Built from white aluminum oxide abrasive with a vitrified bond, this wheel delivers consistent, controlled cutting action across a fine 120-grit surface. The semi-friable grain structure allows dulled abrasive particles to fracture and expose fresh cutting edges, maintaining a sharp wheel face over extended use. At 7 inches in diameter and 1\/4 inch thick with a 1-1\/4 inch arbor hole, it fits standard surface grinder spindles and is rated to a maximum of 3600 RPM. Licensed grinding technicians and machinist-level trades install and dress this wheel as part of precision surface finishing operations.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for surface grinding applications on soft carbon steels, tool steels, and super alloys. It is designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. The fine grit and medium hardness rating make it well matched to finish-pass operations where tight tolerances and smooth surface finishes are required. The non-porous, non-tapered, no-recess Type 1 flat wheel profile supports flat and horizontal spindle surface grinder setups common in tool rooms and production grinding environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWhite aluminum oxide abrasive for consistent performance on tool steels and super alloys\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigid wheel structure and resistance to heat and coolant\u003c\/li\u003e\n\u003cli\u003eSemi-friable grain continuously self-sharpens to maintain cutting efficiency\u003c\/li\u003e\n\u003cli\u003e120 grit fine grade suited for finish grinding and tight tolerance work\u003c\/li\u003e\n\u003cli\u003eNon-porous, no-recess Type 1 flat wheel profile fits standard surface grinder arbors\u003c\/li\u003e\n\u003cli\u003eRated to 3600 RPM maximum operating speed\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 as stated by the manufacturer.

Always power down and lock out the machine before mounting or removing the wheel. Inspect the wheel for cracks or chips using the ring test before mounting, and never exceed the maximum rated RPM of 3600. Use proper flanges and blotters as required by the machine manufacturer and applicable safety codes.\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 Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 38A Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecifications Code\u003c\/strong\u003e: 38A120-KVBE\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: 0.25 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: 120\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Fine\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\u003eFriability\u003c\/strong\u003e: Semi-Friable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Non-Porous\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\u003eMaximum RPM\u003c\/strong\u003e: 3600\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: 0.79 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: 66252939834\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51539504038194,"sku":"66252939834","price":71.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bccd88f8ff91ef88cafbf754f4579e90.jpg?v=1785842013","url":"https:\/\/voomisupply.com\/products\/norton-66252939834-surface-grinding-wheel-120-grit-7in","provider":"Voomi Supply","version":"1.0","type":"link"}
