Norton 66252838193 Type 2 Grinding Wheel 6 in 120 Grit

Product Description

The NORTON 66252838193 is a Type 2 vitrified silicon carbide grinding wheel designed for precision tool grinding and sharpening applications. The wheel measures 6 inches in diameter with a 1-inch face width and fits a 1-1/4-inch arbor hole. At 120 grit with an I hardness code, it falls in the fine grade range, making it well suited for finishing passes and light material removal on hard, brittle materials such as carbide tooling, ceramics, and cast iron. It is rated to a maximum of 3,600 RPM and carries the internal specification designation 39C120-IVK.

This wheel is used in bench grinder and pedestal grinder setups commonly found in machine shops, tool rooms, and maintenance facilities. It is the appropriate choice when reconditioning carbide-tipped tools, sharpening masonry drill bits, or finishing hard non-ferrous materials. The green silicon carbide bond and fine grit make it a standard selection for toolroom technicians and machinists who need controlled stock removal with a clean surface finish. It is not intended for use on steel or ferrous metals.
