Built on a vitrified bond with silicon carbide abrasive, this wheel measures 7 inches in diameter, 1\/4 inch thick, and carries a 1-1\/4 inch arbor hole. It is rated for a maximum of 3600 RPM and carries a medium grade, J hardness designation. The green-colored silicon carbide grain is well suited for hard, brittle, and non-ferrous materials. Machinists, tool-and-die workers, and metalworking tradespeople install this wheel on surface grinders and cylindrical grinders in production and maintenance environments.\u003c\/p\u003e\n\u003cp\u003eThis wheel is designed for use on 300 series stainless steel, titanium, aluminum, brass, bronze, copper, gray iron, masonry, and natural stone. It performs on CNC cutting tool machines, cylindrical grinders, and surface grinders. The vitrified bond provides rigidity and free-cutting action, making it a dependable choice in both shop floor and toolroom applications where consistent stock removal and surface finish control are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSilicon carbide abrasive grain — effective on non-ferrous metals, hard alloys, and masonry\u003c\/li\u003e\n  \u003cli\u003eVitrified bond construction for rigidity and free, cool cutting action\u003c\/li\u003e\n  \u003cli\u003e80 grit, medium grade (J hardness) for controlled stock removal\u003c\/li\u003e\n  \u003cli\u003eType 1 flat wheel profile with no recess — straight mounting on standard arbors\u003c\/li\u003e\n  \u003cli\u003e3600 RPM maximum speed rating\u003c\/li\u003e\n  \u003cli\u003eNon-porous structure maintains wheel integrity under wet or dry grinding conditions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eSuitable for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.
