Manufactured from M42 cobalt high-speed steel, it delivers heat and wear resistance beyond standard M2 HSS tooling. The cutter measures 0.5 inches in diameter with a 4-inch length of cut, a 0.5-inch shank diameter, and a 6-inch overall length. Four spiral flutes with a 30-degree helix angle provide efficient chip evacuation and a smooth cutting action. The uncoated bright finish is standard for this series. Right-hand cut and right-hand flute geometry follow conventional milling orientation. Licensed machinists and CNC operators install this tool in vertical and horizontal milling machines.\u003c\/p\u003e\u003cp\u003eThe 17011742 belongs to the SECO SPC408 series, a regular-length line designed for versatile material removal across a broad range of workpiece types. Rated primary workpiece materials include steel, stainless steel, cast iron, aluminum and non-ferrous alloys, and high-temperature alloys. The centercutting design allows plunge entry directly into the workpiece, making it suitable for slotting, profiling, and pocketing operations. No coolant-through capability is present, so external coolant application or air blast is recommended for chip management in deep cuts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for elevated heat resistance versus standard HSS\u003c\/li\u003e\n\u003cli\u003e4-inch length of cut supports deep slotting and profiling passes\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes smooth chip flow and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry enables direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute — standard orientation for conventional milling setups\u003c\/li\u003e\n\u003cli\u003eUncoated bright finish; compatible with a wide range of cutting fluids\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tooling option for standard 0.5-inch collet or end mill holders in vertical mills, CNC machining centers, and manual Bridgeport-style machines.

Ensure the spindle is fully stopped and the machine is in a locked or e-stopped state before inserting or removing the end mill. Seat the shank fully into the collet or end mill holder and torque the retention mechanism to the tool-holder manufacturer specification. Verify runout against the stated TIR maximum of 0.0010 inches before beginning the cut. Inspect the collet bore for wear or contamination that could affect concentricity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 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\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42 HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eFlute Type\u003c\/strong\u003e: Spiral\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\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\/-0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.0620\/0.0000 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: SPC408\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 17011742\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51562274881842,"sku":"17011742","price":120.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/45e003f1f7c442eaf4a97369cd791473_89194f37-2d6f-4a7f-adf8-a2e250da3a30.jpg?v=1786474497","url":"https:\/\/voomisupply.com\/products\/seco-17011742-square-end-mill-1-2-in-4-flute-cobalt-spc408","provider":"Voomi Supply","version":"1.0","type":"link"}
