Built on the H1TE series platform, it features a 3\/4 inch diameter with a 0.03 inch corner radius and four helical flutes ground to a 36-degree helix angle. The AlTiN PVD coating provides heat and oxidation resistance for extended tool life at elevated cutting temperatures. At 4.5 inches overall length with a 1 inch length of cut, this single-end, centercutting tool handles both roughing and finishing passes. The Weldon flat shank and extended reach design make it well-suited for rigid, repeatable setups in CNC machining centers.\u003c\/p\u003e\n\u003cp\u003eThis end mill is engineered for use on steel, stainless steel, cast iron, superalloys, titanium, and hard materials, covering ISO material codes P, M, K, S, and H. The short flute geometry with a normal pitch and right-hand cutting and flute direction supports controlled chip evacuation in typical production milling scenarios. It is compatible with EM-CV Form AD and EM IN-HSK Form A toolholding systems as noted by the manufacturer. Machinists and CNC operators running multi-material production cells or job-shop environments will find this end mill well-suited to a broad range of workpiece materials without a dedicated tool change.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlTiN PVD coating for high-temperature performance on steel, stainless, and hard materials\u003c\/li\u003e\n  \u003cli\u003e0.03 inch corner radius reduces stress concentration and extends workpiece edge life\u003c\/li\u003e\n  \u003cli\u003eFour right-hand helical flutes at 36-degree helix for balanced roughing and finishing capability\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank with extended reach provides secure clamping and access to deeper features\u003c\/li\u003e\n  \u003cli\u003eSubmicron carbide grade supports tight tolerances and consistent tool life in high-hardness applications\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 documentation.

Ensure the machine spindle is fully stopped and the tool magazine is in a safe state before mounting or removing the end mill. Seat the Weldon flat fully in the holder and torque the set screw per the toolholder manufacturer's specification. Verify runout with a dial indicator before initiating the first cut, as excessive runout accelerates edge wear and can compromise dimensional accuracy.\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\u003eCorner Radius\u003c\/strong\u003e: 0.03 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch (1.3780 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 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\u003eNeck Diameter\u003c\/strong\u003e: 0.7050 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 36 degrees\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\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Normal\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\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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 Index\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\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Short\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: H1TE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys, Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.817 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: 6767864\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51747516350770,"sku":"6767864","price":1037.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d34faf266541cd5108e35dffd5989018_8f7142eb-b41f-4b5c-88f2-4d4328fc98e2.jpg?v=1788881725","url":"https:\/\/voomisupply.com\/products\/kennametal-6767864-corner-radius-end-mill-3-4in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
