Norton 66254461164 Flap Disc 80 Grit Type 29 4.5 Inches

Product Description

The NORTON 66254461164 is a Type 29 zirconia alumina flap disc designed for aggressive material removal and blending on metal surfaces. It features an 80 grit, medium-grade abrasive on a cloth backing, which provides durability and consistent cut throughout the life of the disc. The conical Type 29 geometry allows for better contact on flat and contoured surfaces, making it well suited for grinding, weld blending, and surface preparation work. Rated at 13,300 RPM, this disc is built for use on standard 4.5-inch angle grinders. It is installed and used by metal fabricators, pipefitters, ironworkers, and general industrial maintenance trades.

This flap disc is intended for grinding and surface conditioning on steel, stainless steel, and other ferrous metals in both fabrication shop and field environments. The 7/8 inch arbor hole fits the majority of 4.5-inch angle grinders in common use. The zirconia alumina abrasive delivers a self-sharpening cutting action that extends disc life compared to standard aluminum oxide discs. Typical applications include weld removal, edge deburring, and surface blending prior to coating or inspection. This is a single-disc package sold in a minimum order quantity of 10 units.
