Part of the Super Turbo series and identified by ISO designation R217.69-01.00-0-12-2AN, this tool accepts two XO.X 1204.. inserts secured by screw clamping. It runs a 1-inch cutting diameter with a maximum depth of cut of 0.433 inches and an overall length of 6.69 inches. Through-coolant capability supports extended tool life and chip evacuation at elevated spindle speeds up to 20,800 RPM. Machinists and tool-and-die professionals working in production environments will find this tool suited to high-feed shoulder and face milling work.\u003c\/p\u003e\u003cp\u003eThis end mill is designed for square-shoulder milling applications in ferrous and non-ferrous materials where a perpendicular wall-to-floor relationship is required. The 1-inch cylindrical shank with a 5.32-inch shank length accommodates standard toolholder bores in CNC machining centers. The two-insert configuration keeps cutting forces manageable while maintaining material removal rates appropriate for roughing and semi-finishing passes. The 1.37-inch head length provides clearance geometry suited to pocket and contour milling operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e90-degree lead angle for true square-shoulder milling\u003c\/li\u003e\n\u003cli\u003eAccepts two XO.X 1204.. indexable inserts with screw-lock retention\u003c\/li\u003e\n\u003cli\u003eThrough-coolant channels support chip evacuation and insert longevity\u003c\/li\u003e\n\u003cli\u003eMaximum spindle speed of 20,800 RPM for high-productivity CNC applications\u003c\/li\u003e\n\u003cli\u003e1-inch cylindrical shank compatible with standard ER and hydraulic toolholders\u003c\/li\u003e\n\u003cli\u003eSuper Turbo series cutter style R217.69-12A for consistent insert seating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with XO.X 1204.. series indexable inserts as specified by SECO for the R217.69-12A cutter style.

Ensure the machine spindle is fully stopped and the control is in an e-stop or tool-change state before mounting or demounting the cutter. Torque insert screws using the appropriate SECO Torx key to seat inserts fully without over-torquing. Verify runout at the cutting diameter with a dial indicator before committing to a production cut.\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\u003eOverall Length\u003c\/strong\u003e: 6.69 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: 1 inch\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: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutter Inserts\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: XO.X 1204..\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\u003eMaximum RPM\u003c\/strong\u003e: 20,800\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Series\u003c\/strong\u003e: Super Turbo\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Number\u003c\/strong\u003e: R217.69-01.00-0-12-2AN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.4 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: 02688853\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559527907634,"sku":"02688853","price":648.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/49b19d7ea7a3d22d06520d036b838e47.jpg?v=1786434543","url":"https:\/\/voomisupply.com\/products\/seco-02688853-square-shoulder-end-mill-1-in-2-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
