Built from M42 cobalt high-speed steel, it delivers heat resistance and edge toughness in demanding cuts. The 4-flute spiral configuration with a 30-degree maximum helix angle produces efficient chip evacuation while maintaining surface control. The bright, uncoated finish suits a wide range of ferrous and non-ferrous materials. With a 0.2500-inch mill diameter and a 1.2500-inch length of cut, this tool is sized for precise slotting and profiling passes in standard vertical and horizontal milling setups.\u003c\/p\u003e\u003cp\u003eThis roughing end mill is suited for production and job shop environments where machinists need reliable stock removal in steel, stainless, and similar alloys. The 3\/8-inch shank diameter fits standard R8, collet chuck, and end mill holder tooling common in manual and CNC milling machines. Right-hand cutting and right-hand flute direction make it compatible with conventional spindle rotation. The regular-length designation keeps it rigid in setups where reach is not a limiting factor, reducing vibration and deflection during heavy cuts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt high-speed steel construction for elevated heat and wear resistance\u003c\/li\u003e\n\u003cli\u003e4-flute spiral design with 30-degree maximum helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish compatible with a broad range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eSingle-end, right-hand cut with right-hand flute direction for standard spindle use\u003c\/li\u003e\n\u003cli\u003eRegular-length body provides rigidity and reduces deflection in heavy roughing passes\u003c\/li\u003e\n\u003cli\u003eSeries REM710 designation for straightforward replacement and reorder identification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-shank roughing end mill with a 3\/8-inch shank diameter, compatible with collet chucks, R8 holders, and end mill holders sized for 3\/8-inch tooling on manual and CNC milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists following standard toolroom procedures. Ensure the spindle is fully powered down and locked before inserting or removing the end mill from the holder. Verify holder runout with a dial indicator before initiating cuts, as excessive runout accelerates edge wear on cobalt tooling. Do not use this tool for center-drilling or plunge entry, as it is not centercutting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Fractional)\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (Decimal)\u003c\/strong\u003e: 0.2500 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\u003eLength of Cut\u003c\/strong\u003e: 1.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter (Fractional)\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter (Decimal)\u003c\/strong\u003e: 0.3750 inches\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\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\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\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\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 17014066\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560178712882,"sku":"17014066","price":76.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a98fd236090fa45a0e54e321483dac03_282387b5-f1b1-4b06-9717-90f1a5f1a686.jpg?v=1786448384","url":"https:\/\/voomisupply.com\/products\/seco-17014066-roughing-end-mill-1-4-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
