It features a 1\/4 inch diameter, a 3\/4 inch length of cut, and a 0.015 inch corner radius that reduces stress concentrations at workpiece edges and extends tool life. The 5-flute, single-end geometry with a high helix spiral flute design promotes efficient chip evacuation while maintaining a strong core. An AlTiN (aluminum titanium nitride) PVD coating provides thermal resistance and hardness, making this end mill well suited for dry or near-dry cutting conditions. Machinists and CNC operators in tool rooms, job shops, and production environments rely on this tool for both roughing and finishing passes.\u003c\/p\u003e\n\u003cp\u003eThis end mill is designed for cutting steel, stainless steel, cast iron, superalloys, titanium, and hard materials. Its 1\/4 inch straight-cylindrical shank, 2.5 inch overall length, and normal pitch make it compatible with standard collet chucks and hydraulic tool holders. It is specified for use with HC 20M through HC 32M hydraulic sleeves metric with inch bores and HC-CV Form AD holders. Right-hand flute direction and right-hand cutting direction are standard. The UCDE series designation places this tool in Kennametal's submicron carbide grade lineup, optimized for tight-tolerance finish work and intermediate-stock roughing in difficult alloys.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.015 inch corner radius reduces edge chipping and improves surface finish on workpiece corners\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating delivers high heat resistance for cutting steel, stainless steel, cast iron, superalloys, titanium, and hard materials\u003c\/li\u003e\n  \u003cli\u003e5-flute spiral geometry supports both roughing and finishing material removal in a single tool\u003c\/li\u003e\n  \u003cli\u003eSubmicron solid carbide grade provides rigidity and wear resistance at elevated cutting speeds\u003c\/li\u003e\n  \u003cli\u003eHigh helix angle promotes chip flow and reduces cutting forces in tough alloys\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical 1\/4 inch shank fits standard collets and hydraulic shrink-fit holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eSpecified for use with HC 20M through HC 32M hydraulic sleeves metric with inch bores and HC-CV Form AD tool holders.

Ensure the shank is clean and free of chips or oil contamination before seating in the collet or hydraulic holder, and torque the retention nut or holder to the tool holder manufacturer specification. Confirm runout with a dial indicator before cutting, as excessive runout accelerates wear on small-diameter carbide tools. Follow applicable shop safety standards and machine manufacturer guidelines for high-speed milling operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\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: 0.250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix\u003c\/strong\u003e: High (38 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide, Submicron Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: UCDE\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: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys, Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 3580840\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51749410603314,"sku":"3580840","price":121.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/daadb2cd38e98818b8d41f2339b62296_de83a06b-f253-44f2-afcd-dce51b54473b.jpg?v=1788905725","url":"https:\/\/voomisupply.com\/products\/kennametal-3580840-corner-radius-end-mill-1-4-in-5-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
