Seco 02504118 Indexable Square-shoulder End Mill 3/8 in

Product Description

The SECO 02504118 is an indexable square-shoulder end mill designed for precise 90-degree shoulder milling operations in metalworking applications. Built on the Nano Turbo series platform, this tool features a 3/8-inch cutting diameter, a maximum depth of cut of 0.197 inches, and a 3/8-inch cylindrical shank with an overall length of 2.165 inches. It accepts XO.X 0602 insert style inserts held in place by a screw-lock mechanism, providing consistent and repeatable cutting performance. With a maximum spindle speed of 60,000 RPM, the 02504118 suits high-speed machining centers and compact milling setups where tight tolerances and square shoulders are required. Licensed machinists and CNC tooling professionals typically specify and install this toolholder.

This end mill is intended for use in CNC machining centers and milling machines where square-shoulder profiling, slotting, and peripheral milling are common operations. The 90-degree lead angle produces true square walls, making it suitable for precision component work in steel, aluminum, and other machinable metals. The through-coolant design directs cutting fluid directly to the insert cutting edge, aiding chip evacuation and extending insert life in demanding material removal applications. It is well-suited for production environments where compact tooling is required in confined workspaces or smaller-bore spindles.

Compatibility

Designed for use with XO.X 0602 series inserts and compatible with R217.69-06A cutter style toolholder configurations. ISO designation R217.69-00.375-0-06.2A. Verify insert style and cutter body compatibility before ordering inserts separately.

Installation Notes

Installation is performed by qualified CNC machinists or tooling technicians. Ensure the spindle is fully powered down and the machine is in a safe locked-out state before mounting or removing the toolholder from the spindle. Confirm shank diameter compatibility with the collet or chuck before seating, and torque the clamping screw to the toolholder manufacturer specification using the appropriate Torx or hex key. Verify insert seating and clamping screw torque on all inserts before initiating a cutting cycle.
