The tool carries a 0.750-inch mill diameter with a 0.375-inch nose radius and a 2.25-inch length of cut, giving it the reach needed for deep-cavity and contoured surface work. A TiCN PVD coating reduces heat buildup and extends tool life across a broad range of workpiece materials. The four-flute, right-hand spiral configuration with a 30-degree medium helix angle promotes efficient chip evacuation and stable cutting performance at elevated feeds.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for machining steel, stainless steel, cast iron, aluminum and non-ferrous metals, and high-temperature alloys, covering ISO material groups P, M, K, N, and S. It is a standard-length tool with a 0.750-inch Weldon flat shank and a 4.5-inch overall length, making it compatible with common milling chucks and collet holders used in CNC vertical and horizontal machining centers. Typical applications include die and mold work, aerospace component profiling, and general precision metalworking where a ball-nose geometry is required for 3D surface contouring.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt substrate with TiCN PVD coating for extended tool life in ferrous and high-temp alloy applications\u003c\/li\u003e\n\u003cli\u003eBall-nose geometry with 0.375-inch nose radius enables 3D contouring and profiling cuts\u003c\/li\u003e\n\u003cli\u003eFour right-hand spiral flutes at 30-degree medium helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank provides positive drive and resists pullout under heavy loads\u003c\/li\u003e\n\u003cli\u003eRated for both roughing and finishing material removal in a single tool\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eThe 17012965 is an SPB540-series cobalt ball end mill designed for use with standard Weldon flat milling tool holders accepting a 0.750-inch shank diameter.

Seat the Weldon flat shank securely in the tool holder and torque the set screw to the holder manufacturer's specification before engaging the spindle. Verify runout does not exceed the 0.001-inch TIR maximum before production cutting. Confirm cutting direction is set to right-hand before programming tool paths.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN (PVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SPB540\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0010 \/ -0.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.0600 \/ -0.0600 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 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: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 17012965\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51562111435058,"sku":"17012965","price":145.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c82b07dea2bb6ac9c6f4e7cafcb258ea_80a358f9-0f7f-41d9-9c75-687ad251ed95.jpg?v=1786471843","url":"https:\/\/voomisupply.com\/products\/seco-17012965-ball-end-mill-3-4-in-4-flute-cobalt-ticn-spb540","provider":"Voomi Supply","version":"1.0","type":"link"}
