It features a 4 mm cutting diameter, a 0.20 mm corner radius, and three right-hand spiral flutes with a 48-degree high helix angle. The cutting length is 10 mm with an overall length of 55 mm and a 6 mm straight-cylindrical shank. A SIRON-A coating provides thermal and wear resistance during aggressive cuts in ferrous and non-ferrous materials. This is a single-end, centercutting tool suited for milling, slotting, and profiling operations on CNC machining centers.\u003c\/p\u003e\n\u003cp\u003eThis end mill is designed for short-length, extended-reach applications where a reduced neck diameter is needed to access deeper features without sacrificing rigidity at the shank. The JS553 series targets roughing and semi-finishing passes in steel, stainless steel, cast iron, hard materials, high-temperature alloys, and non-ferrous metals. It is appropriate for use in production shops, tool rooms, and job shops running modern CNC vertical or horizontal machining centers where consistent edge life and dimensional accuracy are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4 mm cutting diameter with a 0.20 mm corner radius for controlled edge blending and reduced chipping risk\u003c\/li\u003e\n  \u003cli\u003eThree right-hand spiral flutes at 48-degree high helix for efficient chip evacuation and smooth surface finish\u003c\/li\u003e\n  \u003cli\u003eSIRON-A coating delivers elevated heat and abrasion resistance, extending tool life in difficult-to-machine alloys\u003c\/li\u003e\n  \u003cli\u003eCentercutting design permits plunge entry and ramping operations\u003c\/li\u003e\n  \u003cli\u003eExtended-reach geometry with 11.70 mm reach length and 4 mm neck diameter for deep-feature access\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides stiffness and dimensional stability under high cutting loads\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThe SECO 02733911 belongs to the JS553 series and is suited for machining steel, stainless steel, cast iron, hard materials, high-temperature alloys, and non-ferrous metals as specified by material codes P, M, K, H, S, and N.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified CNC machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Use a precision collet or end mill holder matched to the 6 mm shank diameter and verified to the h5 shank tolerance for proper runout control. Follow the tool manufacturer's recommended speeds and feeds for the specific workpiece material and do not exceed the rated cutting parameters for this tool geometry.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 4.00 mm (0.1575 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.20 mm (0.0079 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: 10.00 mm (0.3937 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 55.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 4.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 11.70 mm\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 Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: SIRON-A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: +0.02 to -0.02 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.02 \/ -0.03 mm\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 Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Short\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\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\u003eWeight\u003c\/strong\u003e: 0.04 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: 02733911\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51562906255666,"sku":"02733911","price":94.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d2d3a182a581a94da8617feacf7d7ddf.jpg?v=1786486504","url":"https:\/\/voomisupply.com\/products\/seco-02733911-corner-radius-end-mill-4mm-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
