It features a 1\/4 inch diameter cutting edge with a 0.045 inch corner radius, a 3\/4 inch length of cut, and a 2-1\/2 inch overall length. The 2-flute, right-hand spiral geometry supports efficient chip evacuation and smooth cutting action. Micrograin carbide construction provides hardness and wear resistance suited for demanding cutting conditions. The bright\/uncoated finish makes this tool appropriate for a range of general-purpose milling tasks. Licensed machinists and CNC operators are the primary users of this tool in job shop and production environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in vertical and horizontal milling machines as well as CNC machining centers for contouring, slotting, and profiling operations where a controlled corner radius is required. The centercutting design allows plunge entry directly into workpiece material. The 1\/4 inch shank diameter fits standard collets and toolholders in that size range. A 40-degree helix angle promotes smooth cutting and helps reduce chatter during side milling passes. This tool is suited for use on ferrous and non-ferrous materials in both prototype and production runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.045 inch corner radius for consistent radiused edge profiles\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction for hardness and edge retention\u003c\/li\u003e\n  \u003cli\u003e2-flute geometry with right-hand spiral for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eCentercutting capability allows direct plunge entry\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle reduces chatter and improves surface finish\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for general-purpose milling applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 1\/4 inch collets and toolholders on CNC machining centers, vertical mills, and similar milling equipment requiring a corner radius end mill in this size range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC operators. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the tool from the toolholder. Seat the shank fully into the collet to the recommended engagement depth and torque the collet nut according to the toolholder manufacturer specifications. Verify runout with a dial indicator after tool installation before beginning a cutting operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.045 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\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Configuration\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide, Micrograin Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 to -0.002500 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\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.00150 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12181334\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51740614033714,"sku":"12181334","price":39.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d3da1d9c631f299bf9c5bda1b1a547fa.jpg?v=1788826217","url":"https:\/\/voomisupply.com\/products\/accupro-12181334-corner-radius-end-mill-1-4-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
