It features an 8-flute configuration with a 0.030-inch (0.77 mm) corner radius, a 0.5-inch cutting diameter, and a 1.25-inch length of cut. The variable helix and variable index geometry reduce harmonic vibration during aggressive cuts, while the AlCrN coating provides thermal resistance and extended tool life in abrasive materials. Coolant-through capability supports chip evacuation in deep-cavity and high-feed operations. Licensed machinists and CNC tooling technicians are the primary installers and operators.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for high-speed finishing and semi-finishing passes on hardened steels, stainless alloys, and other difficult-to-machine materials in both production and job-shop environments. The single-end, right-hand cutting and right-hand flute direction are standard for conventional CNC machining center setups. The straight cylindrical shank fits standard collets and end mill holders with a 0.5-inch bore. No centercutting geometry means this tool is not intended for plunge entry.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8-flute solid carbide construction for high metal removal rates and surface finish quality\u003c\/li\u003e\n\u003cli\u003eVariable helix and variable index design reduces chatter and vibration in tough materials\u003c\/li\u003e\n\u003cli\u003eAlCrN coating delivers high-temperature resistance and reduced tool wear\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports chip evacuation in deep cuts and high-feed applications\u003c\/li\u003e\n\u003cli\u003e0.030-inch corner radius protects cutting edges and reduces stress concentration at part corners\u003c\/li\u003e\n\u003cli\u003eChipbreaker geometry included for improved chip control in long-flute cuts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide end mill for use in CNC machining centers accepting a 0.5-inch straight cylindrical shank; part of the KENNAMETAL HARVI IV series.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a qualified machinist or CNC tooling technician. Secure the shank in a properly sized collet or end mill holder torqued to the machine tool manufacturer's specification. Confirm runout with a dial indicator before starting a production run. This tool is not center-cutting and must not be used for direct plunge entry; use a ramping or helical entry strategy instead.\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: 3.5 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: 0.030 inches (0.77 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlCrN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\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\u003eVariable Helix\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\u003eSeries\u003c\/strong\u003e: HARVI IV\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.31 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 7102857\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51738481852722,"sku":"7102857","price":331.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3419667a948f2c24a557212fe4b2c64a.jpg?v=1788800107","url":"https:\/\/voomisupply.com\/products\/kennametal-7102857-corner-radius-end-mill-8-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
