It features an 8-flute geometry with a variable helix angle of 35 degrees and an AlCrN coating for extended tool life under high-heat conditions. The corner radius measures 0.06 inches (1.52 mm), reducing stress concentration at the cutting edge. With a 0.5-inch diameter and a 2.0-inch length of cut, this tool is suited for semi-finishing and finishing passes in deep-cavity and peripheral milling operations. Licensed machinists and CNC programmers in production shops will find this tool well matched to difficult-to-machine alloys and hardened steels.\u003c\/p\u003e\u003cp\u003eThis end mill is used in CNC machining centers for milling ferrous and difficult alloy materials where tool stability and surface finish consistency are critical. The coolant-through capability supports high-speed material removal by delivering coolant directly to the cutting zone, reducing heat buildup and chip packing in deep-pocket or slotting applications. The chipbreaker geometry helps manage chip evacuation in extended-reach or multi-pass operations. It is a single-end, non-centercutting tool, meaning it is not intended for plunge drilling and should be ramped or helical-interpolated into material.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8-flute solid carbide construction for rigidity and high feed rates\u003c\/li\u003e\n\u003cli\u003eAlCrN coating for heat resistance and extended tool life in alloy steels\u003c\/li\u003e\n\u003cli\u003eVariable helix design reduces chatter and harmonic vibration\u003c\/li\u003e\n\u003cli\u003eCoolant-through capability for chip evacuation in deep-pocket milling\u003c\/li\u003e\n\u003cli\u003eChipbreaker geometry improves chip control during extended cuts\u003c\/li\u003e\n\u003cli\u003eCorner radius end type reduces edge chipping and improves surface finish\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-specified tool in the KENNAMETAL HARVI IV series; catalog reference HA4R8RA0500X200HAR060D. Confirm spindle taper, collet size, and machine power requirements before installation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the control is in a safe state before loading or unloading the tool. Use a properly sized precision collet or hydraulic chuck matched to the 0.5-inch straight-cylindrical shank to maintain runout within acceptable limits. This tool is non-centercutting and requires a ramp, arc, or helical entry path  -  direct axial plunging will damage the cutting edges.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches (12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.0 inches (50.80 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.0 inches (101.60 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches (12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.06 inches (1.52 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 degrees variable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlCrN\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\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HARVI IV\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.34 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: 7102869\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51739678998834,"sku":"7102869","price":353.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3419667a948f2c24a557212fe4b2c64a_661cdee6-0c8a-4a5a-8ec5-98886526f6ae.jpg?v=1788817689","url":"https:\/\/voomisupply.com\/products\/kennametal-7102869-corner-radius-end-mill-0-5in-8-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
