Seco 02504119 Indexable Square-shoulder End Mill 1/2 in

Product Description

The SECO 02504119 is an indexable square-shoulder end mill designed for precision milling operations requiring a true 90-degree lead angle and tight shoulder profiles. Part of the Nano Turbo series, this toolholder accepts XO.X 0602 insert style and runs up to 54,000 RPM, making it well-suited for high-speed finishing and semi-finishing passes in steel, stainless, and non-ferrous materials. It features a 1/2-inch cutting diameter, a maximum depth of cut of 0.197 inches, and a 1/2-inch cylindrical shank. Through-coolant capability supports chip evacuation and tool life in demanding cutting conditions. Licensed machinists and CNC programmers in production and job-shop environments are the primary users of this tool.

This end mill is intended for use in CNC machining centers and milling machines where a square-shoulder profile is required. The R217.69-06A cutter style fits standard toolholding systems that accept 1/2-inch cylindrical shanks. The 3-flute, 3-insert configuration provides a balance of chip clearance and surface finish at elevated spindle speeds. Through-coolant delivery makes this tool practical for slotting and peripheral milling where heat and chip buildup are concerns. Typical applications include shoulder milling, face milling at shallow depths, and profiling passes in precision component manufacturing.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and the tool changer is disabled before mounting or removing the toolholder. Insert seating and screw torque should follow the insert manufacturer guidelines provided with the XO.X 0602 inserts. Verify coolant port alignment with the machine spindle before initiating through-coolant operation.
