Norton 66261138607 Quick-change Disc 1 in 80 Grit Zirconia

Product Description

The NORTON 66261138607 is a 1-inch zirconia alumina quick-change abrasive disc designed for use with Speed-Lok TS (Type II) attachment systems on handheld disc sanders. Rated at 80 grit medium coarse, it delivers aggressive stock removal and is built on a rigid Y-weight polyester backing that resists moisture and stands up to repeated use. The semi-open coat construction reduces loading on the abrasive surface, extending disc life during demanding operations such as weld blending, deburring, and surface conditioning. Licensed tradespeople and fabricators working with metals and wood turn to this disc for consistent, fast cut rates.

This disc is suited for work on 300 and 400 series stainless steel, aluminum, brass, bronze, hard and soft carbon steels, and hard and soft woods. It is intended for use on handheld disc sanders equipped with a Type S or TS quick-change attachment interface. The 1-inch diameter makes it well-suited for tight areas, contoured surfaces, and detail grinding where a larger disc cannot reach. The R860 series designation places it in a line engineered specifically for high-contact metal fabrication and woodworking environments.

Installation Notes

Installation is performed by metalworkers, fabricators, and finishing trades using handheld disc sanders. Confirm the tool spindle uses a Type S or TS quick-change interface before mounting the disc. Do not exceed the 40000 RPM maximum speed rating. Inspect the disc for damage before each use and discard any disc showing cracks, tears, or delamination in the backing.
