Norton 662611-38637 Cloth Disc 2 in 36 Grit Extra Coarse

Product Description

The NORTON 662611-38637 is a zirconia alumina cloth abrasive disc in the R821 series, designed for aggressive material removal on metal, weld seams, and hard surfaces. At 36 grit extra coarse, it cuts fast and handles heavy stock removal where finer abrasives would load or wear prematurely. The closed-coat construction keeps abrasive grains packed tightly across the 2-inch disc face, maximizing cutting efficiency per pass. This disc attaches using the Turn On/Off (TS) system, which allows fast tool-free disc changes. Sold in packs of 25, it suits high-volume grinding operations in fabrication, maintenance, and metal prep environments.

This disc is suited for use in fabrication shops, maintenance and repair operations, and metal prep applications where rapid surface conditioning or weld removal is required. The TS attachment system is common on angle grinders and disc sanders configured for quick-change tooling. The 2-inch diameter fits compact grinder heads used in tight-access areas such as pipe welds, frame joints, and corner profiles. Installers in HVAC sheet metal work, plumbing rough-in, and electrical panel fabrication shops will find this disc appropriate for deburring and surface conditioning tasks.
