It features a 1-inch mill diameter, a 2-inch length of cut, and a 4-flute spiral flute configuration with a 30-degree medium helix angle. The tool carries a TiCN (PVD) coating that improves wear resistance and extends tool life in demanding cutting environments. The 1-inch Weldon Flat shank provides a secure, slip-resistant connection in standard end mill holders. Overall length is 4.5 inches and the tool weighs approximately 0.3 pounds.\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 codes P, M, K, N, and S. The short-length, center-cutting design makes it appropriate for both plunge entry and side milling operations in general machining and tool room environments. Right-hand cutting and right-hand flute direction are standard. No chipbreaker, no extended reach, and no coolant-through provision, making this a straightforward, solid-body tool for conventional CNC machining centers and knee mills.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt substrate with TiCN PVD coating for improved hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003e4 spiral flutes with 30-degree medium helix angle for balanced chip evacuation and surface finish\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eWeldon Flat shank provides positive drive and reduces pullout risk in holders\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard CNC and manual mill spindles\u003c\/li\u003e\n\u003cli\u003eSuitable for roughing and finishing in a single tool across multiple ISO material groups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 1-inch end mill holders or Weldon-style collet chucks compatible with a 1-inch shank diameter.

Confirm the holder is clean and free of chips before seating the Weldon Flat shank, and torque the set screw to the holder manufacturer specification. Verify TIR does not exceed 0.0010 inches after installation before beginning a cut. Always stop the spindle and follow lockout procedures before changing or adjusting tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2 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: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Radius\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\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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, Aluminum and Non-Ferrous, High-Temp Alloy\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: 0.0010 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SPB540\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: 17016494\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558998966578,"sku":"17016494","price":199.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c82b07dea2bb6ac9c6f4e7cafcb258ea_abaed30f-cf2c-4046-8547-c2a08a78b1fd.jpg?v=1786425366","url":"https:\/\/voomisupply.com\/products\/seco-17016494-ball-end-mill-1in-4-flute-cobalt-ticn-spb540","provider":"Voomi Supply","version":"1.0","type":"link"}
