Norton 66261043391 Quick-change Disc 120 Grit 3 Inches

Product Description

The NORTON 66261043391 is a 3-inch ceramic alumina quick-change abrasive disc designed for aggressive material removal and surface finishing on metal. Part of the R980P series, it attaches via a Type S (Speed-Lok TS) hub system for fast, tool-free disc changes on handheld disc sanders. The 120-grit ceramic alumina grain self-sharpens during use, exposing fresh cutting edges throughout the disc life. A resin bond system locks grain in place to maximize retention and extend disc life. The polyester Y-weight backing provides durability under high-load grinding applications. This disc is rated to a maximum of 20,000 RPM.

This disc is engineered for use on 300 series and 400 series stainless steel, making it a direct choice for fabricators, maintenance welders, and metalworkers handling weld blending, deburring, and stock removal on stainless. The Speed-Lok TS Type S attachment system is compatible with handheld disc sanders that accept Type S quick-change hubs. The self-lubricating grain treatment reduces heat buildup at the workpiece surface, which is particularly important when working stainless steel where heat discoloration and metallurgical changes must be avoided. Sold individually, with a minimum order quantity of 25 units.

Installation Notes

Install and remove the disc by aligning the hub button with the sander arbor and pressing firmly until seated; no tools are required for disc changes on Type S systems. Always verify the tool spindle speed does not exceed the disc maximum RPM rating before use. Inspect the disc for damage before each use and do not use a disc that shows cuts, tears, or unusual wear. Wear appropriate PPE including eye protection and gloves when operating grinding equipment.
