Built from M42 cobalt high-speed steel, it delivers strong heat and wear resistance in demanding cutting conditions. The 0.5 inch diameter, 4-flute spiral configuration with a 30-degree maximum helix angle provides efficient chip evacuation while maintaining a stable cut. The bright\/uncoated finish suits a wide range of ferrous and non-ferrous materials. With a 1 inch length of cut and 3 inch overall length, this short-series end mill fits standard milling chucks and collets used in production and job shop environments. Licensed machinists and toolroom technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis roughing end mill is suited for face milling, slotting, and peripheral milling applications in short-reach setups. The right-hand cutting and right-hand flute direction make it compatible with conventional CNC machining centers and manual knee mills. The non-center-cutting geometry means it is intended for side milling and ramping entries rather than plunge cuts. Its short-series length type provides added rigidity when machining steel, stainless, and other tough alloys at higher feed rates. The Series REM445 designation identifies it within a family of roughing end mills intended for high-material-removal-rate work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS construction for elevated heat resistance and extended tool life in tough alloys\u003c\/li\u003e\n  \u003cli\u003e4-flute spiral design with 30-degree maximum helix angle for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute direction for standard CNC and manual milling spindles\u003c\/li\u003e\n  \u003cli\u003eShort-series length provides increased rigidity and reduced deflection\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish compatible with a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eNon-center-cutting geometry optimized for side milling and ramping entries\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style roughing end mill for use in standard 1\/2 inch milling chucks, collet holders, and end mill adapters on CNC machining centers and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolroom technicians. Ensure the spindle is fully stopped and locked out before changing tooling. Seat the shank fully in a clean, burr-free collet or chuck to the depth recommended by the toolholder manufacturer. Verify runout with a dial indicator before commencing cuts, as excessive runout will reduce tool life and surface finish quality.\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\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 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\u003eEnd Mill Material\u003c\/strong\u003e: Cobalt (M42 HSS)\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: Short\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\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: 0.09 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: 17010839\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557562319154,"sku":"17010839","price":82.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/553762866a7b17bd61c446847fa9ae18.jpg?v=1786390966","url":"https:\/\/voomisupply.com\/products\/seco-17010839-roughing-end-mill-1-2-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
