Part of the Super Turbo series, it accepts 8 inserts in the XOEX1204 or XOMX 1204 style and features a 0\/90 degree lead angle that produces true 90-degree shoulders in a single pass. The cutter measures 4 inches in cutting diameter with a 1.5-inch arbor hole and an overall height of 2 inches. Maximum depth of cut is 0.433 inches. Through-coolant capability supports extended tool life and chip evacuation at elevated feed rates. This mill is intended for use by machining professionals on CNC milling machines and machining centers.\u003c\/p\u003e\u003cp\u003eThe 02689826 is suited for operations including helical interpolation, ramping, and slotting. Its positive axial and negative radial rake geometry balances cutting force with edge stability, making it appropriate for both roughing and semi-finishing passes on square-shoulder features. The 0.50-degree maximum ramping angle supports controlled plunge-entry paths when direct access to the workpiece face is limited. Machinists working in job shop and production environments will find the 8-insert configuration delivers competitive metal removal rates on mid-size spindles with 1.5-inch arbor interfaces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-inch cutting diameter with 0.433-inch maximum depth of cut per pass\u003c\/li\u003e\n\u003cli\u003e0\/90 degree lead angle for true square-shoulder profiles\u003c\/li\u003e\n\u003cli\u003eAccepts 8 inserts — compatible with XOEX1204 and XOMX 1204 insert styles\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design improves chip evacuation and extends insert life\u003c\/li\u003e\n\u003cli\u003ePositive axial and negative radial rake for balanced cutting forces\u003c\/li\u003e\n\u003cli\u003eSupports helical interpolation, ramping, and slotting tool paths\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with XOEX1204 and XOMX 1204 insert styles.

Ensure the machine spindle is fully stopped and locked out before mounting or removing the cutter body. Confirm the arbor and hub interfaces are clean and free of chips or burrs before assembly. Insert clamping screws should be torqued according to the insert manufacturer's specified procedure using calibrated tooling — do not rely on feel alone.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Hole Diameter\u003c\/strong\u003e: 1.5 inches\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\u003eOverall Height\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Inserts\u003c\/strong\u003e: 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 0\/90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive (Axial), Negative (Radial)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: XOEX1204, XOMX 1204\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Style\u003c\/strong\u003e: R220.69\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Super Turbo\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Applications\u003c\/strong\u003e: Helical Interpolation, Ramping, Slotting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Ramping Angle\u003c\/strong\u003e: 0.50 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 90.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKeyway Width\u003c\/strong\u003e: 16.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.7 pounds\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: 02689826\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559490847026,"sku":"02689826","price":1525.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/91fe29da1da6bf22555c16ae79bb41c3.jpg?v=1786433705","url":"https:\/\/voomisupply.com\/products\/seco-02689826-square-shoulder-face-mill-4-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
