Built from micrograin solid carbide and coated with AlTiN (aluminum titanium nitride), it delivers hardness retention and heat resistance during aggressive cuts. The 5-flute geometry with a 45-degree right-hand helix provides efficient chip evacuation and a smooth surface finish. At 0.5 inches in diameter with a 1.25-inch length of cut and 3-inch overall length, it fits standard toolholding setups used in milling centers across production and job shop environments. This tool is center-cutting and runs in a right-hand cutting direction with a straight shank.\u003c\/p\u003e\u003cp\u003eThis end mill is engineered for machining steel, stainless steel, cast iron, high-temperature alloys, aluminum and non-ferrous metals, and hardened materials. It fits the ISO material group classifications P, M, K, S, N, and H, making it a versatile choice for shops running mixed workpiece materials on CNC vertical or horizontal machining centers. The Series S545 designation targets applications where tool life and edge stability under high-speed or high-feed conditions are a priority. It is suited for slotting, profiling, and peripheral milling passes where a 5-flute carbide tool is specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide substrate for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eAlTiN coating provides oxidation resistance and hardness at elevated cutting temperatures\u003c\/li\u003e\n\u003cli\u003e5 right-hand spiral flutes with 45-degree helix for efficient chip flow and reduced chatter\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows plunge entry without a pilot hole\u003c\/li\u003e\n\u003cli\u003eStraight 0.5-inch shank fits standard ER and hydraulic toolholders\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of -0.0000 \/ -0.0020 inches ensures consistent fit and finish\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tooling option for CNC milling applications requiring a 0.5-inch diameter, 5-flute solid carbide square end mill with a straight shank in the SECO Series S545 family.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully powered down and the tool carousel is in a safe state before changing tooling. Verify toolholder runout does not exceed the 0.0005-inch maximum TIR specification before committing to production cuts. Confirm proper torque on collet nuts or set screws per the toolholder manufacturer's guidelines.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: S545\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 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\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\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\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\u003eMaximum TIR\u003c\/strong\u003e: 0.0005 inches\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\u003eWeight\u003c\/strong\u003e: 0.27 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: 17003612\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558000492850,"sku":"17003612","price":134.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b54be523fae4744bf48bfc7a307f19ca_8ae8239e-23c2-4565-92e7-ec0eb1f833b9.jpg?v=1786400532","url":"https:\/\/voomisupply.com\/products\/seco-17003612-square-end-mill-0-5in-5-flute-carbide-s545","provider":"Voomi Supply","version":"1.0","type":"link"}
