Built to a 3\/4 inch diameter with a 3\/4 inch straight-cylindrical shank, it delivers stable cutting performance with minimal deflection. The three-flute coarse-pitch geometry promotes efficient chip evacuation during heavy cuts. With a 1 inch length of cut and 3 inch overall length, this single-end tool is suited for slotting, profiling, and roughing passes where speed and chip load are the priority. Center-cutting capability allows plunge entry without a pilot hole. The bright, uncoated finish is appropriate for a wide range of ferrous and non-ferrous materials. Machining professionals and tool crib operators will recognize this as a production-grade roughing tool.\u003c\/p\u003e\u003cp\u003eThe 17004690 is used in CNC vertical and horizontal milling centers as well as manual knee mills running appropriate feeds and speeds for solid carbide. Its right-hand cut and right-hand spiral flute direction are standard for conventional and climb milling. The coarse pitch and 30-degree maximum helix angle reduce cutting forces and heat buildup during roughing passes in steel, cast iron, and similar materials. This tool is part of the SECO AR330 series and is appropriate for job shops, production floors, and maintenance machining environments where a reliable roughing end mill with consistent dimensional tolerances is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/4 inch diameter solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003e3-flute coarse-pitch design promotes aggressive chip evacuation during roughing\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows direct plunge entry\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand spiral flute direction for standard milling operations\u003c\/li\u003e\n\u003cli\u003e30-degree maximum helix angle reduces cutting forces and heat in ferrous materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for a broad range of workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide roughing end mill in the SECO AR330 series, compatible with standard 3\/4 inch collet chucks, end mill holders, and milling arbors used in CNC and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom professional. Secure the shank fully within the holder to the recommended engagement depth per the toolholder manufacturer's specifications, and ensure runout is checked before production cuts. Always power down and lock out the machine spindle before changing tooling. Do not exceed the tool's rated cutting parameters for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inch (0.75 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: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42\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 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eMaximum Helix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Width\u003c\/strong\u003e: 0.025 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 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\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\u003eWeight\u003c\/strong\u003e: 0.56 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: 17004690\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563924226354,"sku":"17004690","price":290.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5551553355fa070f895458f07c39c0f2.jpg?v=1786506922","url":"https:\/\/voomisupply.com\/products\/seco-17004690-roughing-end-mill-3-4-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
