It features a 1\/4 inch cutting diameter, a 1\/2 inch length of cut, and four flutes arranged in a variable-helix spiral configuration. The variable helix geometry reduces harmonic vibration and improves chip evacuation during both roughing and finishing passes. The micrograin carbide substrate is finished with an AlTiN (aluminum titanium nitride) PVD coating, which improves heat resistance and extends tool life in abrasive and high-temperature cutting environments. This tool is part of the SECO STB440.2 series and is suited for machinists working in job shop and production environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in CNC milling centers and manual mills where precision profiling, contouring, and slotting in hard or exotic workpiece materials is required. Its short length type and straight-cylindrical shank make it a practical choice for setups requiring rigidity and minimal overhang. Primary target materials are ISO M (stainless steel), ISO S (superalloys and titanium), and ISO H (hardened materials). The single-end configuration and right-hand cutting and flute direction are standard for conventional CNC milling operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eVariable-helix flute geometry reduces chatter and improves surface finish\u003c\/li\u003e\n  \u003cli\u003eAlTiN PVD coating provides oxidation resistance for dry and semi-dry cutting in hard materials\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for improved wear resistance and edge sharpness\u003c\/li\u003e\n  \u003cli\u003eFour-flute design supports both roughing and finishing in a single tool\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand spiral with straight-cylindrical shank for standard collet or end mill holder mounting\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through requirement — compatible with external coolant or dry cutting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and milling machines accepting a 1\/4 inch straight-cylindrical shank.

Secure the shank in a precision collet chuck or end mill holder rated for the shank diameter tolerance of -0.0001 to -0.0004 inches. Ensure the machine spindle and tool holder are clean and free of runout-inducing debris before seating the tool. Confirm TIR does not exceed 0.0005 inches at setup to maintain dimensional accuracy and edge life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2500 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5000 inches (1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5000 inches (2-1\/2 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2500 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.1250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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: AlTiN (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Variable Helix\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: Straight-Cylindrical\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel; Superalloys and Titanium; Hard Material (ISO M, S, H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0020 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\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum TIR\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: STB440.2\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\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: 03083826\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558283641138,"sku":"03083826","price":77.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a7ec4b1800d1ab409516702a77ae4bec.jpg?v=1786408439","url":"https:\/\/voomisupply.com\/products\/seco-03083826-ball-end-mill-1-4-in-4-flute-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
