Norton 66252842179 Type 27 Grinding Wheel 3x1/4x3/8 18000 Rpm

Product Description

The NORTON 66252842179 is a Type 27 depressed center grinding wheel designed for metal grinding and cutting applications in fabrication and maintenance environments. Built with Gemini Aluminum Oxide abrasive, this wheel delivers consistent stock removal on ferrous metals. It measures 3 inches in diameter with a 1/4-inch thickness and a 3/8-inch arbor bore, and is rated for a maximum operating speed of 18000 RPM. Licensed tradespeople including ironworkers, pipefitters, welders, and general contractors rely on this wheel size for tight-access grinding work where a compact disc provides better control and reach than larger formats.

This wheel is suited for depressed center angle grinder use on metal surfaces in both residential construction and light industrial settings. The compact 3-inch diameter makes it well matched for weld dressing, deburring, and surface prep on pipe, structural steel, and sheet metal. It ships in a case quantity of 25 wheels, making it practical for shop stocking or job-site supply.
