Part of the SECO Series A345, it features a 3\/4-inch cutting diameter, a 3-1\/4-inch length of cut, and a 6-inch overall length, classifying it as a long-length end mill. The 45-degree helix angle promotes efficient chip evacuation and smooth cutting action, which is particularly effective in aluminum and other gummy non-ferrous alloys. Three spiral flutes and a bright uncoated finish make this tool well suited for applications where surface finish and chip flow are priorities. Machinists and CNC operators install this tool in vertical machining centers, knee mills, and similar equipment.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in aluminum, copper, brass, and other non-ferrous materials where a long reach and large depth of cut are required. The single-end, centercutting design allows plunge entry as well as peripheral and slot milling operations. It is appropriate for both production and job-shop environments where a long-length reach is necessary to access deep features, pockets, or cavities in workpieces. The straight 3\/4-inch shank seats directly into standard ER or end mill holders designed for 3\/4-inch bore retention.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance in non-ferrous cutting\u003c\/li\u003e\n  \u003cli\u003e45-degree helix angle promotes rapid chip evacuation in aluminum and soft metals\u003c\/li\u003e\n  \u003cli\u003e3-1\/4-inch length of cut provides extended reach into deep pockets and cavities\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry enables plunge milling as well as slot and peripheral cutting\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish for optimal performance in aluminum and non-ferrous alloys where coating adhesion is unnecessary\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide end mill for Series A345 applications; suitable for use in standard 3\/4-inch end mill holders, collet chucks, and shrink-fit holders compatible with a 3\/4-inch straight shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or CNC operator; the machine spindle must be fully stopped and the tool-change procedure followed before seating or removing the end mill from its holder. Ensure the holder bore is clean and free of chips before inserting the shank, and torque the retention screw or collet nut per the holder manufacturer specification. Verify runout against the published TIR maximum of 0.0005 inches after installation using a dial test indicator before beginning a cut. Do not exceed the rated depth of cut or feed rate for the workpiece material to avoid tool breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\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\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\u003eLength of Cut\u003c\/strong\u003e: 3-1\/4 inches (3.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 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\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.0600 to -0.0600 inches\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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\u003eTIR Maximum\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A345\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: 0.01 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: 17003171\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558210273586,"sku":"17003171","price":412.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e39ffcef59c3778b0674908b95ca55de_65561395-1c29-4864-a30d-16a414e3125b.jpg?v=1786406259","url":"https:\/\/voomisupply.com\/products\/seco-17003171-square-end-mill-3-4-inch-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
