With a 0.1406-inch cutting diameter and a 4-flute configuration, this tool delivers smooth finishes and efficient chip evacuation in a compact stub-length form. The 40-degree helix angle promotes aggressive cutting action while reducing chatter. Manufactured from micrograin carbide, the 12184742 holds tight tolerances and maintains edge integrity across ferrous and non-ferrous materials. It is installed by machinists and toolroom technicians on CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for finishing passes and semi-finishing operations where tight tolerances and fine surface finishes are required. The stub length geometry provides added rigidity in tight setups and shallow-reach applications. With a 0.375-inch length of cut and 3\/16-inch shank diameter, it fits standard ER collet chucks and end mill holders commonly used in production and prototype machining environments. The uncoated micrograin carbide construction makes it appropriate for use with cutting fluids across a range of workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.1406-inch ball cutting diameter with mill diameter tolerance of +0.000 to -0.002 inches for precise profiling\u003c\/li\u003e\n\u003cli\u003e4-flute spiral configuration improves surface finish and feed rate capability\u003c\/li\u003e\n\u003cli\u003e40-degree right-hand helix angle reduces cutting forces and chatter\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for extended edge life and dimensional stability\u003c\/li\u003e\n\u003cli\u003eStub length design maximizes rigidity in short-reach and confined milling applications\u003c\/li\u003e\n\u003cli\u003eUncoated finish compatible with coolant use across ferrous and non-ferrous materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide ball end mill for CNC machining centers and manual mills accepting a 3\/16-inch shank diameter via standard ER collet chucks or end mill holders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Verify collet or holder bore matches the 3\/16-inch shank diameter and that runout is within acceptable limits before beginning a cut. Inspect the cutting edges for chips or damage before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1406 inches (9\/64 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 (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.375 inches (3\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\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\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\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.002 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\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\u003eChipbreaker\u003c\/strong\u003e: No\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: 12184742\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51747675275570,"sku":"12184742","price":30.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/83756285e6931ad10bf3280b9a88d33e.jpg?v=1788884375","url":"https:\/\/voomisupply.com\/products\/accupro-12184742-ball-end-mill-0-1406-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
