Part of the Super Turbo series, it accepts XO.X 1204.. style inserts held in place by a screw-lock mechanism. The tool features a 3\/4-inch cutting diameter, a 90-degree lead angle, and a maximum depth of cut of 0.433 inches. Through-coolant capability supports extended tool life and chip evacuation during high-speed cuts. With a maximum spindle speed of 23,200 RPM and two cutting inserts, this toolholder is built for productive square-shoulder milling on machining centers and manual mills. The Weldon flat shank provides positive drive engagement and reduces pull-out risk during aggressive cuts.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for square-shoulder milling applications in job shops, production facilities, and toolrooms. The R217.69-12A toolholder designation places it within a well-established indexable milling platform. A 3\/4-inch Weldon flat shank, 2.20-inch shank length, and 3.38-inch overall length make it compatible with standard toolholding setups on vertical and horizontal machining centers. The through-coolant port allows direct delivery of cutting fluid to the insert zone, which is particularly useful when machining steel, stainless, or cast iron at elevated feed rates.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/4-inch cutting diameter with 0.433-inch maximum depth of cut\u003c\/li\u003e\n\u003cli\u003e90-degree lead angle for true square-shoulder milling profiles\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design for improved chip evacuation and insert life\u003c\/li\u003e\n\u003cli\u003eAccepts XO.X 1204.. insert style with screw-lock retention\u003c\/li\u003e\n\u003cli\u003eMaximum spindle speed of 23,200 RPM\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank provides positive rotational drive and pull-out resistance\u003c\/li\u003e\n\u003cli\u003e2-insert, 2-flute configuration for balanced cutting performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with XO.X 1204.. insert style inserts.

Ensure the machine spindle is fully stopped and the machine is locked out before mounting or changing inserts. Secure the Weldon flat shank in a compatible toolholder to the machine manufacturer's specified drawbar torque. Verify insert seating and screw torque before initiating any cutting cycle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.75 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\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.20 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3.38 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUsable Length\u003c\/strong\u003e: 2.362 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1.17 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 Style\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: 23,200\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Style\u003c\/strong\u003e: R217.69-12A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Number\u003c\/strong\u003e: R217.69-00.75-3-12-2AN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Super Turbo\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Milling\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.44 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: 02688950\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560719253810,"sku":"02688950","price":622.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cb73eded06752bc2192e72cdf212e9c1.jpg?v=1786456151","url":"https:\/\/voomisupply.com\/products\/seco-02688950-indexable-square-shoulder-end-mill-3-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
