Norton 66243522381 Surface Grinding Wheel 24 Grit

Product Description

The NORTON 66243522381 is a Type 1 straight surface grinding wheel designed for aggressive stock removal on ferrous and non-ferrous metals. Built with aluminum oxide abrasive and a resinoid bond, it measures 2-1/2 inches in diameter, 1/2 inch thick, with a 3/8 inch hole size. Rated at 24 grit with an R hardness code and very coarse grade, this wheel delivers fast, aggressive cutting action suited to rough grinding applications. It is rated for a maximum speed of 21,700 RPM. Licensed HVAC, plumbing, and mechanical trade technicians as well as industrial machinists performing surface preparation or weld cleanup will find this wheel a practical shop consumable.

This wheel is engineered for use with flexible shaft grinders and ID grinders. Its material compatibility spans a wide range of metals including 300 and 400 series stainless steel, hard and soft carbon steels, tool steels, titanium, super alloys, aluminum, brass, bronze, copper, cast iron, ductile iron, and gray iron. This range of material application makes it a versatile choice for maintenance shops, fabrication environments, and field service operations where varied workpiece materials are encountered.
