It features a 7\/32-inch (0.2188 inch) cutting diameter, a 3\/4-inch length of cut, and a 1\/4-inch straight shank, with an overall length of 2-1\/2 inches. The three-flute, spiral geometry runs at a 45-degree helix angle, promoting efficient chip evacuation and smooth cutting performance. The bright, uncoated finish and micrograin carbide construction make it well suited to high-speed passes in softer metals. This is a single-end, center-cutting tool with right-hand cut and right-hand flute orientation, installed and run by machinists and CNC operators.\u003c\/p\u003e\u003cp\u003eThis end mill is primarily intended for machining aluminum, copper, brass, and other non-ferrous alloys in both production and job-shop environments. Its center-cutting capability allows plunge entry, making it practical for pocket milling, slotting, and profiling operations on vertical and horizontal machining centers as well as manual knee mills. The compact 2-1\/2-inch overall length and 1\/4-inch shank suit it to smaller spindle toolholders and high-speed spindles where rigidity is important. It carries the Series A345 designation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance in non-ferrous applications\u003c\/li\u003e\n\u003cli\u003e3-flute spiral geometry with 45-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suited to aluminum and non-ferrous workpiece materials\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute orientation for standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eStraight 1\/4-inch shank compatible with common ER and end-mill toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a Series A345 replacement or direct-use solid carbide square end mill for applications involving aluminum and non-ferrous materials (Primary Workpiece Material Code: N).

The tool should be seated fully and evenly in a clean, properly sized collet or end-mill holder before torquing the retention mechanism to the toolholder manufacturer's specification. Verify spindle runout against the stated TIR maximum of 0.0005 inch before beginning a cut. Do not exceed the rated cutting geometry for the workpiece material, and confirm that coolant-through is not required, as this tool does not support it.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/32 inch (0.2188 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches (2.5000 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\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\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.0005 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\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\u003eSeries\u003c\/strong\u003e: A345\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: 17003139\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51564219597106,"sku":"17003139","price":60.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e39ffcef59c3778b0674908b95ca55de_8351ad37-ef47-48b9-97e0-970316a6dabb.jpg?v=1786514388","url":"https:\/\/voomisupply.com\/products\/seco-17003139-square-end-mill-7-32-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
