With a 15\/64 inch (0.2344 inch) cutting diameter and a 3\/4 inch length of cut, this tool delivers consistent material removal in tight tolerances. The 3-flute, spiral geometry with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Built from micrograin solid carbide, it holds a sharp edge longer than high-speed steel alternatives. The centercutting design allows direct plunge entry without a pre-drilled pilot hole, making it suitable for slotting, profiling, and pocket milling.\u003c\/p\u003e\u003cp\u003eThis end mill fits standard 1\/4 inch collets and tool holders, making it a practical choice for CNC machining centers and manual knee mills used in job shops, maintenance environments, and precision fabrication. The right-hand cut and right-hand flute configuration matches the most common spindle setups. Its regular length classification and 2-1\/2 inch overall length keep deflection low during close-tolerance work. Machinists working on aluminum, steel, stainless, brass, and similar materials will find this uncoated carbide tool well-suited to general-purpose applications where a coating is not required or where regrinding is planned.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e15\/64 inch (0.2344 inch) cutting diameter with a mill diameter tolerance of +0.000 \/ -0.002 inches for consistent fitment\u003c\/li\u003e\n\u003cli\u003e3-flute spiral geometry with a 40-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without a pilot hole\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for extended tool life and edge retention\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute — compatible with standard CNC and manual spindle setups\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for general-purpose use and regrinding\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 1\/4 inch collets and tool holders on CNC machining centers and manual milling machines where a regular-length, 3-flute square end mill is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom professional. Power down and lock out the spindle before changing tooling. Seat the shank fully into the collet to the manufacturer-recommended engagement depth and torque the collet nut according to the tool holder specification. Verify runout with a dial indicator before beginning cuts; excessive runout accelerates edge wear and reduces dimensional accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 15\/64 inch (0.2344 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 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: 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\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12181944\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51746460074290,"sku":"12181944","price":32.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5c56d4557151c3efce0cfef2461876b9.jpg?v=1788870473","url":"https:\/\/voomisupply.com\/products\/accupro-12181944-square-end-mill-15-64-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
