It carries a 5\/16 inch diameter, a 0.015 inch corner radius, and three right-hand spiral flutes with a high helix angle of 48 degrees. The cutting edge is center-cutting and single-end, allowing plunge entry. The SIRON-A (AlCrN-based) coating provides thermal resistance and wear protection for extended tool life in abrasive and high-heat applications. This tool is suited for machinists and tool-and-die professionals working in production or job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThe 02712693 is configured for short-length, roughing-style material removal operations. Its 5\/8 inch length of cut, 2.5 inch overall length, and straight cylindrical 5\/16 inch shank make it compatible with standard ER and shrink-fit collet toolholders. It is well suited for slotting, profiling, and corner-radius contouring passes in ferrous and exotic alloy workpieces where edge integrity and chip evacuation are priorities. The right-hand cutting direction and spiral flute geometry support efficient chip flow in both climb and conventional milling strategies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide substrate for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eSIRON-A coating (AlCrN-based) enhances thermal stability and reduces tool wear at elevated cutting speeds\u003c\/li\u003e\n  \u003cli\u003e0.015 inch corner radius reduces stress concentration at the cutting edge and improves surface finish at part corners\u003c\/li\u003e\n  \u003cli\u003e48-degree high helix angle promotes efficient chip evacuation and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eSingle-end, short-length configuration suitable for rigidity-critical roughing passes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with steel, stainless steel, cast iron, hard materials, high-temperature alloys, and non-ferrous metals as stated by the manufacturer.

Ensure the toolholder collet bore and shank diameter are matched within specified tolerances before tightening. Verify spindle runout does not exceed the 0.0004 inch TIR maximum for this tool. Follow machine tool manufacturer guidelines for feed, speed, and depth-of-cut parameters appropriate to the workpiece material and machine rigidity.\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 inches (0.3126 inches decimal)\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: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 5\/8 inches (0.625 inches decimal)\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: 5\/16 inches (0.3126 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 48 degrees (High Helix)\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 End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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 Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: SIRON-A (AlCrN-based)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Hard Material, High-Temperature Alloy, Non-Ferrous Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.03 \/ -0.04 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: JS553\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\u003eWeight\u003c\/strong\u003e: 0.13 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: 02712693\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560099152178,"sku":"02712693","price":120.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2b5a583c770789f87851375a3d31f499_1c838010-f923-4d2f-9f98-964d7f0a7295.jpg?v=1786446495","url":"https:\/\/voomisupply.com\/products\/seco-02712693-corner-radius-end-mill-5-16in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
