Norton 662610-23947 Non-woven Disc Type 27 4.5 in Medium Grit

Product Description

The NORTON 662610-23947 is a Bear-Tex NEX Rapid Blend non-woven depressed center disc built for surface preparation, deburring, and blending on metal workpieces. Classified as a Type 27 disc with a 4.5-inch diameter, it uses a premium aluminum oxide grain bonded with a resin formula to deliver smooth, consistent material removal without smearing. The medium grit rating makes it effective at removing rust, coatings, and parting lines while keeping the workpiece surface free of unintended cuts or gouges. Weighing 0.015 pounds per disc, it is lightweight and designed for repeated use without significant degradation in performance or geometry.

This disc is suited for use on stainless steel, soft metals such as aluminum, and super alloys in fabrication, welding preparation, and finishing operations. It performs well in both production and job-shop environments where consistent surface condition is required between passes. Typical applications include weld blending, pre-paint surface prep, deburring cast and machined parts, and removing mill scale or oxidation from structural metal components. The uniform non-woven construction helps maintain part tolerance throughout the disc life cycle.

Installation Notes

This disc should be installed and operated by personnel familiar with angle grinder safety practices and applicable ANSI B11 or OSHA abrasive wheel standards. Verify the tool spindle speed rating meets or exceeds the maximum rated speed of the disc before mounting. Inspect the disc for damage before each use and discard any disc that shows tears, delamination, or distortion. Always use the appropriate guard for Type 27 discs on the grinder.
