Built from M42 cobalt high-speed steel, it delivers toughness and heat resistance suited to demanding cutting applications. The cutter measures 1.25 inches in diameter with a 3-inch length of cut and a 5.5-inch overall length, fitting a 1.25-inch shank. The bright, uncoated finish is standard for this grade. A 30-degree helix angle and right-hand spiral flutes promote smooth chip evacuation and stable cutting across a range of workpiece materials. Licensed machinists and toolroom technicians are the primary installers and users of this tool.\u003c\/p\u003e\n\u003cp\u003eThe 17011875 is rated for use on steel, stainless steel, cast iron, aluminum and non-ferrous metals, and high-temperature alloys, covering ISO material codes P, M, K, N, and S. It is center-cutting, allowing plunge entry as well as peripheral milling. The short-length classification and rigid 6-flute geometry make it well suited to finishing passes and semi-finish work in production and toolroom environments where runout control is critical. It carries a maximum TIR of 0.001 inch, supporting tight-tolerance work on CNC machining centers and manual knee mills.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for elevated heat resistance and edge retention in tough alloys\u003c\/li\u003e\n  \u003cli\u003e6-flute geometry supports higher feed rates and improved surface finish on finishing passes\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003e30-degree right-hand spiral flute promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish compatible with oil-based and soluble cutting fluids\u003c\/li\u003e\n  \u003cli\u003eMaximum TIR of 0.001 inch for precise, repeatable cuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003ePart of the SECO SPC408 series.

Secure the shank fully in a collet, end mill holder, or Weldon-style holder before operation, and verify runout with a dial indicator before cutting. Always power down the machine spindle and confirm it has come to a complete stop before changing or inspecting the cutter. Do not exceed the manufacturer-recommended cutting parameters for the workpiece material and do not use the tool if chipping or edge wear is visible.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\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 (M42)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting 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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0030 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.0620 to 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum TIR\u003c\/strong\u003e: 0.001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SPC408\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 17011875\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559834255666,"sku":"17011875","price":242.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/45e003f1f7c442eaf4a97369cd791473_5210e78d-b3eb-4523-af77-ed7cbc424d71.jpg?v=1786442313","url":"https:\/\/voomisupply.com\/products\/seco-17011875-square-end-mill-1-1-4-in-6-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
