Built to the HPHV series specification, it features a 3\/4 inch diameter, a 1-1\/2 inch length of cut, and a 0.015 inch corner radius that protects the cutting edge and reduces chipping on hard materials. The AlTiN PVD coating provides thermal resistance and surface hardness suited for dry and semi-dry machining. With four right-hand spiral flutes and a high helix angle, this tool is rated for both roughing and finishing operations. It is installed and operated by machinists and CNC programmers working in precision manufacturing.\u003c\/p\u003e\n\u003cp\u003eThis end mill is engineered for use on steel, stainless steel, cast iron, and hard materials, corresponding to ISO material groups P, M, K, and H. The Weldon flat shank and extended reach geometry make it appropriate for setups requiring additional clearance. It is compatible with EM-CV Form AD and EM IN-HSK Form A toolholding systems as specified by the manufacturer. Typical applications include contour milling, profiling, and slot work in aerospace, die and mold, and general machining environments where tool life and edge integrity are critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide submicron-grade construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating rated for steel, stainless steel, cast iron, and hard materials\u003c\/li\u003e\n  \u003cli\u003e0.015 inch corner radius reduces edge chipping and extends tool life in hard materials\u003c\/li\u003e\n  \u003cli\u003eFour right-hand spiral flutes with high helix angle for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank with extended reach for secure toolholder engagement\u003c\/li\u003e\n  \u003cli\u003eCenter cutting design allows plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eRated for both roughing and finishing in a single tool\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with EM-CV Form AD and EM IN-HSK Form A toolholding systems per manufacturer specification. Designed for machining steel, stainless steel, cast iron, and hard materials (ISO P, M, K, H groups). The 3\/4 inch Weldon flat shank is a standard interface for CNC machining centers and manual mills equipped with appropriate collet or shell mill holders.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and setup should be performed by a qualified machinist or CNC operator. Before changing tooling, ensure the machine spindle is fully stopped and the control is in a safe state. The Weldon flat must be properly aligned with the toolholder setscrew to prevent pullout under load. Verify runout with a dial indicator after clamping; excessive runout will shorten tool life and degrade surface finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: High\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Short\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Classification\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HPHV\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4067275\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51754831544626,"sku":"4067275","price":759.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cb4ea492584d08fc18dde8eb010d5d54_6bc3d010-4130-439d-ada3-72143b5f01d9.jpg?v=1788948988","url":"https:\/\/voomisupply.com\/products\/kennametal-4067275-corner-radius-end-mill-3-4-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
