitive adhesive (PSA) abrasive disc designed for precision surface finishing on metal, wood, and composite materials. Built on an X-weight cloth backing, this disc delivers the rigidity and durability needed for demanding grinding and finishing applications. The aluminum oxide abrasive cuts at 100 grit, placing it in the fine-grade range for controlled material removal and surface refinement. The PSA mount allows fast, tool-free disc changes on compatible rotary and orbital backing plates. This disc is used by metalworkers, fabricators, and finishing technicians who need consistent cut rates in production or repair environments.

The 66261136517 is suited for both shop and field use where a small-diameter, fine-grit disc is required. At 2 inches, it fits backing plates used on die grinders and small random-orbit sanders common in metal fabrication, automotive bodywork, and woodworking finishing operations. The flexible cloth construction allows the disc to conform slightly to curved or contoured surfaces without tearing. It is sold individually, with a minimum order quantity of 50 units, making it appropriate for production shops and service operations that cycle through abrasives regularly.

Key Features

• 100-grit aluminum oxide abrasive for fine-grade surface finishing and controlled material removal
• X-weight cloth backing provides durability and resistance to tearing under load
• Flexible construction allows conformance to contoured and curved workpiece surfaces
• PSA (pressure-sensitive adhesive) backing enables fast, tool-free disc mounting and changes
• No vacuum holes — compatible with standard solid backing plates
• Part of the Norton R228 series

Compatibility

Designed as an OEM-style replacement or production abrasive for use with standard 2-inch PSA backing plates on die grinders and small rotary or orbital finishing tools.

Installation Notes

Installation is performed by pressing the PSA disc firmly onto a clean, dry 2-inch backing plate, ensuring full surface contact to prevent edge lifting during use. Confirm the backing plate RPM rating meets or exceeds the tool speed before operation. Inspect the disc for damage before each use and replace immediately if tearing, delamination, or uneven wear is observed. No special tools are required for mounting, but the backing plate surface should be free of debris and residual adhesive from prior discs.
