Built from M42 cobalt high-speed steel and coated with TiAlN for extended tool life and heat resistance, this end mill measures 3\/16 inch in diameter with a 3\/8 inch shank diameter. It features 4 spiral flutes in a right-hand cutting and flute direction, a 30-degree maximum helix angle, and a 1\/2 inch length of cut. The 2-3\/8 inch overall length suits a range of milling setups. Center-cutting capability allows for direct plunge entry. Licensed machinists and CNC operators working in job shops, tool rooms, and production environments are the primary users.\u003c\/p\u003e\u003cp\u003eThis roughing end mill is suited for milling ferrous metals and high-temperature alloys where standard HSS tooling falls short. The TiAlN coating provides thermal stability, making it effective in dry or minimal-lubrication cutting conditions. The chipbreaker-free, spiral flute geometry moves chips efficiently during roughing passes. It fits standard ER and side-lock toolholders that accept a 3\/8 inch shank. Typical applications include slotting, profiling, and step milling on CNC machining centers and manual knee mills.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for hardness and wear resistance beyond standard M2 HSS\u003c\/li\u003e\n\u003cli\u003eTiAlN coating for high-temperature performance and extended tool life\u003c\/li\u003e\n\u003cli\u003e4 spiral flutes with right-hand cut for efficient chip evacuation during roughing\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge milling without pre-drilling\u003c\/li\u003e\n\u003cli\u003e30-degree maximum helix angle balances chip flow and cutting stability\u003c\/li\u003e\n\u003cli\u003e3\/8 inch shank diameter fits standard toolholders widely used in CNC and manual setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement-grade roughing end mill for use in standard 3\/8 inch shank toolholders on CNC machining centers and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or CNC setup technicians. Ensure the machine spindle is fully powered down and locked before changing tooling. Confirm the toolholder collet or set-screw bore matches the 3\/8 inch shank diameter and that runout is within acceptable tolerance before beginning a cutting pass. Follow shop safety practices and applicable machine guarding requirements when operating milling equipment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Fractional)\u003c\/strong\u003e: 3\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Decimal)\u003c\/strong\u003e: 0.1875 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)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\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\u003eMaximum Helix Angle\u003c\/strong\u003e: 30 degrees\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\u003eSeries\u003c\/strong\u003e: REC448\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.9 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: 17007757\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558126485810,"sku":"17007757","price":81.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2ef223aa93df79ee433dab4e3e962c83.jpg?v=1786404143","url":"https:\/\/voomisupply.com\/products\/seco-17007757-roughing-end-mill-3-16-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
