Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent cut rate and form retention under demanding machine cycles. The wheel measures 7 inches in diameter by 1\/2 inch thick with a 1-1\/4 inch arbor hole, runs at a maximum of 3600 RPM, and carries a 150-grit, Very Fine grade with an M (Medium) hardness rating. The semi-friable aluminum oxide grain is well suited to applications requiring controlled surface finish without excessive heat buildup. Grinding wheel technicians and tool room operators are the primary installers and dressers of this product.\u003c\/p\u003e\u003cp\u003eThis wheel is intended for surface grinding, cylindrical grinding, and CNC cutting tool machine operations. Noted material applications include soft carbon steels, tool steels, and super alloys. The Very Fine grit and Medium hardness combination targets finish passes rather than aggressive roughing, making it a strong fit for tool room and production environments where dimensional accuracy and surface finish are critical. It belongs to the NORTON 38A Type 1 series, specification 38A150-MV.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e150-grit aluminum oxide abrasive provides Very Fine material removal for finish-quality surface grinding\u003c\/li\u003e\n\u003cli\u003eVitrified bond maintains wheel form and allows efficient chip clearance during the grind cycle\u003c\/li\u003e\n\u003cli\u003eM (Medium) hardness rating balances wheel life against free cutting action on tool steels and super alloys\u003c\/li\u003e\n\u003cli\u003eSemi-friable grain structure supports self-sharpening behavior under moderate grinding pressure\u003c\/li\u003e\n\u003cli\u003eNon-porous, non-tapered, no-recess Type 1 straight wheel geometry fits standard surface and cylindrical grinder spindles\u003c\/li\u003e\n\u003cli\u003eWhite wheel color aids visual identification of aluminum oxide abrasive type on the shop floor\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.

Always power down and lock out the machine before mounting or removing a wheel. Inspect the wheel for cracks or chips using the ring test before installation, and never exceed the marked maximum RPM. Dress the wheel with an appropriate diamond or single-point dresser before the first cut to true the face and expose fresh abrasive.\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: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 150\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Very Fine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: M (Medium)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\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 Specification\u003c\/strong\u003e: 38A150-MV\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\u003eWheel Color\u003c\/strong\u003e: White\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: Soft Carbon Steels, Tool Steels, Super Alloys\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.14 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: 66252940595\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541569012018,"sku":"66252940595","price":156.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9a13bc7cd219117a30773e257daf46ba.jpg?v=1785879395","url":"https:\/\/voomisupply.com\/products\/norton-66252940595-surface-grinding-wheel-150-grit-7in","provider":"Voomi Supply","version":"1.0","type":"link"}
