Measuring 8 inches in diameter and 3\/4 inches thick with a 1-1\/4 inch arbor hole, it uses 46-grit aluminum oxide abrasive bonded in a vitrified matrix. The coarse grade and I hardness code make it well-suited for aggressive cuts where rapid material removal matters. A one-side recess of 1\/4 inches deep and 3-1\/4 inches in diameter reduces wheel face contact and helps manage heat at the grind zone. Rated at a maximum of 3105 RPM, this wheel is designed for wet operation and is intended for installation by skilled grinding machine operators.\u003c\/p\u003e\n\u003cp\u003eThis wheel is used in surface grinding and cylindrical grinding applications across manufacturing, tool-and-die, and maintenance shops. Its aluminum oxide abrasive performs across a broad range of workpiece materials, including 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The porous, vitrified bond structure promotes coolant flow and chip clearance, which helps maintain a consistent cut over extended use. It carries the series designation 32A46-IVBE, which identifies the specific abrasive blend, grit, hardness, and bond combination used in the NORTON 32A product line.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 5 recessed wheel design with a 1\/4 inch deep, 3-1\/4 inch diameter one-side recess for reduced contact area and heat management\u003c\/li\u003e\n  \u003cli\u003e46-grit coarse aluminum oxide abrasive for fast stock removal on steel and iron workpieces\u003c\/li\u003e\n  \u003cli\u003eVitrified bond with porous structure supports coolant retention and chip clearance during wet grinding\u003c\/li\u003e\n  \u003cli\u003eI hardness code provides medium wheel hardness, balancing wheel life and cut aggressiveness\u003c\/li\u003e\n  \u003cli\u003eRated at 3105 RPM maximum for safe operation on compatible surface and cylindrical grinders\u003c\/li\u003e\n  \u003cli\u003eSeries specification 32A46-IVBE for precise cross-reference and replacement ordering\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with surface grinders and cylindrical grinders.
