Norton 66261162324 Quick-change Disc 2 in 80 Grit Ceramic

Product Description

The NORTON 66261162324 is a 2-inch ceramic alumina quick-change abrasive disc designed for aggressive stock removal, weld blending, and deburring on metal surfaces. Part of the R980P series, it uses 100% ceramic grain that continuously fractures to expose sharper cutting edges throughout the disc life. The resin bond system maximizes grain retention, while a self-lubricating grain treatment reduces heat buildup during grinding. The polyester Y-weight backing provides a rigid platform suitable for demanding handheld disc sander applications. Rated to 30,000 RPM, this disc is built for fast, controlled material removal in professional fabrication and finishing workflows.

This disc is suited for use on 300 series and 400 series stainless steel in both fabrication shop and field service environments. It attaches via the Speed-Lok TR (Type III) quick-change system with a Type R attaching button, allowing fast disc swaps without tools. The 80-grit, medium-coarse grade makes it appropriate for initial weld blending passes, edge deburring, and surface preparation before finer finishing steps. It is intended for use with handheld disc sanders by metalworkers, pipefitters, fabricators, and maintenance technicians working on stainless steel assemblies.

Key Features

• 100% ceramic alumina grain continuously fractures to expose fresh, sharp cutting edges
• Resin bond system maximizes grain retention for longer disc life under heavy use
• Self-lubricating grain treatment reduces heat buildup and improves cut rate on stainless steel
• Rigid polyester Y-weight backing maintains consistent contact geometry on flat and near-flat surfaces
• Speed-Lok TR (Type III) quick-change mount with Type R attaching system for tool-free disc changes
• Rated to 30,000 RPM for use with standard handheld disc sanders

Compatibility

Compatible with handheld disc sanders equipped with a Speed-Lok TR (Type III) or Type R quick-change attachment system. Optimized for material removal on 300 series and 400 series stainless steel.

Installation Notes

Installation is performed by metalworkers and fabricators using standard handheld disc sanders. Verify the tool spindle accepts a TR or Type R quick-change mount before attaching the disc. Confirm the tool RPM rating meets or exceeds 30,000 RPM and that the disc is fully seated before operation. Wear appropriate PPE including eye protection and gloves when grinding or deburring metal surfaces.
