It features a 3\/8-inch cutting diameter, a 0.09-inch corner radius, and four flutes ground with a high helix angle for efficient chip evacuation. The tool is coated with AlTiN (aluminum titanium nitride) via a PVD process, providing thermal resistance and extended tool life when cutting ferrous materials at elevated surface speeds. At 3 inches overall length with a 7\/8-inch length of cut, this single-end, centercutting tool is built for both roughing and finishing passes in a single setup. It is intended for use by machinists and CNC operators working in production or job-shop environments.\u003c\/p\u003e\u003cp\u003eThis end mill is engineered for cutting steel, stainless steel, cast iron, and hard materials, aligning with ISO material groups P, M, K, and H. The HPHV series designation indicates a high-pitch, high-velocity design optimized for aggressive material removal rates without sacrificing surface finish quality. The 3\/8-inch straight cylindrical shank is compatible with HC 1\/2 through HC 1 1\/4 hydraulic sleeves with inch bores, making it well-suited for use in hydraulic toolholding systems that demand precise runout control. Extended reach geometry supports reach into deeper pockets or stepped features where standard-length tooling cannot access.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.09-inch corner radius reduces stress concentration at the cutting edge and improves corner life in hardened materials\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating provides oxidation resistance and thermal stability for dry or minimal-lubrication cutting\u003c\/li\u003e\n\u003cli\u003eFour-flute, right-hand spiral geometry supports both roughing and finishing in a single tool\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eSubmicron carbide grade substrate delivers hardness and toughness for difficult-to-machine alloys\u003c\/li\u003e\n\u003cli\u003eExtended reach geometry provides access to deeper pockets and stepped workpiece features\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with HC 1\/2 through HC 1 1\/4 hydraulic sleeves with inch bores.

Power down and lock out the machine spindle before changing tooling. Confirm shank seating depth meets the minimum grip length required by the holder to prevent pullout under load. Inspect the cutting edges for chipping or wear before each use, particularly when working with hard or abrasive workpiece materials.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.09 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: 7\/8 inches (0.8750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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: High\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Normal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HPHV\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -0.002000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.00000 \/ -0.00035 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.022 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: 4047761\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51728744055090,"sku":"4047761","price":159.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e4d2c371aa097896a385e795d9c1c594_af6bab84-4afb-4458-abcc-531f67f1cf1f.jpg?v=1788695731","url":"https:\/\/voomisupply.com\/products\/kennametal-4047761-corner-radius-end-mill-3-8-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
