Measuring 7 inches in diameter, 1\/2 inch thick, with a 1-1\/4 inch arbor hole, this wheel features 46-grit aluminum oxide abrasive bonded in a vitrified matrix at K hardness (medium). The 32AA46-KVTR specification designates a porous, open structure that promotes cool cutting and chip clearance. Rated to 3600 RPM, it delivers consistent coarse-grade material removal on hard carbon steels, soft carbon steels, and tool steels. Machinists and tool grinders install this wheel in production and maintenance environments where flat surface accuracy is critical.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for surface grinding applications on ferrous workpieces in both production shops and tool rooms. Compatible with surface grinders, cylindrical grinders, and CNC cutting tool machines, it handles a wide range of carbon and tool steel grades. The coarse 46-grit and porous 32A structure make it particularly effective for rapid stock removal passes where surface finish is a secondary priority to material removal rate.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e46-grit aluminum oxide abrasive for aggressive coarse-grade stock removal\u003c\/li\u003e\n\u003cli\u003eVitrified bond (32AA46-KVTR) provides a rigid, porous structure that resists heat buildup\u003c\/li\u003e\n\u003cli\u003eK hardness (medium) balances wheel wear rate against workpiece aggression on steel\u003c\/li\u003e\n\u003cli\u003eRated at 3600 RPM maximum operating speed\u003c\/li\u003e\n\u003cli\u003ePorous, no-recess Type 1 flat wheel geometry for standard surface and cylindrical grinder spindles\u003c\/li\u003e\n\u003cli\u003eSuitable for hard carbon steels, soft carbon steels, and tool steels\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with surface grinders, cylindrical grinders, and CNC cutting tool machines requiring a Type 1 flat wheel with a 1-1\/4 inch arbor bore.

Before mounting, inspect the wheel for cracks using a ring test and confirm the machine spindle speed does not exceed the 3600 RPM maximum rating. Always install proper wheel flanges and a blotter between the flange and wheel face. Dress the wheel with an appropriate diamond dresser before initial use to true the face and expose fresh abrasive.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 32A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 32AA46-KVTR\u003c\/li\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: 0.5 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\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\u003eHardness Rating\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStructure\u003c\/strong\u003e: Porous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Blue\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapered\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Hard Carbon Steels, Soft Carbon Steels, Tool Steels\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: CNC Cutting Tool Machine, Cylindrical Grinder, Surface Grinder\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: 66252938879\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538384093490,"sku":"66252938879","price":106.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7b6413e51c617adc1fe862e5f93350e8.jpg?v=1785823993","url":"https:\/\/voomisupply.com\/products\/norton-66252938879-surface-grinding-wheel-46-grit-7-in","provider":"Voomi Supply","version":"1.0","type":"link"}
