With a 3\/8 inch cutting diameter and 8 flutes, this tool delivers high feed rates and superior surface finishes in hardened steels, stainless steels, and high-temperature alloys. The 0.39 mm (0.0150 inch) corner radius reduces edge chipping and extends tool life in interrupted or continuous cuts. An AlCrN coating provides thermal and oxidation resistance, making this end mill well-suited for dry or near-dry machining environments. Licensed machinists and CNC operators in production shops and tool rooms are the primary users of this tooling.\u003c\/p\u003e\u003cp\u003eThis end mill is designed for use in vertical and horizontal machining centers running high-speed finishing and semi-finishing operations. The 3\/4 inch length of cut and 2.5 inch overall length make it appropriate for shallow-to-medium depth pocketing, profiling, and contouring. The straight cylindrical 3\/8 inch shank mounts directly into standard ER collet chucks, end mill holders, and shrink-fit toolholders. The HARVI IV series geometry targets aerospace, die and mold, and precision automotive component machining where tight tolerances and long tool life are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8-flute design enables higher feed rates and smoother finishes compared to 4- or 6-flute tools\u003c\/li\u003e\n\u003cli\u003eAlCrN coating provides oxidation and heat resistance for dry or minimum-quantity lubrication machining\u003c\/li\u003e\n\u003cli\u003eVariable helix and variable index geometry reduce harmonic vibration and chatter\u003c\/li\u003e\n\u003cli\u003e0.39 mm corner radius protects cutting edges and extends tool life on hardened workpieces\u003c\/li\u003e\n\u003cli\u003eCoolant-through capability supports internal coolant delivery for deep-pocket and high-heat applications\u003c\/li\u003e\n\u003cli\u003eChipbreaker geometry aids chip evacuation in long-run production cuts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003ePart of the KENNAMETAL HARVI IV series.

Ensure the machine spindle is fully stopped and the tool-change interlock is engaged before handling or changing tooling. Confirm holder bore cleanliness and proper runout before tightening to the holder manufacturer torque specification. This is a non-centercutting end mill and should not be used for direct plunge entry.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inches (0.375 inches)\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: 3\/4 inches (0.7500 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\u003eCorner Radius\u003c\/strong\u003e: 0.39 mm (0.0150 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlCrN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\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\u003eSeries\u003c\/strong\u003e: HARVI IV\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 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: 7102423\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51750277808434,"sku":"7102423","price":185.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f46299c8797635dd77d630aabef671d7_d418a00e-95b4-4b9d-aa22-b3f4614fd34e.jpg?v=1788914617","url":"https:\/\/voomisupply.com\/products\/kennametal-7102423-corner-radius-end-mill-3-8-in-8-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
