It carries a 7\/16 inch diameter, a 1 inch length of cut, and a 0.0200 inch corner radius, making it well suited for both roughing and finishing passes in hardened and high-strength materials. The AlTiN physical vapor deposition (PVD) coating adds thermal resistance and extends tool life at elevated cutting temperatures. With three flutes, a right-hand spiral flute direction, and a 35-degree medium helix, the tool balances chip evacuation with cutting stability across a range of CNC milling applications. It ships as a single-end, centercutting tool in the SECO S335 series.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in CNC machining centers and manual mills where corner rounding, profiling, and slotting operations require a durable, coated carbide solution. The Weldon flat shank is compatible with standard side-lock toolholders, providing positive radial drive without slippage under aggressive feeds. Its short length type and coarse pitch geometry make it practical for stable cuts in tough ferrous and exotic alloy workpieces. Machinists and CNC operators working in job shops, aerospace, and general metalworking will find this tool appropriate for tight-tolerance finishing work as well as productive roughing cycles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlTiN PVD coating provides heat resistance for cutting steel, stainless steel, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003e0.0200 inch corner radius reduces stress concentration at the cutting edge for improved tool life\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction delivers rigidity and dimensional stability at high spindle speeds\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank for secure positive-drive engagement in side-lock toolholders\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flutes with 35-degree medium helix balance chip flow and radial cutting forces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard Weldon flat side-lock toolholders accepting a 7\/16 inch shank diameter.

Ensure the machine spindle is fully stopped and the toolholder is clean and free of debris before seating the end mill. Verify shank engagement depth meets the toolholder manufacturer minimum before tightening the set screw against the Weldon flat. Confirm runout does not exceed the TIR maximum of 0.0005 inch after installation to maintain dimensional accuracy and tool life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/16 inch (0.4375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch (1.0000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0200 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/4 inches (2.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7\/16 inch (0.4375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 degrees\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: AlTiN (PVD)\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\u003eShank Type\u003c\/strong\u003e: Weldon Flat\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\u003eLength Type\u003c\/strong\u003e: Short\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\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 Material\u003c\/strong\u003e: Steel; Stainless Steel; Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: +0.00100 to -0.00100 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0020 \/ 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: -0.0600 \/ 0.0600 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: S335\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\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: 17003419\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51561844212018,"sku":"17003419","price":111.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cce93008815557903013340877bce336_94449352-0ed8-4c47-ab8e-470a4f2ea783.jpg?v=1786469241","url":"https:\/\/voomisupply.com\/products\/seco-17003419-corner-radius-end-mill-7-16-in-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
