Norton 66261126556 Fiber Disc 24 Grit 5 Inches Zirconia

Product Description

The NORTON 66261126556 is a zirconia alumina coated fiber disc rated at 24 grit (Very Coarse) for aggressive material removal on metal and weld surfaces. Part of the F826P series, this 5-inch disc mounts via a 5/8-11 threaded arbor hole to a compatible back-up pad and spins safely up to 13,000 RPM. The resinoid bond holds the abrasive grain firmly under high-pressure grinding strokes. At 0.09 pounds, it is lightweight enough for extended overhead and vertical work without adding fatigue. Metal fabricators, pipe fitters, and weld-prep technicians reach for this disc when rapid stock removal and weld blending are the priority.

This disc is suited for use on ferrous metals, stainless steel, and structural weld joints in both shop and field environments. The F826P fiber backing withstands the heat and flex generated during heavy grinding passes. The blue disc color is consistent with the F826P series line for quick identification when multiple grit levels are in use. It is designed for use with the Norton AVOS Speed-Lok back-up pad system, making disc changes faster without removing the pad from the grinder.

Key Features

• 5/8-11 threaded arbor hole attachment mounts to standard threaded back-up pads
• 13,000 RPM maximum speed rating for use with standard angle grinders
• Resinoid bond maintains grain adhesion under sustained grinding pressure
• Fiber backing provides rigidity and heat resistance during heavy material removal passes
• Compatible with Norton AVOS Speed-Lok back-up pad for tool-free disc changes

Compatibility

Designed for use with the Norton AVOS Speed-Lok back-up pad system. Fits grinders and tools accepting a 5/8-11 threaded arbor back-up pad with a 5-inch disc capacity.

Installation Notes

Installation and disc changes should be performed with the grinder disconnected from power. Verify that the grinder's rated RPM meets or exceeds the disc's 13,000 RPM maximum before mounting. A metal fabricator or qualified operator should inspect the disc for cracks or damage before each use and discard any disc showing signs of delamination. Follow ANSI B7.1 and tool manufacturer guidelines for proper back-up pad and disc assembly.
