Built from solid carbide with a TiCN coating, it delivers the hardness and heat resistance needed for high-speed roughing passes in ferrous and non-ferrous metals. The 5\/8 inch diameter cutter features 3 right-hand spiral flutes with a coarse pitch, a 30-degree maximum helix angle, and a 45-degree chamfer at 0.025 inches chamfer width. Center-cutting geometry allows plunge entry. This tool is used by machinists and tool-and-die professionals running CNC mills or manual knee mills where stock removal rate is the priority.\u003c\/p\u003e\n\u003cp\u003eThe 17004721 suits production and job-shop environments where roughing passes precede finish milling operations. The coarse-pitch flute geometry reduces chip packing in deeper cuts, making it well suited for slotting, profiling, and peripheral milling in steel, stainless, and similar alloys. With a 1-5\/8 inch length of cut and 3-1\/2 inch overall length, it fits standard side-lock, collet, or end-mill holders accepting a 5\/8 inch straight-cylindrical shank. No extended reach configuration is present on this model.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with TiCN coating for elevated hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003e3-flute coarse-pitch spiral geometry promotes chip evacuation during heavy roughing cuts\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design permits direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle balances cutting force and surface finish on roughing passes\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction — standard orientation for conventional CNC setups\u003c\/li\u003e\n  \u003cli\u003eSeries AR330 with M42 material grade designation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for 5\/8 inch straight-cylindrical shank end-mill holders used in CNC machining centers and manual milling machines requiring a single-end roughing end mill.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Seat the shank fully into the holder to the minimum engagement depth recommended by the holder manufacturer. Verify runout with a dial indicator before beginning a cut, and confirm feed and speed parameters match the workpiece material and coating specifications before engaging the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-5\/8 inches (1.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Width\u003c\/strong\u003e: 0.0250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Helix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: AR330\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.003 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.060 to -0.060 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.42 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: 17004721\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559594983730,"sku":"17004721","price":304.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2b13bca16a7ad7362582b9ddde21a889_6aaec7b7-ad84-46b7-b0fd-12600ac7b898.jpg?v=1786436153","url":"https:\/\/voomisupply.com\/products\/seco-17004721-roughing-end-mill-5-8-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
