Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent cutting action and open wheel structure suited for surface, cylindrical, and CNC cutting tool machine applications. The wheel measures 8 inches in diameter, 0.5 inches thick, with a 1.25-inch arbor hole, and is rated for a maximum of 3,600 RPM. At medium grade with an I hardness code and 80 grit, it balances material removal rate with surface finish quality. Weighing approximately 2.09 pounds, it is installed by tool room machinists and grinding machine operators.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both production and tool room environments. It is rated for grinding 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The porous structure of the wheel helps clear chips and reduce heat buildup during extended grinding passes, making it a practical choice for shops working across a range of ferrous and non-ferrous workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent, open cutting action\u003c\/li\u003e\n  \u003cli\u003e80 grit medium grade construction balances stock removal and surface finish\u003c\/li\u003e\n  \u003cli\u003ePorous wheel structure promotes chip clearance and heat dissipation\u003c\/li\u003e\n  \u003cli\u003eRated to 3,600 RPM for use on standard surface and cylindrical grinding equipment\u003c\/li\u003e\n  \u003cli\u003eNo recess, no taper Type 1 straight wheel configuration\u003c\/li\u003e\n  \u003cli\u003eSeries specification 32A80-IVBE for direct cross-reference sourcing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.
