Norton 662611-38593 Resin Fiber Disc 36 Grit 7 in Zirconia

Product Description

The NORTON 662611-38593 is a resin fiber disc engineered for aggressive material removal in general purpose grinding and blending applications. Built with a zirconia alumina abrasive grain at 36 grit, this disc delivers a fast initial cut and maintains consistent stock removal throughout the disc life. Measuring 7 inches in diameter with a 7/8-inch arbor hole, it mounts directly to standard right-angle grinders. Resin fiber construction provides the rigid backbone needed to handle aggressive grinding pressure on metal and fabricated steel without premature breakdown.

This disc is suited for use in metal fabrication, welding prep, weld blending, and surface conditioning on ferrous metals. The 36-grit designation places it firmly in the coarse-cut range, making it the right choice when rapid material removal is the priority rather than fine finishing. It is sold by the box and is appropriate for use by metalworkers, fabricators, pipefitters, and maintenance technicians who need a dependable coarse disc for production or field work.

Installation Notes

Installation is performed by a metalworker or qualified technician. Before mounting, confirm the grinder is unplugged or the power source is locked out. Seat the disc firmly on a matched backing pad rated for the disc diameter and inspect for damage before operation. Always verify the grinder RPM rating meets or exceeds the disc RPM rating prior to use, and wear appropriate personal protective equipment including face shield and gloves.
