Seco 02694898 Square-shoulder End Mill 3/4 in 4 Flute

Product Description

The SECO 02694898 is an indexable square-shoulder end mill built for precision milling operations in metalworking and machining environments. Part of the Nano Turbo series, this tool features a 3/4-inch cutting diameter and accepts four XO.X 0602 inserts secured by screw-type clamping. The 90-degree lead angle produces true square shoulders, making it suitable for face milling, shoulder milling, and slotting applications. With a maximum depth of cut of 0.197 inches and a rated maximum spindle speed of 44,000 RPM, this tool is designed for high-speed, high-precision work. A cylindrical shank measuring 5/8 inch in diameter ensures secure toolholder retention. Integrated through-coolant capability keeps cutting edges cool and aids chip evacuation during continuous cuts.

This end mill is intended for use in CNC machining centers and milling machines where square-shoulder profiling and facing operations are required. The negative rake insert geometry and screw-retention system make it a stable platform for demanding cuts in a variety of workpiece materials. It is well suited for production shops, tool and die operations, and precision contract machining environments where consistent insert indexing and tight tolerances are critical. A licensed machinist or CNC programmer typically selects tooling of this type for ferrous and non-ferrous milling applications.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool. Confirm the toolholder bore and clamping mechanism are compatible with the 5/8-inch cylindrical shank diameter prior to installation. Follow the machine manufacturer guidelines and applicable shop safety standards when setting tool length offsets and maximum RPM parameters.
