Constructed from aluminum oxide abrasive bonded with a vitrified matrix, it delivers consistent cutting action and free-cutting performance across a broad range of steel types. The wheel measures 7 inches in diameter, 1\/4 inch thick, with a 1-1\/4 inch arbor hole. At 80 grit with a K hardness code and medium grade rating, it is suited for moderate material removal where surface finish and dimensional control matter. Rated to 3600 RPM maximum, it is appropriate for standard surface grinder spindle speeds in production and tool-room environments.\u003c\/p\u003e\u003cp\u003eThis wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. Its aluminum oxide grain makes it a reliable choice for hard carbon steels, soft carbon steels, and tool steels. The porous, vitrified bond structure promotes coolant flow and chip clearance, reducing heat buildup during extended passes. It fits standard 1-1\/4 inch arbor spindles common in bench-top and floor-standing surface grinding equipment used in machine shops, maintenance facilities, and tool-and-die operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive grain for consistent performance on carbon and tool steels\u003c\/li\u003e\n\u003cli\u003eVitrified bond with porous structure promotes chip clearance and reduces heat\u003c\/li\u003e\n\u003cli\u003e80 grit, medium grade for balanced stock removal and surface finish\u003c\/li\u003e\n\u003cli\u003eK hardness code for moderate wheel hardness and controlled wear\u003c\/li\u003e\n\u003cli\u003eType 1 straight wheel profile with no recess, compatible with standard surface grinder mounting\u003c\/li\u003e\n\u003cli\u003eRated to 3600 RPM maximum for safe operation on production grinding equipment\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.
