It features a 5\/8 inch (0.625 inch) cutting diameter, a 0.03 inch corner radius, and four right-hand spiral flutes with a high helix angle for efficient chip evacuation. The tool carries a PVD-applied AlTiN coating that provides thermal resistance and wear protection at elevated cutting temperatures. At 3 inches overall length with a 3\/4 inch length of cut, this is a long-reach, single-end, centercutting design suited for CNC machining centers. It is intended for use by machinists and tooling professionals in production or job-shop environments.\u003c\/p\u003e\u003cp\u003eThis end mill is rated for roughing and finishing operations across a broad range of workpiece materials including steel, stainless steel, cast iron, superalloys, titanium, and hard materials. The UADE series designation indicates a submicron carbide substrate grade formulated for toughness and edge retention in difficult-to-machine alloys. The straight cylindrical shank measures 5\/8 inch in diameter and is compatible with hydraulic sleeve toolholders. Its extended-reach geometry makes it well suited for accessing deeper features such as pockets, slots, and stepped profiles where standard-length tools cannot reach.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide submicron-grade substrate for toughness and edge retention in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating provides oxidation resistance and extends tool life at high cutting speeds\u003c\/li\u003e\n\u003cli\u003e0.03 inch corner radius reduces stress concentration at the cutting edge and improves surface finish at pocket floors\u003c\/li\u003e\n\u003cli\u003eFour right-hand spiral flutes with high helix angle for smooth cutting action and efficient chip removal\u003c\/li\u003e\n\u003cli\u003eCentercutting design enables plunge entry and ramping operations\u003c\/li\u003e\n\u003cli\u003eExtended-reach geometry with 3\/4 inch length of cut on a 3 inch overall length for deep-feature access\u003c\/li\u003e\n\u003cli\u003eCompatible with HC 1\/2 through HC 1 1\/4 hydraulic sleeve toolholders with inch bores, and HC 20M through HC 32M metric sleeves with inch bores\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with HC 1\/2 through HC 1 1\/4 hydraulic sleeves with inch bores and HC 20M through HC 32M hydraulic sleeves metric with inch bores.

The machine spindle must be powered down and brought to a complete stop before changing or setting tooling. Ensure the shank is fully seated and properly torqued in the toolholder per the toolholder manufacturer specifications. Verify runout with a dial indicator after setup, as excessive runout will accelerate wear and degrade surface finish on this tool class.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inches (0.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inches (0.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\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\u003eCorner Radius\u003c\/strong\u003e: 0.0300 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: High\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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\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\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 \/ -0.00043 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\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\u003eSeries\u003c\/strong\u003e: UADE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.46 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 8.5 inches L x 1.8 inches W x 1.8 inches H\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: 4079266\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51733368734002,"sku":"4079266","price":470.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e4d2c371aa097896a385e795d9c1c594_7c3580e2-4e1a-406d-a2de-9456af562fef.jpg?v=1788754778","url":"https:\/\/voomisupply.com\/products\/kennametal-4079266-corner-radius-end-mill-5-8-in-4-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
