Built with ceramic abrasive grain in a vitrified bond, this wheel carries a 60 grit, medium grade designation with a G hardness code, placing it in the softer range of vitrified wheels for efficient, cool cutting. At 12 inches in diameter, 1 inch thick, and with a 3-inch arbor hole, it is sized for production surface grinders and cylindrical grinders. Rated at a maximum of 2070 RPM, it is installed by machinists and tool room technicians as part of precision grinding operations.\u003c\/p\u003e\u003cp\u003eThis wheel is formulated for grinding 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. Its semi-friable ceramic grain continuously self-sharpens under load, making it well suited for CNC cutting tool machines, cylindrical grinders, and surface grinders in both job shop and production environments. The porous, blue-colored wheel structure promotes coolant flow and chip clearance during aggressive passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic abrasive grain with vitrified bond for consistent, free-cutting action\u003c\/li\u003e\n\u003cli\u003e60 grit medium grade with G hardness code for aggressive material removal on hard metals\u003c\/li\u003e\n\u003cli\u003eSemi-friable grain structure continuously self-sharpens to reduce glazing\u003c\/li\u003e\n\u003cli\u003ePorous wheel construction promotes coolant flow and reduces heat buildup\u003c\/li\u003e\n\u003cli\u003eType 1 straight wheel profile with no recess, no taper\u003c\/li\u003e\n\u003cli\u003eRated for 400 series stainless, tool steels, titanium, super alloys, and irons\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.
