Built to the HPHV series specification, this single-end tool features a 1\/2-inch mill diameter with an AlTiN PVD coating that extends tool life when cutting steel, stainless steel, cast iron, and hard materials. The 0.030-inch corner radius reduces stress concentration at the cutting edge, supporting both roughing and finishing operations in a single tool. Four right-hand spiral flutes with a variable index geometry help minimize chatter and improve surface finish. This head is intended for professional machinists and toolroom technicians working in production or job-shop CNC environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill head is suited for use in CNC machining centers where high-feed, high-velocity milling strategies are employed. Its Weldon Flat shank and h6 shank diameter tolerance make it compatible with standard Weldon-style toolholders used in vertical and horizontal milling setups. It is appropriate for applications involving steel, stainless steel, non-ferrous metals, and hard materials, covering material codes P, M, K, and H. The standard-length flute configuration and 1-inch length of cut make it a practical choice for general-purpose slotting, profiling, and contouring where edge integrity and consistent corner geometry are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.030-inch corner radius reduces cutting-edge chipping and extends tool life in interrupted cuts\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating provides thermal resistance for dry or semi-dry high-speed milling\u003c\/li\u003e\n  \u003cli\u003eVariable index flute spacing reduces harmonic vibration and chatter during aggressive cuts\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction (material grade KCPM15) delivers rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry allows plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eWeldon Flat shank with h6 tolerance ensures secure clamping and accurate runout in standard toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard Weldon-style toolholders accepting a 1\/2-inch shank.

Confirm the toolholder bore and retention screw are clean and free of debris before seating the shank. Torque the Weldon set screw to the toolholder manufacturer's specification  -  do not estimate. Verify runout with a dial indicator before beginning a cut, and ensure spindle RPM and feed rate are set per the applicable speeds-and-feeds data for the workpiece material and depth of cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5000 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: 1.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0300 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 1.0000 inches\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: KCPM15\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\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\u003eHelix Style\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\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\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, Non-Ferrous Metal, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HPHV\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturers Catalog Number\u003c\/strong\u003e: HPHV500S4100R030\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 4071910\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51739597209906,"sku":"4071910","price":248.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f8871f740774cdd8f519c4571e5928cb.jpg?v=1788816746","url":"https:\/\/voomisupply.com\/products\/kennametal-4071910-corner-radius-end-mill-head-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
