Norton 66261132736 Quick-change Disc 3in 36 Grit

Product Description

The NORTON 66261132736 is a coated quick-change abrasive disc engineered for aggressive material removal on metal surfaces. It mounts via a Speed-Lok TR (Type R) attachment system, making pad changes fast and tool-free on compatible handheld disc sanders. The disc measures 3 inches in diameter and carries a 36-grit ceramic alumina abrasive on a heavy-duty polyester (Y-weight) backing. The ceramic alumina grain blend is self-lubricating, which reduces heat buildup during extended grinding and extends disc life compared to conventional aluminum oxide abrasive. Rated to 20,000 RPM, this disc is well-suited for high-speed grinding applications in fabrication and maintenance environments.

This disc is designed for use on 300 and 400 Series stainless steel, cast iron, and soft carbon steels. It is intended for handheld disc sander applications where a Type R quick-change attachment is required. The extra coarse 36-grit grade makes it appropriate for weld blending, surface conditioning, and stock removal rather than finishing work. It is sold individually but requires a minimum order quantity of 25 units per order.

Installation Notes

Installation is performed by metalworkers and fabricators using a compatible Type R backup pad and handheld disc sander. Always confirm the tool's rated RPM meets or exceeds the disc's 20,000 RPM maximum before mounting. Inspect the disc for damage before each use and do not exceed the maximum RPM rating. Wear appropriate personal protective equipment including eye and face protection when operating abrasive discs.
