Built from M42 cobalt high-speed steel and coated with TiAlN, it handles elevated cutting temperatures and extends tool life in demanding applications. The 1\/2-inch diameter cutter features 4 right-hand spiral flutes with a 30-degree maximum helix angle and a 2-inch length of cut. The long-series geometry and chipbreaker-free profile make it well suited for roughing passes where stock removal rate matters more than surface finish. Licensed machinists and toolroom operators are the primary users of this end mill in both production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for roughing operations on ferrous and hard materials where cobalt tooling outperforms standard HSS. The 4-inch overall length and 1\/2-inch shank fit standard ER and straight-bore tool holders commonly found on vertical machining centers, knee mills, and CNC milling equipment. Right-hand cutting direction and right-hand flute orientation are standard for conventional and climb milling setups. It is sold as a single-end tool, meaning it is reground or replaced when worn rather than flipped. The long flute length supports deeper axial cuts in open-pocket and profile roughing passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt steel construction for heat and wear resistance in tough materials\u003c\/li\u003e\n\u003cli\u003eTiAlN coating extends tool life at higher cutting speeds and temperatures\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\u003e2-inch length of cut supports deeper axial engagement in roughing passes\u003c\/li\u003e\n\u003cli\u003eLong-series, single-end design with 1\/2-inch shank for broad tool-holder compatibility\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting and flute direction for standard milling spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use roughing end mill compatible with standard 1\/2-inch straight-bore and collet-style tool holders used on vertical and horizontal milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of end mills should be performed by qualified machinists following shop safety protocols. Power down and lock out the spindle before changing tooling. Ensure the shank is fully seated in the tool holder and that set screws or collet nuts are torqued per the tool-holder manufacturer's specification. Inspect the cutting edges and coating for chipping before each use; do not run a damaged tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 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: 2.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\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: TiAlN\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\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Helix Angle\u003c\/strong\u003e: 30 degrees\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\u003eChipbreaker\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: REM445\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: 17014827\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51558885785906,"sku":"17014827","price":115.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bc02fbdd14cb29a2ef9705c81c46f6d9_06576111-3441-44e3-8ae7-6b283cc6434e.jpg?v=1786421797","url":"https:\/\/voomisupply.com\/products\/seco-17014827-roughing-end-mill-1-2-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
