Ford. 11103940 Square End Mill 0.0394 in 4 Flute Carbide","description":"\u003ch3\u003eProduct Description\u003c\/h3\u003e\u003cp\u003eThe M.A. FORD. 11103940 is a solid carbide square end mill engineered for precision milling in demanding industrial and toolroom applications. With a 0.0394 inch (1.00 mm) mill diameter and a 0.1181 inch (3.00 mm) length of cut, this micro-diameter tool delivers tight tolerances and consistent performance at small scales. The four-flute spiral geometry supports efficient chip evacuation while maintaining a stable cutting edge. A 30-degree helix angle balances cutting forces across a range of workpiece materials. This tool is installed and operated by machinists and CNC toolroom technicians working on vertical machining centers, CNC mills, and manual milling equipment.\u003c\/p\u003e\u003cp\u003eThe 11103940 is suited for milling operations on materials spanning hardened metals, cast iron, stainless steels, non-ferrous alloys, plastics, and high-temperature alloys, consistent with its primary workpiece material codes H, K, M, N, P, and S. With a 1.5 inch overall length and a straight-cylindrical shank, it fits standard collet and end mill holder setups. The uncoated carbide substrate is appropriate for applications where coating interactions with workpiece chemistry are a concern or where regrinding is planned.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0394 inch (1.00 mm) mill diameter with tight diameter tolerance of +0.000 \/ -0.040 mm\u003c\/li\u003e\n\u003cli\u003eFour-flute spiral configuration for balanced chip load and surface finish\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle for stable cutting across varied material hardness levels\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute orientation — standard for conventional and climb milling\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and heat resistance at micro-diameter scale\u003c\/li\u003e\n\u003cli\u003eSeries 111, regular length type — suitable for general-purpose milling operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style cutting tool for use in standard collet chucks and end mill holders accepting a 3.00 mm straight-cylindrical shank, compatible with vertical machining centers and CNC milling equipment configured for micro-diameter tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC technician following the machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is in a safe state before inserting or removing the tool from the holder. Use a calibrated torque wrench on collet nuts to avoid over-tightening, which can deform the shank on micro-diameter tools. Confirm runout at the spindle before beginning a cutting pass, as even minor runout magnifies tool deflection and breakage risk at this diameter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.0394 inches (1.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.1181 inches (3.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: 30 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\u003eSeries\u003c\/strong\u003e: 111\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.040 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Codes\u003c\/strong\u003e: H, K, M, N, P, S\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: M.A. FORD.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 11103940\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51751006732594,"sku":"11103940","price":48.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2d2d4d7692845adba1af101eebb13d80.jpg?v=1788921104","url":"https:\/\/voomisupply.com\/products\/m-a-ford-11103940-square-end-mill-0-0394-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
