Built on a vitrified bond with an aluminum oxide abrasive, this wheel measures 7 inches in diameter and 3\/4 inches thick with a 1-1\/4 inches arbor hole. The 46-grit coarse grade removes material aggressively while the H hardness code and soft hardness rating help the wheel break down predictably to expose fresh abrasive. The 32A46-HVBE specification identifies the exact wheel formulation. Maximum operating speed is 3,600 RPM. Weighing 2.28 pounds, it is sized for bench-mounted or pedestal surface grinders used by machinists and tool-and-die professionals.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for surface and cylindrical grinding applications in production and maintenance environments. Its aluminum oxide abrasive is appropriate for grinding 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The one-side recessed profile — with a 2-3\/4 inches recess diameter and 1\/4 inches recess depth — provides clearance for flanges and reduces overall wheel weight. It is a practical choice for machine shops requiring a coarse-stock-removal wheel in a standard 7-inch diameter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive for use on steels, tool steels, stainless, aluminum, and cast iron\u003c\/li\u003e\n\u003cli\u003eVitrified bond for rigidity and consistent cutting action\u003c\/li\u003e\n\u003cli\u003e46-grit coarse grade delivers aggressive material removal\u003c\/li\u003e\n\u003cli\u003eH hardness code (soft rating) promotes self-dressing and reduces glazing\u003c\/li\u003e\n\u003cli\u003eType 5 one-side recessed profile with 2-3\/4 inches recess diameter and 1\/4 inches recess depth\u003c\/li\u003e\n\u003cli\u003eRated to 3,600 RPM maximum operating speed\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with surface grinders and cylindrical grinders accepting a 7 inches diameter, 1-1\/4 inches arbor hole Type 5 wheel.

Before mounting, ring-test the wheel for cracks and confirm the machine spindle speed does not exceed the wheel's 3,600 RPM maximum rating. Power down and lock out the grinder before changing wheels. Never force a wheel onto a flange — the arbor hole must fit freely without binding.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Hole Size\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Diameter\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Depth\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 46\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Rating\u003c\/strong\u003e: Soft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3,600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 32A46-HVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Gray\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.28 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NORTON\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66252942209\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541567308082,"sku":"66252942209","price":114.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/83c1343847e1ff20a4d12c2c84a13b13.jpg?v=1785879332","url":"https:\/\/voomisupply.com\/products\/norton-66252942209-surface-grinding-wheel-46-grit-7-in","provider":"Voomi Supply","version":"1.0","type":"link"}
