It features a 0.5-inch cutting diameter with a 0.25-inch nose radius and a 1-inch length of cut. The TiCN PVD coating reduces friction and extends tool life across a range of workpiece materials. The 30-degree medium helix angle promotes smooth chip evacuation during right-hand cutting. This tool is intended for use by machinists and tool-and-die professionals working on CNC mills and manual milling machines where precise ball-nose profiling is required.\u003c\/p\u003e\u003cp\u003eThe SPB540 series ball end mill is suited for finishing passes on steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. Its short-length geometry and 0.5-inch Weldon flat shank provide rigid, secure tool holding in standard end mill holders. It is a single-end, spiral-flute design with no chipbreaker, no coolant-through provision, and no extended reach, making it best applied in close-clearance finishing setups where tool deflection must be minimized.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.5-inch ball nose diameter with 0.25-inch nose radius for accurate contour finishing\u003c\/li\u003e\n\u003cli\u003e4-flute cobalt construction with TiCN PVD coating for extended tool life on hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003e30-degree medium helix angle promotes efficient chip flow in right-hand cutting\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank provides positive drive and resists pull-out in high-feed applications\u003c\/li\u003e\n\u003cli\u003eShort-length geometry (3-inch OAL) maximizes rigidity during finishing cuts\u003c\/li\u003e\n\u003cli\u003eCompatible with steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 0.5-inch end mill holders and Weldon-style tool holders.

Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Secure the Weldon flat against the set screw in the tool holder to the shop standard torque specification for the holder size. Verify runout does not exceed the 0.001-inch TIR maximum before beginning the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SPB540\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 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: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 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\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Medium\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Short\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\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 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\u003eTIR Maximum\u003c\/strong\u003e: 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 17012957\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558312313138,"sku":"17012957","price":76.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5261e212fc9ef653adf727cf1e11636b.jpg?v=1786409186","url":"https:\/\/voomisupply.com\/products\/seco-17012957-ball-end-mill-0-5-in-4-flute-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
