Built to H1TE series specifications, it features a 3\/8 inch diameter with a 0.015 inch corner radius that reduces stress concentrations at part edges and extends tool life. The AlTiN PVD coating provides high heat resistance, making it well-suited for dry and high-speed cutting environments. With 4 right-hand flutes and a 36-degree helix, this end mill delivers both roughing and finishing capability in a single tool. It is installed by machinists and CNC operators working on mills, machining centers, and manual knee mills.\u003c\/p\u003e\n\u003cp\u003eThis end mill is designed for cutting steel, stainless steel, cast iron, superalloys, titanium, and hard materials. The centercutting geometry allows for plunge entry, expanding its range of use in slotting, profiling, and pocket milling operations. The Weldon flat shank provides positive drive and reduces pullout risk in high-feed applications. Compatible tool holders include EM-CV Form AD and EM IN-HSK Form A style holders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.015 inch corner radius reduces edge chipping and stress risers on finished workpiece corners\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating delivers elevated heat and oxidation resistance for dry or high-speed cutting\u003c\/li\u003e\n  \u003cli\u003eSubmicron solid carbide substrate provides rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eCentercutting design permits direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank ensures secure, slip-resistant seating in compatible holders\u003c\/li\u003e\n  \u003cli\u003eSingle end, right-hand cut, normal pitch  -  suited for both roughing and finishing passes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with EM-CV Form AD and EM IN-HSK Form A tool holders.

Ensure the spindle is fully stopped and the machine is powered down before loading or removing the tool. Seat the Weldon flat shank fully into the holder and tighten the set screw against the flat to prevent pullout under load. Verify runout with a dial indicator before beginning the cut, as excessive runout will accelerate edge wear and compromise corner radius 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\/8 inches (0.3750 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\u003eLength of Cut\u003c\/strong\u003e: 0.88 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\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\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\u003eSeries\u003c\/strong\u003e: H1TE\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: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Normal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.108 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 6676481\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51739837661490,"sku":"6676481","price":184.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0c22a6c5a67254e355430d4bf48b183a_e1a9f125-7381-4347-819d-c75f6bb9c92c.jpg?v=1788819413","url":"https:\/\/voomisupply.com\/products\/kennametal-6676481-corner-radius-end-mill-3-8in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
