Part of the F826 Series, it carries a 36-grit very coarse grade with a resinoid bond and a fiber backing that holds up under sustained pressure and heat. The disc mounts via a threaded arbor hole with a 5\/8-11 center hole thread size and is rated for a maximum of 8,600 RPM. It is intended for use with the Norton AVOS Speed-Lok Back-Up Pad. Licensed tradespeople and experienced fabricators working with angle grinders are the primary installers and users.\u003c\/p\u003e\u003cp\u003eThis disc is suited for weld blending, rust removal, and surface prep on steel and other ferrous metals in both residential and light commercial fabrication environments. The zirconia alumina abrasive delivers a self-sharpening cut that maintains stock removal rates over the life of the disc, making it a practical choice for production grinding tasks where downtime between disc changes matters. The blue disc color helps with quick visual identification on the shop floor or in a service van.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7-inch disc diameter for broad surface coverage in a single pass\u003c\/li\u003e\n\u003cli\u003e36-grit very coarse grade for fast, aggressive stock removal\u003c\/li\u003e\n\u003cli\u003eZirconia alumina abrasive with resinoid bond for durability and consistent cut rate\u003c\/li\u003e\n\u003cli\u003e5\/8-11 threaded arbor hole attachment for secure, centered mounting\u003c\/li\u003e\n\u003cli\u003eRated to 8,600 RPM for compatibility with standard angle grinders\u003c\/li\u003e\n\u003cli\u003eCompatible with Norton AVOS Speed-Lok Back-Up Pad for quick disc changes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with the Norton AVOS Speed-Lok Back-Up Pad.
