Norton 662611-38592 Zirconia Alumina Fiber Disc 50 Grit

Product Description

The NORTON 662611-38592 is a zirconia alumina fiber disc engineered for aggressive material removal on metal, stainless steel, and weld surfaces. Built on the NorZon F826 abrasive platform, this disc delivers consistent cut rate and long service life under high-pressure grinding applications. At 7 inches in diameter with a 7/8 inch arbor hole, it fits standard right-angle grinders used daily in fabrication, maintenance, and industrial settings. The 50 grit specification positions it for heavy stock removal and weld blending where a coarser cut is required. Licensed tradespeople and fabricators in metalworking and industrial maintenance are the primary installers and users of this product.

This fiber disc is suited for use in metal fabrication shops, structural steel work, pipeline maintenance, and general industrial grinding applications. The zirconia alumina abrasive grain is well matched to ferrous metals, stainless steel, and high-alloy materials where consistent, fast stock removal is the priority. Packaged in quantities of 25, this disc is appropriate for shops and field crews that consume abrasives at production rates. It is compatible with right-angle grinders fitted with a 7/8 inch arbor or a compatible backing pad assembly.

Key Features

• Zirconia alumina grain (NorZon F826) for high cut rate and extended disc life
• 50 grit coarseness for heavy stock removal and weld blending
• 7 inch diameter fits standard right-angle grinders
• 7/8 inch arbor hole for secure mounting on compatible backing pads
• Sold in packs of 25 for production-volume use

Compatibility

Designed for use with right-angle grinders accepting a 7 inch fiber disc and 7/8 inch arbor backing pad. Confirm grinder speed rating meets or exceeds the maximum RPM marked on the disc before use.

Installation Notes

Fiber discs must be mounted on a matched rigid or semi-flexible backing pad rated for the disc diameter. Ensure the grinder is unplugged or its power source is isolated before mounting or removing the disc. Inspect the disc for cracks or damage before each use and never operate a damaged disc. Follow ANSI B11 and applicable shop safety standards for abrasive wheel use, including the use of appropriate face and eye protection.
