It features a 0.5-inch mill diameter, a 1.25-inch length of cut, and a 0.015-inch corner radius that reduces edge chipping and extends tool life in interrupted cuts. The four-flute, right-hand spiral geometry supports both roughing and finishing operations in a single tool. An AlTiN PVD coating provides thermal resistance and oxidation protection, making this end mill well suited to high-temperature cutting conditions. Licensed machinists and CNC operators working in job shops, tool rooms, and production environments are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis end mill is built for milling steel, stainless steel, cast iron, superalloys, titanium, and hard materials. Its 3.25-inch overall length and 0.5-inch Weldon flat shank provide secure tool holding in standard ER collet chucks and Weldon-style holders. The centercutting design allows plunge entry, and the normal-pitch flute spacing is suited to general-purpose material removal. It is a single-end tool from the H1TE series and carries a submicron carbide grade substrate for edge stability in tough alloys.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide submicron grade substrate for edge toughness in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating for thermal resistance during high-speed and dry cutting\u003c\/li\u003e\n\u003cli\u003e0.015-inch corner radius reduces stress concentration and extends edge life\u003c\/li\u003e\n\u003cli\u003eCentercutting design enables direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank provides positive anti-pullout engagement in tool holders\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand spiral, four-flute geometry for chip evacuation and surface finish\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with EM-CV Form AD and EM IN-HSK Form A tooling systems as specified by the manufacturer.

Ensure the spindle is fully stopped and the machine is in an energy-isolated state before inserting or removing the tool. Seat the Weldon flat fully against the set screw in the holder and torque the set screw according to the tool holder manufacturer specification. Verify runout with a dial indicator before beginning a production cut, particularly when machining superalloys or hardened materials where edge loading is critical.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 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\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 36 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Submicron Grade)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (PVD)\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\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\u003eSingle or Double End\u003c\/strong\u003e: Single\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 Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys, Titanium, Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: H1TE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.24 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: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6676502\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51742743560498,"sku":"6676502","price":285.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0c22a6c5a67254e355430d4bf48b183a_640d3fe7-f2c4-4e70-b012-868891626b0b.jpg?v=1788839225","url":"https:\/\/voomisupply.com\/products\/kennametal-6676502-corner-radius-end-mill-0-5in-4-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
