The cutter measures 3\/16 inch (0.1875 inch) in diameter with a 1\/2 inch length of cut and a 2-3\/8 inch overall length. A TiCN (titanium carbonitride) PVD coating increases surface hardness and wear resistance, extending tool life in demanding applications. The 4-flute, right-hand spiral configuration with a 30-degree helix angle balances chip evacuation and surface finish. The 3\/8 inch Weldon Flat shank provides positive drive and reduces slippage in the spindle holder.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for roughing and finishing passes in steel, stainless steel, cast iron, aluminum and non-ferrous metals, and high-temperature alloys. The center-cutting geometry allows direct plunging into the workpiece, making it practical for profiling, contouring, slotting, and 3D surface work on CNC machining centers and manual mills equipped with a compatible collet or end mill holder. The standard length design fits most conventional setups without requiring extended-reach tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt substrate provides elevated heat and wear resistance compared to standard high-speed steel\u003c\/li\u003e\n\u003cli\u003eTiCN PVD coating (Coating Classification: PVD) increases surface hardness for extended tool life\u003c\/li\u003e\n\u003cli\u003e4-flute right-hand spiral with 30-degree medium helix balances chip flow and finish quality\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows direct plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eWeldon Flat shank (3\/8 inch) reduces rotational slippage in end mill holders\u003c\/li\u003e\n\u003cli\u003eRated for roughing and finishing in steel, stainless steel, cast iron, aluminum, non-ferrous, and high-temp alloys\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tool for CNC and manual milling machines accepting a 3\/8 inch Weldon Flat shank end mill holder; part of the SECO SPB540 series (Manufacturers Catalog Number: SPB540-0.188-F3-B.3-Z4).\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or toolroom technician using a torque-rated end mill holder or collet chuck compatible with the 3\/8 inch Weldon Flat shank. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Verify runout with a dial indicator after seating the tool; maximum TIR for this cutter is 0.0010 inch. Follow the machine manufacturer and applicable shop safety guidelines for speeds, feeds, and coolant strategy for the workpiece material being machined.\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: 3\/16 inch (0.1875 inch)\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\/2 inch (0.5000 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/8 inch (2.3750 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.0938 inch\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\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\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0010 \/ -0.0000 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.0600 \/ -0.0600 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum TIR\u003c\/strong\u003e: 0.0010 inch\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: 17016486\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558445023538,"sku":"17016486","price":69.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c82b07dea2bb6ac9c6f4e7cafcb258ea.jpg?v=1786412540","url":"https:\/\/voomisupply.com\/products\/seco-17016486-ball-end-mill-3-16-in-4-flute-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
