Norton 66261162330 Quick-change Disc 3 in 50 Grit Ceramic Tr

Product Description

The NORTON 66261162330 is a 3-inch quick-change abrasive disc in the R980P series, designed for aggressive material removal on stainless steel and other hard metals. It mounts via Speed-Lok TR (Type III) / Type R attachment and runs up to 20,000 RPM on handheld disc sanders. The ceramic alumina grain is 100% ceramic, which continuously fractures to expose sharp cutting edges throughout the disc's life. A resin bond system locks the grain firmly to the rigid polyester backing, and a self-lubricating grain treatment reduces heat buildup for a cooler, faster cut. At 50 grit coarse grade, this disc is built for rapid stock removal, weld blending, and deburring tasks.

This disc is rated for use on 300 series and 400 series stainless steel, making it a practical choice for fabrication shops, maintenance crews, and pipe trades that regularly work with stainless material. The 3-inch diameter fits compact handheld disc sanders used in tight-access weld zones and pipe joints. The orange cloth-backed construction is rigid and non-trimmable, suited for flat or near-flat surface work. Each package contains one disc, sold in minimum order multiples of 25, consistent with typical shop-consumable purchasing.

Key Features

• Resin bond system maximizes grain retention for extended disc life
• Self-lubricating grain treatment reduces heat at the cut zone
• 50 grit coarse grade delivers fastest stock removal, weld blending, and deburring rates
• Speed-Lok TR (Type III) / Type R quick-change attachment for tool-free disc swaps

Compatibility

Designed for use with handheld disc sanders equipped with a TR (Type III) or Type R Speed-Lok quick-change hub. Rated for material removal on 300 series and 400 series stainless steel.

Installation Notes

Mounting and disc changes should be performed with the sander powered off and unplugged. Verify the quick-change hub is fully seated and locked before operating. Do not exceed the maximum rated RPM of 20,000; confirm tool speed before use per ANSI B7.1 and applicable OSHA abrasive wheel standards. Inspect the disc for cracks or damage before each use and discard any disc that shows signs of delamination or backing separation.
