Built from M42 cobalt high-speed steel and finished with a TiCN coating, this tool handles tough ferrous and non-ferrous materials while maintaining edge integrity under heat and wear. The 1\/2 inch diameter cutter features four flutes with a right-hand spiral and right-hand cutting direction. With a 30-degree maximum helix angle and a short-length configuration, it delivers controlled chip evacuation during roughing passes. Licensed machinists and toolroom professionals specify cobalt end mills when carbide is cost-prohibitive or when working with interrupted cuts and variable stock conditions.\u003c\/p\u003e\u003cp\u003eThis end mill suits roughing applications in job shops, production milling, and toolroom environments. It is appropriate for use in CNC machining centers and manual knee mills where stock removal rate takes priority over surface finish. The 1 inch length of cut and 3 inch overall length position it for short-reach roughing slots and peripheral milling passes. The TiCN coating adds surface hardness and lubricity, extending tool life in moderate-speed cuts on steel, stainless, and alloy materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for heat and wear resistance beyond standard HSS\u003c\/li\u003e\n\u003cli\u003eTiCN coating increases surface hardness and reduces friction at the cutting edge\u003c\/li\u003e\n\u003cli\u003eFour-flute, right-hand spiral design promotes chip flow and cutting stability\u003c\/li\u003e\n\u003cli\u003e30-degree maximum helix angle suited for roughing passes on a range of materials\u003c\/li\u003e\n\u003cli\u003eShort-length configuration minimizes deflection in tight-reach applications\u003c\/li\u003e\n\u003cli\u003eSingle-end design; part of the REM445 series\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a roughing end mill for use in standard 1\/2 inch collets, end mill holders, and Weldon-style shanks on CNC machining centers and manual milling machines.

Ensure the spindle is fully stopped and locked before inserting or removing the end mill from its holder. Confirm holder runout is within tolerance before engaging the cut, as excessive runout accelerates edge wear on cobalt tooling. Follow the machine manufacturer's recommended speeds and feeds for cobalt end mills and the specific workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\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: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch (1.0000 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: 1\/2 inch (0.5000 inch)\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\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0005 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.003 to -0.000 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.062 to -0.000 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: REM445\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 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: 17015345\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559371079986,"sku":"17015345","price":90.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/add991b95d274334f47951d6255784ac.jpg?v=1786430508","url":"https:\/\/voomisupply.com\/products\/seco-17015345-roughing-end-mill-1-2-in-4-flute-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
