Built with an aluminum oxide abrasive and a vitrified bond, this wheel measures 7 inches in diameter, 1\/2 inch thick, and carries a 1-1\/4 inch arbor hole. The 46-grit, H-hardness (coarse grade) configuration delivers aggressive cutting action while the vitrified bond maintains shape retention and free-cutting performance under sustained load. The porous structure improves coolant flow and chip clearance. This wheel is rated to a maximum of 3,600 RPM and is suitable for use on surface grinders, cylindrical grinders, and CNC cutting tool machines.\u003c\/p\u003e\n\u003cp\u003eThis wheel is well-suited for surface grinding operations in job shop, tool room, and production environments. It is rated for use on 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The 32A series specification indicates a standard industrial-grade aluminum oxide formulation appropriate for general-purpose precision grinding where consistent finish and dimensional control are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 1 flat wheel profile with no recess — straight mounting on standard arbors\u003c\/li\u003e\n  \u003cli\u003e46 grit, H hardness, coarse grade for aggressive material removal\u003c\/li\u003e\n  \u003cli\u003eAluminum oxide abrasive with vitrified bond for shape retention and free cutting\u003c\/li\u003e\n  \u003cli\u003ePorous wheel structure promotes coolant penetration and chip evacuation\u003c\/li\u003e\n  \u003cli\u003eMaximum rated speed of 3,600 RPM\u003c\/li\u003e\n  \u003cli\u003eSpecification code 32A46-HVBE for direct cross-reference\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.
