Built on the JS554 series platform, it features a 3\/4-inch diameter, a 1-1\/2-inch length of cut, and a 0.76 mm (0.030 inch) corner radius that reduces stress concentration at the cutting edge and extends tool life. The 48-degree high-helix spiral flute geometry promotes aggressive chip evacuation and smooth cutting action. SIRON-A coating provides thermal resistance and surface hardness, making this tool well-suited for demanding applications in steel, stainless steel, cast iron, and high-temperature alloys. Machinists and CNC operators in production and job-shop environments are the primary users.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for roughing operations on steel, stainless steel, cast iron, hard materials, high-temperature alloys, and non-ferrous metals. The right-hand cut, right-hand flute direction, and centercutting capability allow it to be used in plunge-entry and full-profile milling operations. The straight-cylindrical shank suits standard ER collet chucks and end mill holders commonly found on vertical and horizontal machining centers. The single-end, standard-length configuration fits most conventional tool-length requirements in production milling setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.76 mm (0.030 inch) corner radius reduces edge chipping and workpiece stress concentration\u003c\/li\u003e\n\u003cli\u003eSIRON-A coating delivers high thermal resistance and wear protection for extended tool life\u003c\/li\u003e\n\u003cli\u003e48-degree high-helix spiral flutes promote efficient chip evacuation in deep cuts\u003c\/li\u003e\n\u003cli\u003eCentercutting design enables plunge milling and slot entry without a pilot hole\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate supports tight tolerances and rigid cutting performance\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and flute direction compatible with standard CNC spindle setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct application tool for use in standard 3\/4-inch straight-cylindrical shank tool holders on vertical and horizontal CNC machining centers. Compatible workpiece materials include steel, stainless steel, cast iron, hard materials, high-temperature alloys, and non-ferrous metals per SECO JS554 series application guidelines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician following standard tooling change procedures. Ensure the machine spindle is fully stopped and the control is in a safe state before inserting or removing the tool. Use a calibrated torque wrench when securing the collet nut or end mill holder to avoid over-clamping the shank. Verify runout against the TIR maximum of 0.0004 inch using a dial indicator before starting the machining cycle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\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: 1-1\/2 inches (1.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.76 mm (0.030 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\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\u003eCoating\u003c\/strong\u003e: SIRON-A\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\u003eFlute Type\u003c\/strong\u003e: Spiral, 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\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.00080 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.04\/-0.06 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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Hard Material, High-Temperature Alloy, Non-Ferrous Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: JS554\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.83 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 02711647\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560279638322,"sku":"02711647","price":830.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6c75dd86476a7d4832e9534226134189.jpg?v=1786450057","url":"https:\/\/voomisupply.com\/products\/seco-02711647-corner-radius-end-mill-3-4-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
