Built from micrograin solid carbide and finished with an AlTiN coating, this tool handles aggressive cuts in steel, stainless steel, cast iron, high-temperature alloys, aluminum and non-ferrous metals, and hardened materials. The 1 inch cutting diameter pairs with a 2-5\/8 inch length of cut and a 45-degree helix angle for efficient chip evacuation and stable cutting action. Licensed machinists and CNC operators reach for this tool when working on production runs that demand tight tolerances and coating durability under heat.\u003c\/p\u003e\u003cp\u003eThis end mill fits standard 1 inch straight-shank toolholders and is suited for vertical machining centers, horizontal mills, and manual knee mills where a 6 inch overall length provides adequate reach without excessive overhang. Its centercutting geometry allows plunge entry, expanding the range of operations including slot milling, profiling, and pocket roughing. The S545 series is engineered for multi-material capability, making it a practical choice for job shops running varied workpiece materials across the ISO P, M, K, S, N, and H material groups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide substrate for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN coating extends tool life in dry and semi-dry cutting conditions at elevated temperatures\u003c\/li\u003e\n\u003cli\u003e5-flute geometry increases feed rates and surface finish quality compared to 4-flute designs\u003c\/li\u003e\n\u003cli\u003e45-degree helix angle promotes smooth chip flow and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting design supports plunge milling and full-slot entry\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand spiral flute configuration for conventional CNC spindle use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 1 inch straight-shank toolholders on CNC and manual milling machines.

Verify TIR does not exceed 0.0005 inches after mounting to maintain dimensional accuracy and tool life. Secure the shank to the minimum recommended engagement depth in the toolholder and confirm all axes are zeroed before initiating a cut. Power down the spindle and engage the machine lock before changing or inspecting the tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2-5\/8 inches (2.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\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\/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\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\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\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\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: 2.5 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: 17003626\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560241004850,"sku":"17003626","price":668.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b54be523fae4744bf48bfc7a307f19ca_53714bf6-f73c-4246-b81f-c56af9a4eff8.jpg?v=1786449616","url":"https:\/\/voomisupply.com\/products\/seco-17003626-square-end-mill-1-inch-5-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
