It measures 7 inches in diameter, 1\/2 inch thick, with a 1-1\/4 inch arbor hole. The wheel is constructed from aluminum oxide abrasive in a vitrified bond, rated at a coarse 46 grit with an I hardness code (medium hardness rating). Rated to a maximum of 3600 RPM, this wheel is spec-coded 38A46-IVBE and is non-porous and non-tapered. It is a standard replacement-style grinding wheel installed by machinists and tool-and-die technicians on precision surface grinders and cylindrical grinders.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for surface grinding operations in job shops, tool rooms, and production machining environments. It performs on soft carbon steels, tool steels, and super alloys, making it a versatile choice for ferrous material applications. The semi-friable aluminum oxide grain self-sharpens during use, supporting consistent cut rates across long grinding sessions. Compatible with CNC cutting tool machines, cylindrical grinders, and surface grinders where a 7-inch Type 1 wheel is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 1 flat wheel profile — no recess, no taper, direct drop-in fit on standard arbors\u003c\/li\u003e\n\u003cli\u003e46 grit coarse aluminum oxide abrasive for aggressive stock removal\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigidity and cool cutting action on ferrous metals\u003c\/li\u003e\n\u003cli\u003eSemi-friable grain structure promotes self-sharpening for extended wheel life\u003c\/li\u003e\n\u003cli\u003eI hardness (medium) balances wheel life against cut rate on varied steel grades\u003c\/li\u003e\n\u003cli\u003e3600 RPM maximum rated speed for safe operation on compatible machines\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 accepting a 7-inch Type 1 wheel with a 1-1\/4 inch arbor hole.

Inspect the wheel for cracks or chips using a ring test before mounting. Never exceed the 3600 RPM maximum speed rating stamped on the wheel. Ensure the arbor hole and flanges are clean and properly sized before tightening to avoid wheel stress.\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: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Hole Size\u003c\/strong\u003e: 1-1\/4 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: I\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Rating\u003c\/strong\u003e: Medium\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\u003eWheel Type\u003c\/strong\u003e: Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 38A Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 38A46-IVBE\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: White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFriability\u003c\/strong\u003e: Semi-Friable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Non-Porous\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: Soft Carbon Steels, Tool Steels, Super Alloys\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.59 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: 66252941024\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542783852850,"sku":"66252941024","price":85.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/120a7bf6172c891ecdbea36b2effab3c.jpg?v=1785907357","url":"https:\/\/voomisupply.com\/products\/norton-66252941024-surface-grinding-wheel-46-grit-7in","provider":"Voomi Supply","version":"1.0","type":"link"}
