Built to the HPHV series specification, it carries a 0.5-inch mill diameter, a 0.06-inch corner radius, and an AlTiN PVD coating that extends tool life in high-heat cutting environments. The single-end, right-hand cutting geometry features four spiral flutes with a high helix style, supporting both roughing and finishing operations. Extended reach geometry and a Weldon flat shank make this tool well-suited for setups requiring rigid tool holding and precise radial engagement. Machinists and CNC operators working with difficult alloys will find this cutter capable of sustained performance without premature wear.\u003c\/p\u003e\n\u003cp\u003eThe 4071907 is designed for short-reach applications with a 0.625-inch length of cut and a 2.5-inch overall length. The Weldon flat shank is compatible with EM-CV Form AD holders as well as EM IN-HSK Form A tooling interfaces, making it straightforward to integrate into common CNC machining center setups. Its centercutting capability and right-hand flute direction support plunge entries and conventional profiling passes. Primary workpiece material codes P, M, K, and H indicate suitability for steel, stainless steel, cast iron, and hard material groups per ISO classification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with submicron material grade for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating reduces heat buildup and extends tool life in ferrous and hard-material applications\u003c\/li\u003e\n  \u003cli\u003e0.06-inch corner radius reduces stress concentration at the cutting edge and improves surface finish at part corners\u003c\/li\u003e\n  \u003cli\u003eFour spiral flutes with high helix style support efficient chip evacuation during roughing and finishing passes\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge milling entries without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank provides positive rotational engagement and prevents tool pullout under heavy radial loads\u003c\/li\u003e\n  \u003cli\u003eExtended reach geometry suits deep-pocket and stepped-feature machining scenarios\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 toolholders as specified by the manufacturer.

Seat the Weldon flat shank fully into the holder and tighten the set screw against the flat to the toolholder manufacturer's specified engagement. Verify runout with a dial indicator before production cuts, as excessive runout accelerates edge wear on carbide end mills. Follow shop-specific speeds, feeds, and depth-of-cut parameters for the specific workpiece material and machine capability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 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: 0.06 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: 0.625 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\u003eReach Length\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\u003eSeries\u003c\/strong\u003e: HPHV\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: High\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\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\u003eExtended Reach\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\u003ePitch\u003c\/strong\u003e: Normal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Short\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\u003eWeight\u003c\/strong\u003e: 0.1 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: 4071907\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51733596078386,"sku":"4071907","price":257.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e4d2c371aa097896a385e795d9c1c594_647b3e60-d712-44e7-bdda-e6df931a0769.jpg?v=1788756691","url":"https:\/\/voomisupply.com\/products\/kennametal-4071907-corner-radius-end-mill-0-5in-4-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
