Norton 66261132734 Quick-change Disc 2in 120 Grit Ceramic Alumina

Product Description

The NORTON 66261132734 is a 2-inch quick-change abrasive disc from the Norton R983 series, designed for use with Speed-Lok TR (Type R) attachment systems on handheld disc sanders. Built with a premium ceramic alumina abrasive blend bonded to a polyester backing, this coated disc delivers fast, consistent stock removal on ferrous metals and stainless steel. The self-lubricating grain treatment extends disc life and helps maintain cut rate across the full service life of the disc. At a maximum operating speed of 30,000 RPM, it is rated for demanding grinding and finishing work where durability and speed matter.

This disc is suited for metal fabrication, welding prep, and surface finishing tasks in both shop and field environments. Typical applications include deburring, blending welds, and surface conditioning on 300 series stainless, 400 series stainless, cast iron, and soft carbon steels. The quick-change Type R attachment system allows rapid disc swaps without additional tooling, making it efficient for production or repetitive finishing operations on a handheld disc sander.

Installation Notes

Installation is performed by machinists, fabricators, or metal finishing technicians. Before mounting, confirm the tool spindle accepts the Type R quick-change button and that the tool's no-load RPM does not exceed the disc's 30,000 RPM maximum rating. Never exceed the rated maximum RPM, and inspect the disc for damage before each use. Discs should be stored flat, away from moisture and solvents, to preserve backing integrity.
