Built from solid carbide micrograin material, it delivers hardness and rigidity suited for high-speed cutting in ferrous and non-ferrous metals. The 4-flute, right-hand spiral configuration with a 40-degree helix angle promotes efficient chip evacuation and smooth surface finishes. An AlTiN coating adds thermal resistance and wear protection, extending tool life in demanding cutting environments. At 0.3438 inches in diameter with a 0.625-inch length of cut, this stub-length mill is well-suited for close-tolerance profiling, contouring, and slotting work.\u003c\/p\u003e\u003cp\u003eThis end mill is used in CNC machining centers and manual milling operations where ball-nose geometry is required for 3D contouring, radius profiling, and curved surface finishing. The stub-length design provides increased rigidity and reduced deflection, making it a reliable choice for precision work in tool and die, mold making, aerospace component machining, and general job shop applications. Machinists working with hardened steels, stainless, and high-temp alloys will benefit from the AlTiN coating under high cutting speeds.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide micrograin construction for hardness and dimensional stability\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for high-temperature wear resistance and extended tool life\u003c\/li\u003e\n\u003cli\u003e4-flute, right-hand spiral design with 40-degree helix for efficient chip flow\u003c\/li\u003e\n\u003cli\u003eBall-nose geometry for 3D contouring and radius profiling\u003c\/li\u003e\n\u003cli\u003eStub-length (short) configuration for improved rigidity and reduced deflection\u003c\/li\u003e\n\u003cli\u003eSingle-end design for straightforward toolholder mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 3\/8-inch collet chucks, end mill holders, and shrink-fit toolholders on CNC machining centers and manual knee mills capable of accepting right-hand cut tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety protocols. Ensure the machine spindle is fully stopped and powered down before changing tooling. Secure the shank fully within the toolholder to the recommended minimum engagement depth per toolholder manufacturer guidelines, and verify runout with a dial indicator before production cutting. Do not exceed the tool manufacturer's recommended cutting parameters for the workpiece material and coating type.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.3438 inches (11\/32 inches)\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: 0.375 inches (3\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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 Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\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 Type\u003c\/strong\u003e: Single End\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\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 pounds\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: 12184804\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728861462834,"sku":"12184804","price":62.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/448d3d92f4cf6e6c5c12300c7cf72813.jpg?v=1788697038","url":"https:\/\/voomisupply.com\/products\/accupro-12184804-ball-end-mill-0-3438in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
