It features a 5\/16 inch (0.3125 inch) mill diameter, a 0.0200 inch corner radius, and three right-hand spiral flutes with a 35-degree medium helix angle. The AlTiN PVD coating provides thermal resistance and wear protection at elevated cutting temperatures. At 2 inches overall length with a 7\/16 inch length of cut, this is a stub-length tool built for rigidity and reduced deflection in aggressive passes. It is centercutting and capable of both roughing and finishing operations in a single tool.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for CNC machining centers and manual mills where tight tolerances and surface finish in hard or heat-resistant alloys are required. The S335 series designation places it within a coarse-pitch geometry optimized for chip evacuation in difficult-to-machine materials. Machinists and tool-and-die shops working aerospace, medical, and high-performance industrial components will find this tool appropriate for slotting, profiling, and plunge operations where corner edge integrity is critical. It accepts standard straight-cylindrical toolholders with a 5\/16 inch shank.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.0200 inch corner radius with tolerance of +0.0010 to -0.0010 inch for consistent edge geometry\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating for high-temperature wear resistance in steel, stainless, and superalloy cutting\u003c\/li\u003e\n  \u003cli\u003eThree right-hand spiral flutes with coarse pitch and 35-degree medium helix for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eStub length (7\/16 inch LOC, 2 inch OAL) maximizes rigidity and minimizes deflection\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides stiffness and hardness superior to HSS in demanding cuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with straight-cylindrical toolholders accepting a 5\/16 inch shank diameter.

Ensure the machine spindle is fully stopped and the tool is secured in a clean, compatible straight-cylindrical toolholder before tightening. Verify runout does not exceed the 0.0005 inch TIR maximum specification before engaging a cut. Consult the toolholder manufacturer and machine tool documentation for appropriate clamping torque and collet specifications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0200 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 7\/16 inch (0.4375 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Medium\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\u003ePitch\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\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\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\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 Material\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.0005 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: +0.0010 to -0.0010 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0020 \/ 0.0000 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: -0.0600 \/ +0.0600 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: S335\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 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: 17003412\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559431569714,"sku":"17003412","price":72.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cce93008815557903013340877bce336_5af528db-f571-4953-aced-d7a2c609c990.jpg?v=1786432304","url":"https:\/\/voomisupply.com\/products\/seco-17003412-corner-radius-end-mill-5-16-in-3-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
