Merit Abrasives 66261138765 Quick-change Disc 24 Grit 7in

Product Description

The MERIT ABRASIVES 66261138765 is a 7-inch coated quick-change abrasive disc designed for aggressive material removal on metals and hard surfaces. Part of the Red Heat F981/F944 series, it features a premium ceramic alumina abrasive blend bonded to a heavyweight Y-weight fiber backing. The disc runs at a maximum of 8,600 RPM and attaches via a Type S quick-change system, making wheel swaps fast during production work. A self-lubricating grain treatment extends disc life and helps maintain cut rate as the disc wears. This disc is used by metal fabricators, welders, and maintenance technicians working with angle grinders and handheld disc sanders.

This disc is rated for use on 400 series stainless steel, cast iron, and soft carbon steels, making it well suited for weld grinding, surface prep, and stock removal in fabrication and maintenance settings. The 24-grit, very coarse cut removes material quickly and is the right choice when speed matters more than finish quality. The fiber backing provides rigidity and support under load, reducing flexing during flat or edge grinding. It is packaged individually and must be ordered in multiples of 25.
