Norton 662528-43244 Type 27 Grinding Wheel 9x1/8 Metal

Product Description

The NORTON 662528-43244 is a Type 27 depressed center grinding wheel designed for aggressive material removal on metal surfaces. Built with a Zirconia Alumina abrasive grain — marketed under the Charger line — this wheel delivers consistent cut rates and long service life on ferrous metals and structural steel. It measures 9 inches in diameter by 1/8 inch thick and mounts on a 5/8-11 threaded arbor. Maximum operating speed is 6,600 RPM. The 1/8-inch profile makes it well suited for general-purpose grinding rather than cutting, providing enough face width for blending welds, removing slag, and grinding down surface irregularities.

This wheel is used in fabrication shops, construction sites, and maintenance applications where a right-angle grinder is the tool of choice. The 9-inch diameter and 5/8-11 arbor size position it for medium to large angle grinders. Typical applications include weld blending on structural steel, deburring heavy plate, and surface preparation before coating or inspection. It is sold individually, with a minimum order quantity of 10 units.

Installation Notes

Installation must be performed by a qualified operator familiar with angle grinder safety protocols. Always ensure the grinder is unplugged or the battery is removed before mounting or changing wheels.
