Built from M42 cobalt high-speed steel and coated with TiCN for improved wear resistance and heat tolerance, this tool handles demanding cuts in ferrous and non-ferrous materials. It features a 3\/4 inch mill diameter, a 2 inch length of cut, and a high-helix spiral flute design at 36 degrees. The right-hand cutting direction and center-cutting capability make it suitable for plunge entry and peripheral milling. Licensed machinists and tool-and-die professionals are the primary users of this end mill in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for use in vertical machining centers, CNC milling machines, and manual knee mills where high metal removal rates are required. The 3-flute roughing geometry reduces cutting forces compared to higher-flute-count tools, making it effective in materials where chip evacuation is critical. The TiCN coating extends tool life in interrupted cuts and abrasive workpiece materials. It fits standard 3\/4 inch collet chucks, end mill holders, and hydraulic toolholders used in typical shop setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 cobalt HSS construction for toughness and heat resistance in heavy cuts\u003c\/li\u003e\n  \u003cli\u003eTiCN coating improves surface hardness and reduces friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e3-flute roughing geometry promotes chip clearance and reduces cutting pressure\u003c\/li\u003e\n  \u003cli\u003eHigh-helix design at 36 degrees improves shear action and surface finish on roughing passes\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capable — supports plunge milling without a pre-drilled entry\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute for use in standard spindle-forward operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit roughing end mill for standard 3\/4 inch end mill holders, collet chucks, and hydraulic toolholders used in CNC and manual milling machines.

Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the shank fully into the holder to the recommended engagement depth and torque set screws or collet nuts per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates wear on roughing geometry.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\u003c\/strong\u003e: TiCN\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: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 36 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\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\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: +0.005 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: RHC752\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\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 17013555\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559703806258,"sku":"17013555","price":140.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4b480b827645cdc3ece6d843bca7ff8a.jpg?v=1786438587","url":"https:\/\/voomisupply.com\/products\/seco-17013555-roughing-end-mill-3-4-in-3-flute-cobalt-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
