With a 0.4375 inch (7\/16 inch) cutting diameter and a 3 inch length of cut, this tool handles deep-cavity profiling, contouring, and 3D surfacing work where standard-length end mills cannot reach. The 6 inch overall length places it in the extra-long category, giving machinists the reach needed for deep-pocket applications without sacrificing rigidity. A 40-degree helix angle promotes smooth chip evacuation and reduces cutting forces during aggressive passes. The micrograin carbide construction delivers consistent edge life across a range of workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits CNC machining centers and manual mills running ferrous and non-ferrous materials in job shop, tool-and-die, aerospace, and mold-making environments. The extra-long reach makes it particularly well suited for deep rib milling, core and cavity work in injection molds, and contoured surface finishing where cutter length is a limiting factor. Single-end construction means the tool is replaced rather than flipped when one end wears.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.4375 inch (7\/16 inch) ball nose cutting diameter for profiling and 3D contouring\u003c\/li\u003e\n  \u003cli\u003e3 inch length of cut provides deep-pocket reach in a single setup\u003c\/li\u003e\n  \u003cli\u003e6 inch overall length — extra-long designation for deep-cavity applications\u003c\/li\u003e\n  \u003cli\u003e40-degree right-hand helix promotes efficient chip evacuation and smooth cut feel\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for extended edge retention and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eUncoated finish allows direct use on a wide range of materials without coating compatibility concerns\u003c\/li\u003e\n  \u003cli\u003e2-flute, single-end design with right-hand cutting direction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for CNC machining centers and manual milling machines accepting a 7\/16 inch straight shank, with a shank diameter tolerance of -0.0001 to -0.0004 inches for consistent chuck and collet fit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures. Power down and lock out the spindle before inserting or removing the tool from the collet or end mill holder. Ensure the shank is fully seated to the minimum insertion depth recommended for the holder type to prevent pullout under load. Verify runout with a dial indicator before committing to a production pass, particularly given the extra-long reach, which amplifies deflection if overhang is excessive.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.4375 inches (7\/16 inch)\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7\/16 inch (0.4375 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\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\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\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting 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\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\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\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Extra Long\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: 12184256\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738717684018,"sku":"12184256","price":149.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/be72eb685b72af1042d27b177d68f93e_4754c277-b4da-4291-89fe-b6ee3d6ecdb0.jpg?v=1788803330","url":"https:\/\/voomisupply.com\/products\/accupro-12184256-ball-end-mill-0-4375-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
