Part of the F980 Series, it features a coarse 50-grit resinoid-bonded abrasive on a fiber backing for durability under high-pressure grinding. The threaded arbor hole accepts a 5\/8-11 center hole fitting and is designed for use with the Norton AVOS Speed-Lok Back-Up Pad. Rated to 8,600 RPM, this disc is suited for weld removal, surface prep, and heavy stock removal tasks performed by metalworkers, fabricators, and maintenance technicians.\u003c\/p\u003e\n\u003cp\u003eThis disc is intended for angle grinder applications where consistent cut rate and disc longevity are required. The ceramic alumina abrasive self-sharpens during use, maintaining cut efficiency longer than standard aluminum oxide on demanding materials. The orange fiber backing and resinoid bond provide structural integrity during aggressive grinding passes. Sold individually, with a minimum order quantity of 10 units, it is a practical choice for shop stock or field service kits.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7-inch disc diameter fits standard large angle grinders\u003c\/li\u003e\n  \u003cli\u003e50-grit coarse ceramic alumina abrasive for high material removal rates\u003c\/li\u003e\n  \u003cli\u003eThreaded arbor hole with 5\/8-11 thread for secure attachment to a threaded arbor\u003c\/li\u003e\n  \u003cli\u003e8,600 RPM maximum speed rating for safe high-speed operation\u003c\/li\u003e\n  \u003cli\u003eResinoid bond on fiber backing maintains disc integrity under load\u003c\/li\u003e\n  \u003cli\u003eDesigned for use with Norton AVOS Speed-Lok Back-Up Pad\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the Norton AVOS Speed-Lok Back-Up Pad via a 5\/8-11 threaded arbor hole attachment.
