Part of the Super Turbo series, it uses the R217.69-12 toolholder style and accepts XO.X 1204 insert style inserts, with full compatibility for XOEX and XOMX insert types secured by screw-clamp holding. The tool features a 1-inch cutting diameter, a maximum depth of cut of 0.433 inches, and a 90-degree lead angle for true square-shoulder profiling. Constructed from steel, it supports through-coolant delivery to manage heat and chip evacuation during high-feed passes. This tool is installed and used by machinists and CNC operators in production and job-shop settings.\u003c\/p\u003e\u003cp\u003eThe 02688854 is suited for square-shoulder milling, profiling, and slotting applications on ferrous and non-ferrous workpiece materials. Its 3-flute, negative-rake geometry supports aggressive material removal while maintaining stable insert seating. The through-coolant feature makes it well suited for deeper pocketing and finishing passes where thermal management is critical. With a maximum spindle speed of 20,800 RPM, it is compatible with modern CNC machining centers running high-speed milling programs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-inch cutting diameter with 0.433-inch maximum depth of cut for square-shoulder profiling\u003c\/li\u003e\n\u003cli\u003e90-degree lead angle produces true 90-degree shoulders in a single pass\u003c\/li\u003e\n\u003cli\u003eAccepts XO.X 1204 inserts; compatible with XOEX and XOMX insert families\u003c\/li\u003e\n\u003cli\u003eThrough-coolant capability for improved chip evacuation and tool life in deep cuts\u003c\/li\u003e\n\u003cli\u003e3-flute, negative-rake design for stable, high-feed indexable milling\u003c\/li\u003e\n\u003cli\u003eMaximum spindle speed of 20,800 RPM suitable for modern CNC machining centers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with the R217.69-12 toolholder style.

Ensure the machine spindle is fully stopped and power is locked out before mounting or removing the toolholder. Verify insert seating and screw torque per the toolholder manufacturer guidelines before initiating a cut. Confirm coolant lines are clear and through-coolant is active before running at elevated RPM.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.433 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 6.69 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 5.32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1.37 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutter Inserts\u003c\/strong\u003e: 3\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\u003eInsert Style\u003c\/strong\u003e: XO.X 1204\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: XOEX, XOMX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Style\u003c\/strong\u003e: R217.69-12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Super Turbo\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 20,800\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Number\u003c\/strong\u003e: R217.69-01.00-0-12-3AN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 02688854\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51557663768882,"sku":"02688854","price":678.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b7c81eb9247ad44db311536129d9a43a.jpg?v=1786392344","url":"https:\/\/voomisupply.com\/products\/seco-02688854-indexable-square-shoulder-end-mill","provider":"Voomi Supply","version":"1.0","type":"link"}
