Built with aluminum oxide abrasive and a vitrified bond, this wheel measures 7 inches in diameter and 3\/4 inches thick, with a 1-1\/4 inch bore. The 46-grit coarse grade and K hardness rating (medium wheel hardness) deliver aggressive cutting action while maintaining wheel integrity at speeds up to 3600 RPM. A one-side recess measuring 3 inches in diameter and 1\/4 inch deep reduces weight and allows clearance at the wheel flange. Licensed HVAC techs, machinists, and tool-and-die professionals working with surface or cylindrical grinders will recognize this as a workhorse wheel for high-material-removal passes.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for surface and cylindrical grinding operations across a broad range of materials including 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is compatible with both surface grinders and cylindrical grinders. The 32A Series designation identifies the specific aluminum oxide grain structure, which is optimized for consistent finish on harder ferrous alloys. At 2.86 pounds, it handles well on standard spindle setups without excessive vibration when properly dressed.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive with vitrified bond for rigid, consistent grain exposure\u003c\/li\u003e\n\u003cli\u003e46-grit coarse grade for high material removal rates on steel and iron\u003c\/li\u003e\n\u003cli\u003eK hardness code, medium-rated wheel hardness for balanced cut and wheel life\u003c\/li\u003e\n\u003cli\u003eType 5 one-side recessed profile, 3 inches recess diameter x 1\/4 inch deep, for flange clearance\u003c\/li\u003e\n\u003cli\u003eRated to 3600 RPM maximum operating speed\u003c\/li\u003e\n\u003cli\u003eSuited for 400 series stainless, carbon steels, tool steels, aluminum, and multiple iron grades\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with surface grinders and cylindrical grinders.

Power down and lock out the grinder completely before mounting or removing any wheel. Inspect the wheel for cracks or chips before each use — never mount a damaged wheel. Always use the appropriate flanges and blotters, and perform a ring test prior to mounting.\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\u003eBore (Hole Size)\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Diameter\u003c\/strong\u003e: 3 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\u003eRecess Type\u003c\/strong\u003e: One-Side\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: K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 32A Type 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecifications Code\u003c\/strong\u003e: 46K8V32A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Blue \/ Gray\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Non-Porous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.86 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\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: 66253246828\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542962471218,"sku":"66253246828","price":35.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6be0edcb83c59c1c2278051b2fc15de0.jpg?v=1785912348","url":"https:\/\/voomisupply.com\/products\/norton-66253246828-surface-grinding-wheel-7in-46-grit-type-5","provider":"Voomi Supply","version":"1.0","type":"link"}
