Built from M42 cobalt high-speed steel and coated with TiCN, it delivers improved wear resistance and heat tolerance compared to standard HSS tooling. The cutter measures 1.5 inches in diameter with a 1.625-inch length of cut and a 1.25-inch shank diameter, fitting standard collet chucks and end mill holders. The spiral flute geometry with a 30-degree helix promotes chip evacuation and smooth cutting action. It is centercutting, allowing plunge entry into the workpiece. Machinists and tool and die professionals rely on this geometry for roughing and semi-finishing operations on demanding materials.\u003c\/p\u003e\n\u003cp\u003eThe 17016386 is rated for primary workpiece materials including steel, stainless steel, cast iron, and high-temperature alloys, covering ISO material groups P, M, K, and S. The stub-length classification keeps overhang minimal, improving rigidity on knee mills, machining centers, and manual mills. The 4.125-inch overall length suits most standard toolholders. The SP205 series designation places this tool within SECO's cobalt end mill line, intended for shops running conventional or CNC milling equipment where carbide is cost-prohibitive or tool breakage is a concern in interrupted cuts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt construction for elevated red-hardness and toughness in difficult alloys\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and extends tool life on steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge milling without a pre-drilled entry hole\u003c\/li\u003e\n  \u003cli\u003e30-degree helix spiral flute promotes efficient chip evacuation and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute configuration for standard spindle direction\u003c\/li\u003e\n  \u003cli\u003eStub-length profile minimizes deflection and improves rigidity at full diameter engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard end mill holders, collet chucks, and Weldon-style holders accepting a 1.25-inch shank diameter.

Verify TIR at the cutting edge does not exceed 0.001 inches before engaging the workpiece. Ensure the machine spindle is fully stopped and power is locked out before changing tooling. Do not exceed the rated depth of cut for the material group being machined, and confirm holder set screw torque meets the toolholder manufacturer specification.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.625 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\u003eOverall Length\u003c\/strong\u003e: 4.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SP205\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\u003eMaximum TIR\u003c\/strong\u003e: 0.001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, High-Temp Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 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: 17016386\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557726159154,"sku":"17016386","price":258.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/686dc3695ff3f36c37307c60b1cee92c_75b751b6-6f71-4790-8b07-9dac29c25323.jpg?v=1786393664","url":"https:\/\/voomisupply.com\/products\/seco-17016386-square-end-mill-1-1-2-in-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
