Built from M42 cobalt high-speed steel, it handles tough ferrous and non-ferrous materials where standard HSS tooling falls short. The 1\/2 inch diameter cutter features 4 right-hand spiral flutes with a 30-degree maximum helix angle and a 1-1\/4 inch length of cut. The bright, uncoated finish makes it easy to inspect for wear. Overall length is 3-1\/4 inches with a 1\/2 inch straight shank. This tool is installed and used by machinists and tool-and-die professionals in manual and CNC milling operations.\u003c\/p\u003e\n\u003cp\u003eThis roughing end mill fits standard 1\/2 inch ER or side-lock milling chucks and collets. It is suited for roughing passes in ferrous alloys, stainless steels, and high-temperature alloys where the M42 cobalt grade provides added red hardness compared to M2 HSS. Regular-length geometry makes it appropriate for general shop use, vertical mill work, and CNC roughing cycles where a non-chipbreaker spiral flute profile is preferred. It is not center-cutting, so it requires a pre-drilled or pre-bored entry point before plunging.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt material grade for improved heat and wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003e4 right-hand spiral flutes with 30-degree maximum helix angle for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch mill diameter with matching 1\/2 inch shank for direct chuck compatibility\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no coating buildup on edge, easy wear inspection\u003c\/li\u003e\n  \u003cli\u003eSingle-end, regular-length geometry for general roughing passes\u003c\/li\u003e\n  \u003cli\u003eNot center-cutting — requires pre-bored entry; not designed for direct plunge cuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/2 inch shank roughing end mill compatible with ER collet chucks, Weldon side-lock holders, and similar 1\/2 inch bore milling tool holders used in manual knee mills and CNC machining centers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist or toolroom professional. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Torque the set screw or collet nut to the tool holder manufacturers specification. Confirm runout with a dial indicator before beginning a cut, as excessive runout accelerates flute wear and can cause chatter on roughing passes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 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\u003eLength of Cut\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.25 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\/Finish\u003c\/strong\u003e: Bright, Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: 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\u003eMaximum Helix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.003 to -0.000 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: +0.062 to -0.000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: REM710\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.16 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 17014087\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560793342258,"sku":"17014087","price":82.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/93f45d9f8df388e23e942ac1ad9f39bd.jpg?v=1786457636","url":"https:\/\/voomisupply.com\/products\/seco-17014087-roughing-end-mill-1-2-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
