Seco 02694887 Indexable Square-shoulder End Mill

Product Description

The SECO 02694887 is an indexable square-shoulder end mill designed for precision milling operations in metalworking and machining environments. Built on the Nano Turbo series platform, it features a 0.5-inch cutting diameter, a 90-degree lead angle, and accommodates 3 XO.X 0602-style inserts secured by screw clamping. The through-coolant design supports heat management and chip evacuation during high-speed cuts. With a maximum RPM rating of 54,000, this toolholder is suited for demanding production environments where rigidity and consistent insert positioning are critical. It is installed by machinists and CNC tooling technicians as part of a modular cutting tool setup.

This end mill is intended for square-shoulder milling applications where a true 90-degree wall angle is required. The cylindrical shank measures 0.5 inches in diameter with a shank length of 1.654 inches, making it compatible with standard ER and side-lock toolholding systems used in CNC machining centers. The R217.69-06A cutter body designation identifies it within the SECO modular indexable tooling system. Typical applications include face milling, slot milling, and step milling in ferrous and non-ferrous workpiece materials. The Nano Turbo series is commonly used in high-speed, light-radial-engagement finishing and semi-finishing passes.

Key Features

Compatibility

Uses XO.X 0602 insert style. Cutter body style is R217.69-06A. ISO number R217.69-00.50-0-06-3AN. Designed for use in CNC machining centers equipped with toolholders accepting a 0.5-inch cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the tool change sequence is complete before handling the toolholder. Inserts must be seated fully in the pocket before tightening the clamping screw to the appropriate torque per the insert manufacturer specification. Verify through-coolant port alignment with the machine spindle coolant supply before initiating a cutting cycle.
