Built from M42 cobalt high-speed steel and coated with TiCN for enhanced wear resistance and heat tolerance, this tool handles tough ferrous and non-ferrous materials in production and job-shop environments. The 3\/4 inch cutting diameter pairs with a 3 inch length of cut and a 5.25 inch overall length, making it well suited for deep-pocket roughing passes. Four right-hand spiral flutes with a maximum helix angle of 30 degrees promote efficient chip evacuation during heavy-feed operations. Machinists and tool-and-die professionals are the primary users of this end mill.\u003c\/p\u003e\u003cp\u003eThis roughing end mill is intended for use in vertical machining centers, knee mills, and manual milling machines where rapid stock removal is required. The TiCN coating extends tool life when cutting alloy steels, tool steels, and similar hard materials. The regular-length geometry and 3\/4 inch straight shank suit standard ER or side-lock toolholders commonly found in machine shops. It is a single-end design, meaning the tool is not reversible, and it is not center-cutting, so it cannot be plunged directly into solid material without a pre-drilled entry point.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt construction for improved red hardness and wear resistance over standard M2 HSS\u003c\/li\u003e\n\u003cli\u003eTiCN coating reduces friction and extends tool life in alloy and tool steel applications\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\u003e3 inch length of cut supports deep-pocket and full-depth roughing passes\u003c\/li\u003e\n\u003cli\u003eNon-center-cutting design optimized for peripheral and slot roughing, not direct plunge entry\u003c\/li\u003e\n\u003cli\u003eSeries REM445 geometry engineered for high-feed roughing with controlled chip load per flute\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 3\/4 inch toolholders compatible with SECO REM445 series geometry.

Secure the 3\/4 inch shank fully within the toolholder to the manufacturer-recommended engagement depth before tightening. Verify spindle runout with a dial indicator before beginning a cut, as excessive runout accelerates tool wear and reduces surface finish quality. This tool is not center-cutting and requires a pre-drilled or pre-milled entry point for any plunge operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3.000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.25 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)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\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\u003eExtended Reach\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: 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: 0.3 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: 17016201\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559794868530,"sku":"17016201","price":154.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bc02fbdd14cb29a2ef9705c81c46f6d9_bd377769-d9c6-42e4-8fb1-fcd5c813d9c4.jpg?v=1786441300","url":"https:\/\/voomisupply.com\/products\/seco-17016201-roughing-end-mill-3-4-in-4-flute-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
