Built on the R417.19 toolholder platform, this end mill features a 0.75-inch cutting diameter, a 0.75-inch Weldon flat shank, and an overall length of 4.33 inches. It accepts SPMX 0602-series inserts held in place by a screw-lock method, providing reliable clamping under high-speed cutting conditions. With a 90-degree lead angle and a maximum depth of cut of 0.2 inches, this tool is engineered for true square-shoulder profiling and facing passes. It is installed by machinists and CNC toolroom technicians.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for square-shoulder milling applications on vertical and horizontal machining centers as well as manual knee mills equipped with appropriate spindle tooling. The Weldon flat shank provides positive drive engagement, making it a practical choice for high-torque roughing and finishing passes where shank slippage is a concern. Its 2-flute, single-insert configuration keeps insert cost low for short-run and prototype work. Maximum spindle speed is rated at 32,500 RPM, supporting both conventional and climb milling strategies on a range of ferrous and non-ferrous workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eR417.19 toolholder platform with ISO designation R417.19-00.75-3\u003c\/li\u003e\n\u003cli\u003e90-degree lead angle for true square-shoulder profiling and facing\u003c\/li\u003e\n\u003cli\u003eWeldon flat shank for positive, slip-resistant drive engagement\u003c\/li\u003e\n\u003cli\u003eScrew-lock insert holding method for secure, repeatable insert indexing\u003c\/li\u003e\n\u003cli\u003eCompatible with SPMX 060204, SPMX 0602AP, and APT insert styles\u003c\/li\u003e\n\u003cli\u003eRated to 32,500 RPM for high-speed machining center use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with SPMX 060204, SPMX 0602AP, and APT insert styles.

Before mounting or removing the end mill, ensure the machine spindle is fully powered down and locked out per applicable OSHA lockout-tagout procedures. The Weldon flat shank requires a matching side-lock end mill holder torqued to the holder manufacturer's specification. Inspect the insert pocket and seating surfaces for chips or debris before indexing or replacing inserts.\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: 0.2 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: 3.15 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 4.33 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 90 degrees\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: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SPMX 0602\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete Insert Compatibility\u003c\/strong\u003e: SPMX 060204, SPMX 0602AP, APT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Style\u003c\/strong\u003e: R417.19\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Number\u003c\/strong\u003e: R417.19-00.75-3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 32,500\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Milling\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: 75072183\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559399391538,"sku":"75072183","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8a6d16a47c6393dcbdff03b28374540e.jpg?v=1786431280","url":"https:\/\/voomisupply.com\/products\/seco-75072183-indexable-square-shoulder-end-mill","provider":"Voomi Supply","version":"1.0","type":"link"}
