Norton 662611-38591 Zirconia Alumina Fiber Disc 60 Grit

Product Description

The NORTON 662611-38591 is a zirconia alumina fiber disc engineered for aggressive material removal on metal, stainless steel, and other hard surfaces. Built on the NorZon F826 abrasive specification, this disc delivers a consistent cut rate and long service life under the heavy pressure common in grinding and blending applications. At 7 inches in diameter with a 7/8-inch arbor hole and a 60-grit rating, it balances stock removal speed with surface finish quality. Licensed tradespeople and fabricators handling structural steel, weld seams, and surface prep work rely on this grade for production-rate grinding tasks.

This fiber disc is suited for angle grinder use in both residential fabrication shops and commercial metalworking environments. The 60-grit cut is appropriate for weld removal, deburring, edge blending, and rust or scale removal on ferrous and non-ferrous metals. It is packaged in quantities of 25 discs per unit, making it practical for ongoing shop or field use where disc consumption is high. The 7-inch size fits standard large-diameter angle grinders commonly used in structural and sheet metal work.

Key Features

• Zirconia alumina abrasive grain (NorZon F826) for high cut rate and extended disc life
• 60-grit rating balances aggressive stock removal with acceptable surface finish
• 7-inch diameter with 7/8-inch arbor hole fits standard large angle grinders
• Fiber backing provides rigidity and resistance to tearing under grinding pressure
• Packaged 25 discs per unit to support production-volume grinding tasks

Compatibility

Designed for use with angle grinders accepting a 7-inch fiber disc with a 7/8-inch arbor hole. Suitable for grinding and blending applications on ferrous metals, stainless steel, and similar hard materials.

Installation Notes

Fiber discs must be mounted on a backing pad rated for the disc diameter and the grinder's maximum RPM before use. Verify the grinder's rated speed does not exceed the disc's maximum RPM rating before mounting. Always wear appropriate PPE including a face shield, gloves, and hearing protection when operating angle grinders. Inspect the disc for cracks or damage before each use and discard any disc that shows visible defects.
