Norton 662611-38456 Resin Fiber Disc 36 Grit 4.5x7/8 in

Product Description

The NORTON 662611-38456 is a resin fiber disc built for aggressive material removal in demanding trade and industrial applications. Constructed with a zirconia alumina abrasive grain on an F826 Norzon fiber backing, this disc delivers a fast initial cut with consistent stock removal throughout its service life. The 36-grit designation makes it well-suited for heavy grinding, weld blending, and surface conditioning on metal substrates. It measures 4.5 inches in diameter with a 7/8-inch arbor hole, fitting standard right-angle grinders used by fabricators, pipefitters, and ironworkers.

This disc is designed for general-purpose grinding tasks across a range of trade applications including structural steel fabrication, weld preparation, pipeline work, and metal finishing. The coarse 36-grit cut rate makes it most effective on carbon steel, stainless steel, and other hard metals where rapid material removal is the priority. It is sold by the box with a minimum order quantity of one box.
