Norton 662529-39207 Type 27 Grinding Wheel 7 in Metal

Product Description

The NORTON 662529-39207 is a Type 27 depressed center grinding wheel engineered for metal grinding and stock removal in demanding fabrication and maintenance applications. Built with a Gemini Aluminum Oxide abrasive grain, this wheel delivers consistent cut rate and extended service life on ferrous metals. At 7 inches in diameter with a 1/8-inch thickness and a 7/8-inch arbor bore, it fits standard 7-inch angle grinders and is rated to a maximum of 8600 RPM. Licensed tradespeople and fabricators rely on this wheel for weld grinding, surface prep, and edge work where controlled material removal is required.

This grinding wheel is suited for use on mild steel, structural steel, and other ferrous metals in residential, commercial, and industrial settings. Typical applications include weld bead removal, surface blending, and deburring on flat or slightly contoured workpieces. The depressed center profile allows the disc to sit at a low angle to the workpiece, enabling flush and controlled grinding passes. It is commonly used by ironworkers, pipefitters, millwrights, and general fabricators working with angle grinders in shop or field conditions.
