It carries a 1-inch cutting diameter and accepts two AP.. 1604 series inserts secured by screw clamping. The 90-degree lead angle produces true square shoulders, making it well suited for step milling, face milling, and slotting where a clean 90-degree wall-to-floor transition is required. Overall length is 3.94 inches, with a maximum depth of cut of 0.59 inches. The Weldon flat shank seats firmly in standard end mill holders to resist pull-out under heavy feed loads. Maximum rated speed is 18,400 RPM.\u003c\/p\u003e\n\u003cp\u003eThis end mill is designed for use in CNC machining centers and manual knee mills where indexable tooling is preferred over solid carbide for cost-per-edge efficiency. The two-insert configuration and square-shoulder geometry make it a practical choice for roughing and semi-finishing steel, stainless, aluminum, and cast materials. It is installed and operated by machinists, tooling technicians, and CNC programmers in job shop, production, and maintenance machining environments. The ISO designation R217.69-01.00-3-16 identifies it within the SECO Precimaster and R217 cutter family.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-degree lead angle for true square-shoulder milling and clean wall-to-floor transitions\u003c\/li\u003e\n  \u003cli\u003eAccepts two AP.. 1604 series indexable inserts for cost-effective edge management\u003c\/li\u003e\n  \u003cli\u003eScrew insert-holding method for positive, repeatable insert seating\u003c\/li\u003e\n  \u003cli\u003eWeldon flat shank diameter of 1 inch resists pull-out in high-feed applications\u003c\/li\u003e\n  \u003cli\u003eMaximum spindle speed of 18,400 RPM supports aggressive cutting parameters\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through — external coolant or flood cooling applies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with AP.. 1604 series indexable inserts.

Secure the Weldon flat shank in a properly sized end mill holder and torque the set screw against the flat per the toolholder manufacturer specification. Before mounting or indexing inserts, isolate and lock out the machine spindle following your facility lockout\/tagout procedure. Inspect the insert pockets and clamping screws for debris or damage before each insert change.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 1 inch (25.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.59 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.94 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUsable Length\u003c\/strong\u003e: 2.795 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 Length\u003c\/strong\u003e: 2.67 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1.27 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\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: AP.. 1604\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: 18,400\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Style\u003c\/strong\u003e: R217.69-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Number\u003c\/strong\u003e: R217.69-01.00-3-16\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: 1.5 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 00072158\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563673911602,"sku":"00072158","price":615.92,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e6d5b6b2b1e7abdaf296aa91ebab9c60.jpg?v=1786500956","url":"https:\/\/voomisupply.com\/products\/seco-00072158-square-shoulder-end-mill-1-in-2-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
