Norton 66261138816_O Fiber Disc 60 Grit 7 Inches

Product Description

The NORTON 66261138816_O is a 7-inch zirconia alumina fiber disc designed for aggressive material removal on metal, weld seams, and fabricated surfaces. Rated at a maximum of 8600 RPM and bonded with a resinoid bond, this disc delivers consistent cut rates across steel, stainless, and other hard metals. The fiber backing provides rigidity and support under load, making it suitable for use with standard right-angle grinders equipped with a backup pad and arbor hole attachment. At 60 grit, it falls in the medium grade range, balancing stock removal speed with surface finish control. It is part of the F826P series from Norton.

This disc is used in metal fabrication shops, welding operations, and maintenance environments where controlled grinding and blending are required. The zirconia alumina abrasive is a self-sharpening grain well suited to ferrous metals and demanding applications where consistent aggression is needed throughout the disc life. It is typically installed and operated by welders, fabricators, and maintenance technicians working with angle grinders on flat or contoured workpieces.

Key Features

• 7-inch disc diameter fits standard right-angle grinder setups with compatible backup pads
• Zirconia alumina abrasive grain for self-sharpening, long-lasting cut on ferrous metals
• 60 grit medium grade for balanced stock removal and surface control
• Resinoid bond holds abrasive grain firmly under high-load grinding conditions
• Fiber backing provides rigidity and support during aggressive grinding passes
• Maximum operating speed of 8600 RPM

Compatibility

Designed for use with right-angle grinders accepting a 7-inch fiber disc via arbor hole attachment and a compatible rigid or semi-flexible backup pad. Part of the Norton F826P fiber disc series.

Installation Notes

Fiber discs must be mounted on a compatible backup pad and arbor assembly rated for the disc diameter before use. Verify the grinder spindle speed does not exceed the 8600 RPM maximum rating marked on the disc. Inspect the disc for cracks or damage before each use and replace immediately if damage is found. Always wear appropriate personal protective equipment including eye protection and gloves when operating grinding equipment.
