Built from micrograin solid carbide, this single-end tool features a 0.3906-inch diameter cutting edge and a TiCN (titanium carbonitride) coating that extends tool life by reducing friction and improving wear resistance at elevated temperatures. With a 2-flute configuration and a 40-degree helix angle, it is suited for applications requiring sharp chip evacuation and clean surface finishes in ferrous and non-ferrous materials. Machinists and toolroom operators rely on this geometry for contouring, slotting, and profiling cuts.\u003c\/p\u003e\n\u003cp\u003eThis stub-length ball end mill is used in CNC machining centers and manual mills across job shops, tool-and-die operations, and production machining environments. The 0.625-inch length of cut and 7\/16-inch shank diameter make it appropriate for shallow-to-medium-depth profiling passes where rigidity is a priority. The right-hand cutting and right-hand spiral flute direction suit standard spindle configurations. Its stub length reduces deflection, which is especially valuable in tight-tolerance finishing work on molds, dies, and contoured part features.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for hardness and thermal stability\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and extends tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n  \u003cli\u003e2-flute ball end geometry supports contouring, profiling, and slotting\u003c\/li\u003e\n  \u003cli\u003eStub-length design minimizes deflection during finish-pass operations\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with right-hand cut and right-hand flute spiral\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and manual mills with standard 7\/16-inch collet or toolholder systems accepting right-hand cutting solid carbide end mills.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the shank fully in a clean, properly sized collet or end mill holder and torque to the toolholder manufacturer specification. Verify runout with a dial indicator before beginning a production run, as excessive runout accelerates coating wear and reduces tool life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.3906 inches (25\/64 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.625 inches (5\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4375 inches (7\/16 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\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\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\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\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: 12184164\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728709812530,"sku":"12184164","price":101.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/be72eb685b72af1042d27b177d68f93e.jpg?v=1788695334","url":"https:\/\/voomisupply.com\/products\/accupro-12184164-ball-end-mill-0-3906-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
