Built from M42 cobalt high-speed steel, this tool offers elevated heat and wear resistance compared to standard HSS grades, making it well-suited for harder workpiece materials. The 6-flute geometry paired with a 30-degree right-hand spiral helix delivers efficient chip evacuation and a stable cutting action. The bright\/uncoated finish is production-ready out of the box. With a 3\/4 inch diameter and 4 inch length of cut, this end mill handles deep-pocket and long-reach slotting, profiling, and contouring operations across a broad range of materials.\u003c\/p\u003e\u003cp\u003eThis end mill is rated for use on steel, stainless steel, cast iron, aluminum and non-ferrous metals, and high-temperature alloys, covering ISO material groups P, M, K, N, and S. It belongs to SECO's SPC408 series and is sized for conventional milling machines, knee mills, CNC machining centers, and similar spindle-driven equipment in job shop or production environments. The single-end configuration and 3\/4 inch straight shank allow standard ER or end mill holder mounting. This tool is installed by machinists, toolroom technicians, and CNC operators in metalworking and manufacturing settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS material provides superior hot hardness and wear resistance versus standard M2 HSS\u003c\/li\u003e\n\u003cli\u003e6-flute design increases feed rate capability and improves surface finish on finishing passes\u003c\/li\u003e\n\u003cli\u003e30-degree right-hand helix promotes smooth cutting action and efficient chip flow\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish compatible with a wide range of cutting fluids and lubricants\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with matched 3\/4 inch shank and cutter diameter for direct holder fit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard end mill holders, collet chucks, or shrink-fit holders accepting a 3\/4 inch straight shank, as commonly found on manual knee mills and CNC vertical machining centers.

Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully in the holder to the recommended engagement depth and torque the retention screw or collet nut to the holder manufacturer's specification. Verify runout against the 0.0010 inch maximum TIR spec before beginning a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\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\u003eLength of Cut\u003c\/strong\u003e: 4 inches (4.0000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.25 inches (6-1\/4 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\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\u003eMaximum TIR\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\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\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: 17011794\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559774290226,"sku":"17011794","price":150.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/45e003f1f7c442eaf4a97369cd791473_403e4f8b-d161-4339-b18c-3fb6d4cda0fb.jpg?v=1786440631","url":"https:\/\/voomisupply.com\/products\/seco-17011794-square-end-mill-3-4-in-6-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
