Norton 66260311778 Quick-change Disc 60 Grit Diamond 2 in

Product Description

The NORTON 66260311778 is a 2-inch quick-change abrasive disc designed for use with Speed-Lok TR (Type III) attachment systems on handheld disc sanders. Built on a flexible cloth backing, it carries a diamond abrasive coating at 60 grit (coarse grade) and is rated to 30,000 RPM. The unique diamond abrasive pattern is engineered to increase disc life and lower cost per use while delivering an improved cut rate and finish quality. It is intended for installation and use by metalworking professionals, fabricators, and finishing technicians working with demanding materials.

This disc is suited for grinding and finishing applications on fiberglass, composites, tool steels, and similar hard materials. It is also effective for rust and scale removal and for producing metallurgical stamps and coupons. The 2-inch diameter makes it appropriate for tight, detail-oriented work with a handheld disc sander in both shop and field environments. The green disc color and black button are characteristic of the NORTON D7210 series.
