Built from micrograin solid carbide with an AlTiN coating, it carries a 0.25 inch cutting diameter, a 0.375 inch length of cut, and a 45-degree helix angle. The straight shank measures 0.25 inch in diameter and the overall length is 2 inches. With five flutes and a right-hand spiral flute configuration, this tool is centercutting capable and suited for finishing and semi-finishing work across a wide range of workpiece materials. Licensed machinists and toolroom operators are the primary installers and users.\u003c\/p\u003e\u003cp\u003eThe 17003589 is rated for use on steel, stainless steel, cast iron, high-temperature alloys, aluminum and non-ferrous materials, and hardened materials — covering ISO material codes P, M, K, S, N, and H. The short flute length and 5-flute geometry make it well-suited for CNC machining centers and manual mills where rigidity and surface finish are priorities. It is classified as a short-length tool, which aids stability in tight setups and shallow-pocket work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide substrate for wear resistance and edge stability\u003c\/li\u003e\n\u003cli\u003eAlTiN coating supports dry and high-speed cutting in ferrous and hardened materials\u003c\/li\u003e\n\u003cli\u003e5-flute design increases feed rate potential compared to standard 4-flute end mills\u003c\/li\u003e\n\u003cli\u003e45-degree helix angle promotes smooth chip evacuation and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute configuration — standard for most CNC and manual setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit tooling solution for standard 0.25 inch collets, ER chucks, and hydraulic tool holders used in CNC machining centers and manual milling machines.

Ensure the spindle and machine are fully stopped and locked out before changing tooling. Verify runout does not exceed the 0.0005 inch TIR maximum spec after seating the tool in the holder. Coolant-through is not supported on this tool — use external coolant or dry cutting strategies as appropriate for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Micrograin Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.0015 \/ -0.0015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: S545\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 17003589\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557986599218,"sku":"17003589","price":59.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b54be523fae4744bf48bfc7a307f19ca_0d7e4db0-c644-4335-9c42-efa8b008296f.jpg?v=1786400148","url":"https:\/\/voomisupply.com\/products\/seco-17003589-square-end-mill-1-4-in-5-flute-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
