Built from micrograin solid carbide, it delivers the rigidity and wear resistance required for aggressive cutting in ferrous and non-ferrous materials. The 10 mm (0.3937 inches) cutting diameter pairs with a 40-degree helix angle and spiral flute geometry to promote efficient chip evacuation and reduce cutting forces. An AlTiN coating extends tool life at elevated temperatures, making it well suited for dry or semi-dry high-speed machining. This tool is installed and operated by machinists and CNC programmers working in job shops, aerospace, mold-and-die, and general manufacturing environments.\u003c\/p\u003e\n\u003cp\u003eThe 12177264 is used in CNC machining centers and manual mills for profiling, contouring, slotting, and 3D surface work. The extended reach configuration, with a reach length of 3.268 inches and a neck diameter of 0.378 inches, allows access to deeper features and pocketed geometries where standard-reach tools cannot reach. With a 2-flute design, this end mill is appropriate for moderate to high material removal in medium-hardness steels, stainless, aluminum, and similar alloys. The right-hand cut and right-hand flute direction are standard for conventional CNC spindle setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for superior hardness and edge retention\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating provides high-temperature oxidation resistance for extended tool life in dry cutting\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle with spiral flutes for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eExtended reach design with 3.268-inch reach length for deep-feature access\u003c\/li\u003e\n  \u003cli\u003eSingle-end, 2-flute configuration suited for profiling and 3D contouring\u003c\/li\u003e\n  \u003cli\u003eMill diameter tolerance of +0.0000 to -0.0025 inches for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard shank ball end mill compatible with CNC machining centers and manual mills accepting a 10 mm (0.3937-inch) round shank via collet, end mill holder, or shrink-fit tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following the tool holder manufacturer torque and runout specifications. Ensure the spindle is fully stopped and the machine is in a safe state before loading or removing the tool. Verify shank seating depth and minimize tool overhang beyond the specified reach length to reduce deflection and chatter. Consult the machining center manufacturer guidelines and applicable shop safety procedures before operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.3937 inches (10 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.7087 inches (18 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.7244 inches (120 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3937 inches (10 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.378 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 3.268 inches\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\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\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  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0025 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\u003eWeight\u003c\/strong\u003e: 0.393 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: 12177264\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51734269362482,"sku":"12177264","price":207.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/00f74cba8cf337601c3e2300d5162e08.jpg?v=1788761891","url":"https:\/\/voomisupply.com\/products\/accupro-12177264-ball-end-mill-0-3937in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
