Built from M42 cobalt high-speed steel and finished with a TiAlN coating, it delivers heat resistance and edge retention under demanding cutting conditions. The tool measures 3\/8 inch in diameter with a 3\/4 inch length of cut and a 2-1\/2 inch overall length. Four right-hand spiral flutes and a 30-degree maximum helix angle work together to clear chips efficiently while maintaining surface contact during roughing passes. Licensed machinists and tool-and-die professionals are the primary users of this type of end mill.\u003c\/p\u003e\u003cp\u003eThis roughing end mill is suited for use on vertical and horizontal milling machines and compatible machining centers where interrupted, high-feed roughing cuts are required. It performs well in ferrous alloys and stainless steels where cobalt tooling is preferred for its elevated red hardness. The short flute length and rigid shank design minimize deflection in setups with tight reach requirements. It is not center-cutting, so it requires a pre-drilled entry point or ramping entry when plunging into solid material.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for elevated heat and wear resistance compared to standard HSS\u003c\/li\u003e\n\u003cli\u003eTiAlN coating extends tool life in high-temperature cutting environments\u003c\/li\u003e\n\u003cli\u003e4 right-hand spiral flutes with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003e3\/8 inch shank diameter matches mill diameter for straightforward collet or end mill holder setup\u003c\/li\u003e\n\u003cli\u003eShort length type reduces overhang and improves rigidity during roughing passes\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction; non-center-cutting design requires ramp or pre-drilled entry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit roughing end mill for use with standard 3\/8 inch collets, end mill holders, or shrink-fit tooling systems on manual and CNC milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Power down and lock out the spindle before loading or removing tooling. Ensure the shank is clean and free of chips before seating in the holder, and verify runout with a dial indicator after clamping. Do not exceed the rated depth-of-cut parameters recommended for the workpiece material and machine rigidity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inch decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/4 inch (0.7500 inch decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inch decimal)\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\u003eMaximum Helix 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\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: Short\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: REM445\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\u003eWeight\u003c\/strong\u003e: 0.3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 17014821\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558286721330,"sku":"17014821","price":75.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bc02fbdd14cb29a2ef9705c81c46f6d9_4108eaf2-d605-4936-b3b1-ca061710c214.jpg?v=1786408551","url":"https:\/\/voomisupply.com\/products\/seco-17014821-roughing-end-mill-3-8-inch-cobalt-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
