Norton 662611-38453 Zirconia Alumina Fiber Disc 60 Grit

Product Description

The NORTON 662611-38453 is a zirconia alumina fiber disc from the NorZon F826 product line, designed for aggressive material removal on metal, stainless steel, and other hard surfaces. At 4-1/2 inches in diameter with a 7/8-inch arbor hole and a 60-grit abrasive, this disc delivers a balance of cut rate and surface finish suited to weld blending, deburring, and surface conditioning tasks. It is sold in packs of 25 and installed on angle grinders or disc grinders used by fabricators, welders, pipefitters, and general metal tradespeople.

This fiber disc is intended for use in metal fabrication shops, structural steel work, and field welding applications where consistent stock removal is required. The 60-grit designation places it in the medium-coarse range, making it effective for removing mill scale, rust, and light surface defects before finishing operations. It fits standard 4-1/2-inch angle grinders commonly found on industrial and commercial job sites.
