Built from M42 cobalt high-speed steel and coated with TiAlN for heat resistance, this tool handles tough ferrous and non-ferrous alloys where standard HSS tooling wears prematurely. It features a 3\/4 inch mill diameter, four flutes, and a 2 inch length of cut, making it well suited for slotting, peripheral milling, and roughing passes where chip clearance and tool life are priorities. The right-hand cutting and right-hand spiral flute geometry direct chips away from the workpiece. Machinists and tool room professionals install this type of end mill in standard vertical or horizontal milling setups.\u003c\/p\u003e\u003cp\u003eThis roughing end mill is intended for use in production and job-shop milling environments where high material removal rates are needed before finishing passes. The 3\/4 inch shank seats directly into standard ER collets, end mill holders, or hydraulic chucks without adapters. With a regular-length flute and 4-1\/4 inch overall length, it fits most standard knee mills, CNC machining centers, and toolroom mills. The TiAlN coating extends tool life in dry or semi-dry cutting conditions, reducing the need for flood coolant since this tool does not support coolant-through design.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 cobalt material grade for improved red hardness and wear resistance over standard M2 HSS\u003c\/li\u003e\n\u003cli\u003eTiAlN coating reduces heat buildup and extends tool life in dry cutting conditions\u003c\/li\u003e\n\u003cli\u003eFour-flute spiral geometry provides a balance between chip evacuation and surface finish on roughing passes\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard milling spindle compatibility\u003c\/li\u003e\n\u003cli\u003e30-degree maximum helix angle promotes smooth cutting action and reduced chatter\u003c\/li\u003e\n\u003cli\u003eSingle-end design with 3\/4 inch shank diameter matching the mill diameter for direct holder fitment\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 milling applications requiring a 3\/4 inch single-end cobalt tool with a 3\/4 inch straight shank.

Ensure the milling machine spindle is fully powered down and the spindle lock is engaged before changing tooling. Seat the shank fully into the collet or end mill holder and torque the retention hardware according to the holder manufacturer's specifications. Verify runout with a dial indicator before beginning cuts, as excessive runout accelerates edge wear and reduces surface finish quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.75 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: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\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\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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\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\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: 17014843\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563957780786,"sku":"17014843","price":147.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/819cf1c97b0e70fd3a4eca713df9ab3e.jpg?v=1786507857","url":"https:\/\/voomisupply.com\/products\/seco-17014843-roughing-end-mill-3-4-in-4-flute-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
