It measures 12 inches in diameter, 1 inch thick, with a 3-inch arbor hole, and weighs 9.045 pounds. The wheel uses an aluminum oxide abrasive bonded with a vitrified bond matrix, delivering consistent stock removal and a predictable wear pattern. Hardness code K and a medium grade classification place it in a mid-range wheel that balances wheel life against cut rate. Maximum operating speed is 2,070 RPM. The gray, non-tapered, porous wheel body promotes coolant flow and chip clearance during grinding passes. This wheel is intended for installation and use by qualified grinding machine operators and tool room professionals.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for surface grinding and cylindrical grinding applications across a broad range of materials. Rated material applications include 400 series stainless, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Compatible machine types include surface grinders, cylindrical grinders, and CNC cutting tool machines. It fits production tool rooms, maintenance shops, and machine shops where consistent flat or cylindrical stock removal is required on mixed material work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent, open cutting action\u003c\/li\u003e\n\u003cli\u003e60 grit, K hardness, medium grade — effective balance of cut rate and wheel life\u003c\/li\u003e\n\u003cli\u003ePorous wheel structure promotes coolant penetration and reduces heat buildup\u003c\/li\u003e\n\u003cli\u003eRated for 400 series stainless, carbon steels, tool steels, aluminum, and iron grades\u003c\/li\u003e\n\u003cli\u003eType 1 flat wheel profile with no recess — mounts directly to standard surface grinder spindles\u003c\/li\u003e\n\u003cli\u003eMaximum operating speed of 2,070 RPM\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 requiring a Type 1, 12-inch diameter wheel with a 3-inch arbor hole.
