Part of the Super Turbo series, it features a 1-inch cutting diameter with a 90-degree lead angle that delivers true square shoulders in a single pass. The Weldon flat shank measures 1 inch in diameter with a shank length of 2.43 inches, providing positive drive engagement in the spindle. With through-coolant capability and a maximum spindle speed of 20,800 RPM, this tool is built for aggressive material removal in production environments. Licensed machinists and tooling specialists working with CNC machining centers are the primary installers and operators.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for face milling, slotting, and shoulder milling operations in ferrous and non-ferrous materials. The R217.69-12A toolholder style accepts XO.X 1204.. insert style inserts held by screw clamping. With 3 cutting flutes and a usable length of 2.858 inches, it handles moderate-depth passes efficiently. The overall assembly length is 4 inches, making it compatible with standard CNC tool-change systems and shrink-fit or side-lock holders configured for 1-inch Weldon shanks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e90-degree lead angle produces true square shoulders in a single pass\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design directs fluid directly to the cutting zone for improved chip evacuation and tool life\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank provides positive anti-pullout drive engagement at high feed rates\u003c\/li\u003e\n\u003cli\u003eMaximum spindle speed of 20,800 RPM supports high-productivity roughing and semi-finishing strategies\u003c\/li\u003e\n\u003cli\u003eScrew-clamp insert retention (XO.X 1204.. style) allows fast, repeatable insert indexing without special tools\u003c\/li\u003e\n\u003cli\u003eISO designation R217.69-01.00-3-12-3AN for cross-reference and insert sourcing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with the R217.69-12A toolholder configuration and XO.X 1204.. insert style.

Ensure the machine spindle is fully stopped and the CNC program is in a safe state before loading or unloading the tool. Verify the Weldon flat is correctly aligned with the set screw in the holder before tightening to prevent pullout under load. Confirm insert seating and screw torque according to the insert manufacturer's toolholder documentation before running at elevated feed rates or spindle speeds.\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: Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.43 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1.57 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUsable Length\u003c\/strong\u003e: 2.858 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\u003eMaximum RPM\u003c\/strong\u003e: 20,800\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: XO.X 1204..\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Style\u003c\/strong\u003e: R217.69-12A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\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: Super Turbo\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Number\u003c\/strong\u003e: R217.69-01.00-3-12-3AN\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: 02688954\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563827855666,"sku":"02688954","price":742.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/568108b0c7206ef609a6395697eb6386.jpg?v=1786504289","url":"https:\/\/voomisupply.com\/products\/seco-02688954-indexable-square-shoulder-end-mill-1-in","provider":"Voomi Supply","version":"1.0","type":"link"}
