It features a 1\/2 inch mill diameter with a 0.0300 inch corner radius, a 4-flute geometry, and a TiAlN coating for extended tool life under high-heat cutting conditions. The cutter runs in a right-hand cutting direction with a variable helix and variable index configuration, which helps reduce chatter and improve surface finish. With a 5\/8 inch length of cut and a 3-1\/8 inch extended reach, this end mill suits deep-pocket and high-reach operations. It is single-end and centercutting, allowing plunge entry directly into the workpiece. Licensed machinists and CNC operators in job shops and production environments are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis end mill is built for milling stainless steel as its primary workpiece material, where the TiAlN coating provides heat resistance and wear protection at elevated cutting temperatures. The extended reach and 5 inch overall length make it suitable for deep-cavity profiling, contouring, and finish milling passes on stainless components. The Weldon flat shank with a 1\/2 inch shank diameter provides positive drive and reduces pullout risk in high-torque cuts. The 0.4800 inch neck diameter allows clearance in tight areas without sacrificing rigidity. Series STRN440 identifies this tool within the SECO extended-reach carbide end mill family.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.0300 inch corner radius with tolerance of plus 0.00100 to minus 0.00100 inch for consistent edge prep\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating for high-temperature wear resistance in stainless steel and similar hard materials\u003c\/li\u003e\n  \u003cli\u003eVariable helix and variable index geometry reduces vibration and chatter during aggressive cuts\u003c\/li\u003e\n  \u003cli\u003eExtended reach design with 3-1\/8 inch reach length suits deep-cavity and long-overhang applications\u003c\/li\u003e\n  \u003cli\u003eCentercutting capability allows direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank provides positive drive and minimizes pullout in high-torque operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide corner radius end mill in Series STRN440, suitable for use in standard 1\/2 inch end mill holders or Weldon-style side-lock holders.

Ensure the spindle is fully stopped and the machine is in a safe state before tool changes. Do not exceed the tool manufacturer's recommended speeds and feeds for stainless steel to avoid premature coating wear or edge chipping. Inspect the corner radius for wear regularly, as corner radius end mills are sensitive to chipping at the corner during interrupted cuts.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: plus 0.000000 \/ minus 0.002000 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0300 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: plus 0.00100 to minus 0.00100 inch\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: 5\/8 inch (0.6250 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: plus 0.0600 \/ minus 0.0600 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: minus 0.0001 to minus 0.0004 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.4800 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 3-1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\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\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: STRN440\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 17002069\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558470648114,"sku":"17002069","price":302.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/09ef9899586f5e098a1837c0bc3db57a.jpg?v=1786413141","url":"https:\/\/voomisupply.com\/products\/seco-17002069-corner-radius-end-mill-1-2-in-4-flute-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
