Built with aluminum oxide abrasive on a cloth backing with an X-weight backing grade, this disc delivers consistent cut and durability under heavy use. It operates at a maximum of 20000 RPM and measures 3 inches in diameter, making it a compact option for angle grinders and rotary tools equipped with a TR or Type R quick-change attachment system. The 180 grit rating places it in the very fine grade range, suited for surface prep, light deburring, and finish work. Licensed trade professionals and industrial technicians are the typical installers and users.\u003c\/p\u003e\n\u003cp\u003eThis disc is used in metal fabrication, maintenance, and surface conditioning applications where a fast disc swap is required.
