Part of the Nano Turbo series, this tool features a 3\/4-inch cutting diameter and accepts four XO.X 0602 inserts secured by screw-type clamping. The 90-degree lead angle produces true square shoulders, making it suitable for face milling, shoulder milling, and slotting applications. With a maximum depth of cut of 0.197 inches and a rated maximum spindle speed of 44,000 RPM, this tool is designed for high-speed, high-precision work. A cylindrical shank measuring 5\/8 inch in diameter ensures secure toolholder retention. Integrated through-coolant capability keeps cutting edges cool and aids chip evacuation during continuous cuts.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in CNC machining centers and milling machines where square-shoulder profiling and facing operations are required. The negative rake insert geometry and screw-retention system make it a stable platform for demanding cuts in a variety of workpiece materials. It is well suited for production shops, tool and die operations, and precision contract machining environments where consistent insert indexing and tight tolerances are critical. A licensed machinist or CNC programmer typically selects tooling of this type for ferrous and non-ferrous milling applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-inch cutting diameter with 90-degree lead angle for true square-shoulder milling\u003c\/li\u003e\n  \u003cli\u003eAccepts four XO.X 0602 inserts with screw-type insert retention\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant capability aids chip evacuation and extends insert life\u003c\/li\u003e\n  \u003cli\u003eMaximum spindle speed of 44,000 RPM supports high-speed machining strategies\u003c\/li\u003e\n  \u003cli\u003eNano Turbo series designation with negative rake geometry for stable cutting action\u003c\/li\u003e\n  \u003cli\u003e5\/8-inch cylindrical shank with 5.118-inch shank length for secure toolholder grip\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with XO.X 0602 series inserts.

Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool. Confirm the toolholder bore and clamping mechanism are compatible with the 5\/8-inch cylindrical shank diameter prior to installation. Follow the machine manufacturer guidelines and applicable shop safety standards when setting tool length offsets and maximum RPM parameters.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.197 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.905 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 5.118 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 0.787 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutter Inserts\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: XO.X 0602\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 44,000\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Nano Turbo\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Style\u003c\/strong\u003e: R217.69-06\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Number\u003c\/strong\u003e: R217.69-00.750-0064LAN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.41 pounds\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: 02694898\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560297201970,"sku":"02694898","price":671.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b29cb38d2b4caa60cb8942fec8922d1b.jpg?v=1786450295","url":"https:\/\/voomisupply.com\/products\/seco-02694898-square-shoulder-end-mill-3-4-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
