Seco 02689813 Square-shoulder Face Mill 2 in 5 Insert

Product Description

The SECO 02689813 is an indexable square-shoulder face mill designed for high-productivity milling operations in metal cutting applications. Built around the Super Turbo series platform, this cutter accepts five XO X1204 inserts and delivers a 2-inch maximum cutting diameter with a maximum depth of cut of 0.433 inches. The 0/90 lead angle geometry produces true 90-degree shoulders, making it well suited for step milling, slotting, and profiling. Through-coolant capability supports chip evacuation and tool life in demanding cuts. The arbor hole diameter measures 0.75 inches, and overall tool height is 1.57 inches. This tool is typically installed and operated by machining professionals and CNC programmers in production and job-shop environments.

The SECO 02689813 is applied in CNC machining centers and manual milling setups where square-shoulder accuracy and surface finish consistency are required. Supported operations include helical interpolation, ramping up to a 2-degree maximum angle, and slotting. The positive axial and negative radial rake configuration balances cutting forces for stable performance across a range of workpiece materials. Clamp and screw insert holding secures indexable inserts during aggressive passes.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC technician. Ensure the machine spindle is fully stopped and all stored energy is released before mounting or indexing inserts. Verify arbor and spindle interfaces are clean and free of burrs before seating the cutter. Follow the insert manufacturer torque guidelines when securing clamp screws, and confirm runout with a dial indicator before beginning production cuts.
