Norton 66261132731 Quick-change Disc 2in 50 Grit Ceramic

Product Description

The NORTON 66261132731 is a quick-change coated abrasive disc from the Norton R983 series, designed for aggressive material removal on metal surfaces. It features a ceramic alumina abrasive blend bonded to a polyester cloth backing rated at Y-weight, providing high durability under demanding grind loads. The disc measures 2 inches in diameter and carries a 50 grit coarse rating, making it suited for fast stock removal rather than finish work. A self-lubricating grain treatment reduces heat buildup and extends disc life. The Speed-Lok TR Type R attachment system allows fast, tool-free disc changes on compatible handheld disc sanders. Licensed trades and fabricators working in production grinding applications will find this disc a reliable option for sustained cutting performance.

This disc is intended for use on 300 series stainless steel, 400 series stainless steel, cast iron, and soft carbon steels. It is engineered for handheld disc sander applications in industrial, fabrication, and maintenance environments. The 2-inch diameter is well suited to tight-access grinding work and weld dressing where a larger disc would be impractical. The coarse 50 grit cuts quickly through mill scale, rust, and light welds. This product is sold individually but carries a minimum order quantity of 25 units, reflecting its intended use in professional production or shop settings.

Installation Notes

Installation and disc changes should be performed by qualified personnel familiar with abrasive tool safety and applicable ANSI B7 standards. Always power down and disconnect the tool from its power source before mounting or removing a disc. Confirm the tool spindle speed does not exceed the 30,000 RPM disc rating before operation. Inspect the disc for damage or delamination prior to each use and do not use damaged discs.
