Built to Series AN345 specifications, this single-end tool features a 3\/8 inch mill diameter, a 1\/2 inch length of cut, and a 45-degree helix angle optimized for efficient chip evacuation in soft and gummy materials. The micrograin carbide substrate provides edge stability at higher feed rates. With a 4 inch overall length and 2-1\/8 inch reach, this is a long-reach configuration suited for pocketing, slotting, and profiling operations where standard-length tools cannot access the workpiece geometry. It is installed and used by CNC machinists and tool-and-die professionals.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for machining aluminum, brass, copper, plastics, and other non-ferrous materials (ISO material group N). Its centercutting geometry allows plunge entry directly into the workpiece. The bright uncoated finish is appropriate where coatings may react with certain non-ferrous alloys or where re-sharpening is a priority. The 3\/8 inch straight shank fits standard ER collets, end mill holders, and shrink-fit tooling used on vertical and horizontal CNC machining centers as well as manual knee mills.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3 flutes with 45-degree right-hand spiral helix for aggressive chip clearance in non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eCentercutting design enables direct plunge milling without a pre-drilled entry hole\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for edge retention and dimensional consistency\u003c\/li\u003e\n\u003cli\u003eLong-reach configuration with 2-1\/8 inch reach and 4 inch overall length for deep-cavity access\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish compatible with aluminum and non-ferrous workpieces\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute geometry for conventional CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a Series AN345 replacement and standard fitment for CNC machining centers and manual mills using 3\/8 inch straight-shank toolholders, ER collets, or shrink-fit systems.

Ensure the spindle is fully stopped and the machine is in an e-stop or lockout-tagout state before inserting or removing tooling. Confirm the collet or toolholder bore is clean and within specified runout tolerance before tightening; the maximum TIR for this tool is 0.0005 inches. Follow machine tool manufacturer torque specifications for the toolholder type in use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/2 inch (0.5000 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: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\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\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 2-1\/8 inches\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 (ISO Group N)\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 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\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.0600 to -0.0600 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\u003eSeries\u003c\/strong\u003e: AN345\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 17000015\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557285626162,"sku":"17000015","price":143.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d0da64393846cdd954aa8d000ede17a7.jpg?v=1786385215","url":"https:\/\/voomisupply.com\/products\/seco-17000015-square-end-mill-3-8-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
