Part of the AN345 series, it features a 3\/4 inch cutting diameter, a 1 inch length of cut, and a 6 inch overall length. The 45-degree helix angle promotes efficient chip evacuation in soft, gummy materials, reducing built-up edge. With three flutes and a bright\/uncoated finish, this tool delivers clean surface finishes without the added friction of a coating. The micrograin carbide substrate provides the rigidity and edge retention needed for high-speed passes in aluminum, brass, and copper. Qualified machinists and CNC operators install and run this tool in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for slot milling, profiling, and peripheral milling in aluminum, brass, copper, and other non-ferrous workpiece materials. The long-length profile and 3.5 inch reach length make it appropriate for deeper cavities and stepped features where a standard-length tool cannot reach. The centercutting geometry allows direct plunge entry without a pre-drilled start hole. Right-hand cut and right-hand flute configuration is standard for conventional CNC machining center spindles. Single-end construction is typical for production use where tool replacement is straightforward.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4 inch cutting diameter with mill diameter tolerance of +0.0000 to -0.0020 inches for consistent fit in tight-tolerance work\u003c\/li\u003e\n  \u003cli\u003e45-degree helix angle optimized for aluminum and non-ferrous chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for edge stability at higher surface footage\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish — no coating buildup that can cause material adhesion in aluminum\u003c\/li\u003e\n  \u003cli\u003eLong-length series with 3.5 inch reach for deep-cavity and stepped-feature access\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand spiral flute — compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in aluminum and non-ferrous workpiece materials (Primary Workpiece Material Code: N) as specified by the manufacturer.

Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before inserting or removing the tool from the holder. Verify collet or holder bore is free of chips and within the shank diameter tolerance range before torquing the retention nut. Do not use this tool on ferrous materials, as the uncoated bright finish and geometry are not optimized for steel or cast iron applications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.7500 inches (3\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.7500 inches (3\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 3.5 inches\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: Solid Carbide, Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum and Non-Ferrous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 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: AN345\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.2 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: 17000024\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563994677554,"sku":"17000024","price":460.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d0da64393846cdd954aa8d000ede17a7_7364a552-6ca0-4a66-a7f3-7c083c5bebfe.jpg?v=1786508628","url":"https:\/\/voomisupply.com\/products\/seco-17000024-square-end-mill-3-4-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
