Norton 66260311783 Quick-change Disc 3in 60 Grit Diamond

Product Description

The NORTON 66260311783 is a quick-change coated abrasive disc designed for aggressive material removal on metals, coatings, fiberglass, and composites. Built around a diamond abrasive pattern on a flexible cloth backing, this 3-inch disc operates at up to 20,000 RPM with a coarse 60-grit cut. The Speed-Lok TR (Type III) attachment system allows fast, tool-free disc changes on compatible handheld disc sanders. Licensed tradespeople and fabricators working with fiberglass, composites, and tool steels will find this disc suited for cutting, rust removal, scale removal, and producing metallurgical stamps and coupons.

This disc fits residential and light industrial applications where a portable handheld disc sander is the primary tool. The flexible cloth backing conforms to irregular surfaces, making it practical for bodywork, composite repair, and metal prep in fabrication or maintenance environments. The 3-inch diameter is a common quick-change size for angle grinder attachments and dedicated disc sanders equipped with a Type R or TR interface. Its green color coding matches the D7210 series for easy identification on the job site.
