Built from M42 cobalt high-speed steel with a bright, uncoated finish, it delivers durability and edge retention where standard HSS tooling wears prematurely. The cutter measures 0.500 inches in diameter with a 2.000-inch length of cut and a 4.000-inch overall length. Four right-hand spiral flutes with a 30-degree maximum helix angle break chips aggressively during roughing passes. This tool is installed and operated by machinists and tool-and-die professionals on CNC mills, manual knee mills, and bridgeports.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for roughing passes in ferrous alloys, stainless steel, and other tough materials where cobalt tooling provides a thermal and wear advantage over standard M2 HSS. The 1\/2-inch shank fits standard ER, Weldon, and shrink-fit toolholders common in job shop and production machining environments. It is a single-end, non-center-cutting tool, meaning it is not designed for direct plunge entry. Typical use involves side milling, slotting with a ramped entry, or profiling where maximum material removal per pass is the priority before a finishing end mill is brought in.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt HSS construction for improved heat and wear resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003eFour right-hand spiral flutes with chipbreaker-style roughing geometry for aggressive stock removal\u003c\/li\u003e\n\u003cli\u003e30-degree maximum helix angle promotes chip evacuation in deep cuts\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish maintains sharp edge geometry on the cutting lips\u003c\/li\u003e\n\u003cli\u003e1\/2-inch shank diameter matches mill diameter for direct toolholder compatibility\u003c\/li\u003e\n\u003cli\u003eRegular-length series REM710 geometry balances reach and rigidity in typical roughing setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style roughing end mill replacement for 1\/2-inch toolholders used in standard CNC and manual milling applications requiring a single-end, 4-flute cobalt rougher.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists. Power down and lock out the spindle drive before seating or removing the end mill from its toolholder. Verify shank runout with a dial indicator after clamping, as shank diameter tolerance on this tool is -0.0001 to -0.0005 inches and toolholder fit directly affects surface finish and tool life. This is a non-center-cutting tool — do not plunge directly into solid material; use a ramped or helical entry path.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.000 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 HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright, Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle (Maximum)\u003c\/strong\u003e: 30 degrees\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\u003eSingle or Double End\u003c\/strong\u003e: Single End\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: REM710\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: 0.18 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: 17014088\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557671633202,"sku":"17014088","price":108.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a98fd236090fa45a0e54e321483dac03_f5f289f3-d6ae-40ef-923d-f0a3f33cf0be.jpg?v=1786392508","url":"https:\/\/voomisupply.com\/products\/seco-17014088-roughing-end-mill-1-2-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
