With a 0.25 inch mill diameter, a 0.0100 inch corner radius, and three right-hand spiral flutes, it delivers a combination of roughing and finishing capability in a single tool. The high helix angle of 40 degrees promotes efficient chip evacuation and surface finish quality. The bright\/uncoated finish makes it well suited for aluminum, copper, brass, and similar non-ferrous materials where coating adhesion can cause buildup. This tool is installed by machinists and CNC operators working in job shops, production environments, and toolroom settings.\u003c\/p\u003e\u003cp\u003eThis end mill fits standard toolholder setups and is appropriate for light-to-moderate material removal on non-ferrous workpieces. The short length-of-cut geometry combined with an extended reach of 1.75 inches makes it useful in pocketing, slotting, and profiling operations where access depth is a factor. The AN340 series designation identifies it within SECOs catalog of general-purpose carbide end mills intended for both manual and CNC machining centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in non-ferrous milling\u003c\/li\u003e\n\u003cli\u003e0.0100 inch corner radius reduces stress concentration and extends tool life at corners\u003c\/li\u003e\n\u003cli\u003e3 right-hand spiral flutes with coarse pitch for efficient chip clearance\u003c\/li\u003e\n\u003cli\u003e40-degree high helix angle improves surface finish and chip evacuation\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eExtended reach of 1.75 inches supports deep pocket and restricted-access operations\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish optimized for non-ferrous and gummy materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard straight-bore cylindrical toolholders.

Ensure the machine spindle is fully stopped and the tool changer is disabled before handling or changing the end mill. Seat the straight-cylindrical shank fully in the toolholder and verify runout does not exceed the maximum TIR of 0.0005 inches before beginning a cut. Follow the toolholder manufacturer torque guidelines for set screws or collet nuts — do not over-tighten, as this can induce shank distortion on small-diameter carbide tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0100 inches\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: 0.3125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.2400 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum TIR\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: +0.00100 to -0.00100 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0020\/0.0000 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: -0.0600\/+0.0600 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: AN340\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 17002169\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557401755954,"sku":"17002169","price":77.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f3f71a3d3f0822572a54272ed24ff517_7cdae0dd-0f2e-4baa-87df-13f02c1511cc.jpg?v=1786387387","url":"https:\/\/voomisupply.com\/products\/seco-17002169-corner-radius-end-mill-1-4-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
