Built from micrograin solid carbide and coated with AlTiN (Aluminum Titanium Nitride), it delivers strong wear resistance and heat tolerance across a broad range of workpiece materials. The tool features a 5-flute, 45-degree helix spiral flute geometry with centercutting capability, allowing plunge entry as well as conventional and climb milling. At 0.375 inches in diameter with a 0.5-inch length of cut and 2-inch overall length, it fits the stub length category and suits applications where rigidity and reduced tool deflection are priorities.\u003c\/p\u003e\u003cp\u003eThis end mill is rated for use on steel, stainless steel, cast iron, high-temperature alloys, aluminum and non-ferrous materials, and hardened materials. It is a straight-shank, right-hand cut, right-hand flute tool in the SECO S545 series. Typical applications include profiling, slotting, and finishing passes in CNC machining centers and manual mills where tight tolerances and surface finish quality are required in shop, job, and production environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for improved rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eAlTiN coating provides heat and oxidation resistance for dry or semi-dry cutting\u003c\/li\u003e\n\u003cli\u003e5 flutes with 45-degree right-hand helix for efficient chip evacuation and surface finish\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge milling as well as lateral entry\u003c\/li\u003e\n\u003cli\u003eStub length profile reduces deflection in tight-clearance setups\u003c\/li\u003e\n\u003cli\u003eStraight shank, right-hand cut and flute direction, compatible with standard collet and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide end mill replacement within the SECO S545 series, suitable for use with standard 3\/8-inch collet chucks, ER collets, and end mill holders in CNC and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and locked out before changing tooling. Verify collet or holder bore diameter matches the 0.375-inch shank before securing. Follow machine manufacturer torque guidelines when tightening the collet nut, and confirm tool runout against the specified TIR maximum of 0.0005 inches before beginning a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5 inches (1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\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\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\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\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\u003eLength Type\u003c\/strong\u003e: Stub\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, High-Temp Alloy, Aluminum and Non-Ferrous, Hardened Materials\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 17003600\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558156697906,"sku":"17003600","price":82.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b54be523fae4744bf48bfc7a307f19ca_0b311861-10c7-42d8-bb4e-82a45694e3d7.jpg?v=1786404788","url":"https:\/\/voomisupply.com\/products\/seco-17003600-square-end-mill-3-8-in-5-flute-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
