Built from fine-grain solid carbide and coated with AlTiN via PVD process, this tool delivers reliable cutting performance on steel, stainless steel, cast iron, high-temp alloys, and hardened materials. The 0.5-inch diameter with a 2-flute, right-hand spiral configuration and 30-degree medium helix produces stable chip evacuation and consistent surface finishes. Center-cutting geometry enables direct plunging and ramping operations without a pre-drilled entry point. Licensed machinists and CNC operators in job shops and production environments rely on this stub-length design for rigidity in tight-tolerance applications.\u003c\/p\u003e\u003cp\u003eThe 4173915 is suited for both roughing and finishing operations across a broad range of ferrous workpiece materials. Its short stub-length design minimizes deflection, making it appropriate for applications where tool overhang must be kept to a minimum. The straight-cylindrical shank seats directly into standard ER collets or end mill holders with a 0.5-inch bore. The single-end configuration and fine-grain carbide substrate are optimized for production milling where dimensional consistency is critical. This tool is not recommended for reconditioning after wear.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN coating applied by PVD process for heat resistance and extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003eFine-grain solid carbide substrate provides edge stability and wear resistance\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design supports plunging and ramping operations\u003c\/li\u003e\n\u003cli\u003e30-degree medium helix with right-hand flute direction for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eStub-length construction reduces deflection and improves cutting stability\u003c\/li\u003e\n\u003cli\u003eCompatible with workpiece material codes P, M, K, S, and H covering steel through hardened alloys\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide ball end mill for use in standard 0.5-inch end mill holders, ER collet chucks, and hydraulic or shrink-fit toolholders accepting a straight-cylindrical shank.

Verify the holder bore tolerance matches the shank diameter tolerance of +0.0000\/-0.0043 inches before seating. Ensure the machine spindle is fully stopped and de-energized before changing tooling. This tool is not recommended for reconditioning; replace at end of service life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 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: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Fine-Grain Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN (PVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, High-Temp Alloy, Hardened Materials\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0020 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0043 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: GOmill UEBD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.02 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: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4173915\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51727262875954,"sku":"4173915","price":143.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0b84748519207f0b9654a8450a4ea5bb.jpg?v=1788675623","url":"https:\/\/voomisupply.com\/products\/kennametal-4173915-ball-end-mill-0-5-in-2-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
