Norton 66252942856 Type 6 Grinding Wheel 7 Inch 46 Grit

Product Description

The NORTON 66252942856 is a Type 6 straight-cup grinding wheel designed for tool grinding and surface grinding applications. Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent stock removal on ferrous metals and tool steels. It carries a 46 grit, J hardness (medium) rating and a maximum operating speed of 3,275 RPM. At 7 inches in diameter with a 0.5-inch face width and 1.25-inch arbor hole, it mounts to standard bench grinders and pedestal grinders used in machine shops, tool rooms, and maintenance facilities. The vitrified bond resists heat and holds its form under heavy grinding pressure.

This wheel suits bench or pedestal grinder setups in industrial, commercial, and trade-shop environments. It is used for sharpening high-speed steel tools, reshaping cutting edges, and general surface grinding tasks where a coarse, medium-hardness wheel is appropriate. The 46 grit provides fast material removal while the Type 6 cup profile allows face grinding contact. Machinists, tool-and-die workers, and maintenance technicians are the primary installers and operators of this wheel.
