Built from micrograin solid carbide and finished with an AlTiN coating, this tool handles steel, stainless steel, cast iron, high-temperature alloys, aluminum and non-ferrous metals, and hardened materials. The 5-flute geometry with a 45-degree spiral helix angle promotes aggressive chip evacuation and smooth surface finishes. At 0.4375 inches (7\/16 in) in diameter with a 2-inch length of cut, it is well suited to full-depth slotting, profiling, and shoulder milling in production environments where tool life and dimensional accuracy are critical.\u003c\/p\u003e\n\u003cp\u003eThe 17003608 belongs to SECO Series S545 and targets production machining applications across a wide range of workpiece materials. Its right-hand cut, right-hand flute spiral configuration is the standard orientation for most CNC vertical and horizontal machining setups. The 0.4375-inch straight shank fits standard collet chucks and end mill holders sized for 7\/16-inch tooling. It is a regular-length tool at 4 inches overall, making it a practical choice for the majority of pocket, slot, and contour operations that do not require extended reach.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for high wear resistance and rigidity\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating for elevated heat resistance in ferrous and hardened material machining\u003c\/li\u003e\n  \u003cli\u003e5-flute design increases feed rates and surface finish quality versus 4-flute equivalents\u003c\/li\u003e\n  \u003cli\u003e45-degree helix angle promotes smooth cutting action and efficient chip flow\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting geometry allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand spiral flute — standard orientation for CNC milling setups\u003c\/li\u003e\n  \u003cli\u003eTight tolerances: diameter -0.0000\/-0.0020 in, shank -0.0001\/-0.0004 in, TIR max 0.0005 in\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and manual mills accepting a 7\/16-inch straight shank; compatible with ER collet chucks, shrink-fit holders, and end mill holders sized for 0.4375-inch shank tooling.

Seat the straight shank fully into the holder and torque the collet nut or set screw to the holder manufacturer's specification. Verify runout against the 0.0005-inch maximum TIR before beginning a production run. Inspect cutting edges for chipping after use on hardened or abrasive workpiece materials, as edge condition directly affects dimensional accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.4375 inches (7\/16 in)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4375 inches (7\/16 in)\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\u003eCut 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\u003eExtended Reach\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\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: 0.27 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: 17003608\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557901205810,"sku":"17003608","price":179.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b54be523fae4744bf48bfc7a307f19ca.jpg?v=1786397782","url":"https:\/\/voomisupply.com\/products\/seco-17003608-square-end-mill-7-16-in-5-flute-altin-s545","provider":"Voomi Supply","version":"1.0","type":"link"}
