Built from M42 cobalt high-speed steel, it features a 1\/2 inch cutting diameter, four spiral flutes, and a 3 inch length of cut, giving it the reach needed for slotting, peripheral milling, and aggressive roughing passes. The bright, uncoated finish suits a wide range of work materials where coating adhesion is not a requirement. Right-hand cutting and right-hand flute direction are standard. Licensed machinists and tool-room operators are the primary users of this style of end mill.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use on vertical machining centers, knee mills, and manual or CNC milling setups where high chip-load roughing is the objective. The Series REM445 designation places it in SECO's standard roughing geometry lineup. With a 5 inch overall length and a 1\/2 inch shank, it fits standard R8, ER, or set-screw-style collet holders without adapters. It is not center-cutting, so it requires a pre-drilled or pre-bored entry point for plunge operations. Coolant-through capability is not present on this model.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt high-speed steel construction for heat and wear resistance in demanding milling operations\u003c\/li\u003e\n\u003cli\u003e1\/2 inch cutting diameter with 3 inch length of cut for deep-reach roughing passes\u003c\/li\u003e\n\u003cli\u003eFour spiral flutes, right-hand cut, right-hand helix at 30 degrees maximum helix angle\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish — no coating compatibility concerns for general-purpose ferrous and non-ferrous stock\u003c\/li\u003e\n\u003cli\u003eSingle-end design, 5 inch overall length, 1\/2 inch shank diameter\u003c\/li\u003e\n\u003cli\u003eNot center-cutting — suited for peripheral and slot milling with pre-bored entry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style roughing end mill for use in standard 1\/2 inch collet or set-screw milling tool holders on manual and CNC vertical mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom professional. Power down and lock out the spindle drive before seating or removing the end mill from its holder. Ensure the shank is fully seated to the minimum insertion depth specified by the tool holder manufacturer. Shank diameter tolerance is -0.0001 to -0.0005 inches, so verify holder bore condition before use to avoid runout issues.\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 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\u003eLength of Cut\u003c\/strong\u003e: 3 inches (3.0000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 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\u003eCenter Cutting\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\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: 17010845\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559778287922,"sku":"17010845","price":131.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bc02fbdd14cb29a2ef9705c81c46f6d9_120b9ca6-00ec-4742-944e-52d322c8ecb4.jpg?v=1786440753","url":"https:\/\/voomisupply.com\/products\/seco-17010845-roughing-end-mill-1-2-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
