Built from micrograin carbide, it delivers the edge retention and dimensional stability required for precise material removal. The tool features a 45-degree helix angle and a bright uncoated finish, both suited to the low-friction, high-speed demands of non-ferrous machining. With a 3\/4 inch cutting diameter and three flutes, it balances chip evacuation with rigidity. This is a single-end, centercutting tool, meaning it can plunge directly into the workpiece as well as perform peripheral milling. Machinists and CNC operators in production and job-shop environments are the primary installers of this tool.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in milling machines and CNC machining centers where aluminum, brass, copper, and similar non-ferrous workpiece materials are processed. The short flute length classification and 1-5\/8 inch length of cut make it appropriate for applications requiring stability and minimal deflection, particularly in shallow-to-moderate depth passes. The straight shank fits standard ER collet chucks, end mill holders, and similar toolholding systems common in horizontal and vertical machining setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for edge durability in non-ferrous applications\u003c\/li\u003e\n\u003cli\u003e45-degree helix angle promotes efficient chip flow in aluminum and soft metals\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows both plunge and peripheral milling operations\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish minimizes built-up edge on non-ferrous workpiece materials\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute spiral for standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eTight tolerances: mill diameter -0.0000\/-0.0020 inches, TIR maximum 0.0005 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eBelongs to SECO Series A345 and is rated for primary workpiece material code N, covering aluminum and non-ferrous metals. Designed for use in standard straight-shank toolholders with a 3\/4 inch bore. Coolant-through and extended-reach configurations are not applicable to this part number.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes must be performed with the machine spindle fully stopped and the machine placed in a locked-out, de-energized state per applicable lockout\/tagout procedures. Secure the straight shank fully within the toolholder to the recommended engagement depth for the holder type in use; insufficient engagement is a common cause of tool pullout under load. Verify runout with a dial indicator before cutting; TIR for this tool is rated at a maximum of 0.0005 inches. Handle carbide tooling carefully to avoid chipping the cutting edges during setup.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eLength of Cut\u003c\/strong\u003e: 1-5\/8 inch (1.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.0000 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\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\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\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\/-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: A345\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Classification\u003c\/strong\u003e: Short\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: 17003169\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51564110807346,"sku":"17003169","price":322.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e39ffcef59c3778b0674908b95ca55de_66d2baeb-3f42-4788-aa19-c41ae9cb5a90.jpg?v=1786511197","url":"https:\/\/voomisupply.com\/products\/seco-17003169-square-end-mill-3-4-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
