Norton 662530-48983 Type 27 Grinding Wheel 9in Metal

Product Description

The NORTON 662530-48983 is a Type 27 depressed-center grinding wheel engineered for aggressive metal grinding and stock removal. Built with Gemini aluminum oxide abrasive, this wheel delivers consistent cut rate and long service life on ferrous metals and structural steel. At 9 inches in diameter with a 0.125-inch thickness and a 5/8-11 threaded arbor mount, it fits standard large-diameter angle grinders. The maximum rated speed is 6600 RPM. Metalworkers, fabricators, and welders reach for this wheel for heavy weld grinding, edge blending, and surface prep where material removal speed matters.

This grinding wheel is suited for use in metal fabrication shops, structural steel work, pipeline work, and general welding cleanup. The Type 27 depressed-center profile provides clearance for flat and contoured surface grinding. The 5/8-11 arbor thread is the standard for large angle grinders in the 9-inch class. Typical applications include weld bead removal, bevel grinding, and surface conditioning on carbon steel and similar ferrous materials.
