Seco 02685793 Indexable Face Mill 2.48in 5 Insert

Product Description

The SECO 02685793 is an indexable chamfer angle face mill designed for facing operations on machining centers and milling machines. Built to Series R220.48 standards, it accepts 5 ON.U09 inserts and delivers a maximum depth of cut of 0.236 inches across a minimum cutting diameter of 2.48 inches and a maximum cutting diameter of 3.071 inches. The cutter runs right-hand direction with a negative rake angle of -8 degrees, making it well-suited for aggressive material removal on ferrous and non-ferrous workpieces. Machinists and tooling technicians working in production shops or job shops are the primary installers and operators of this tool body.

This face mill fits horizontal and vertical milling setups where a 3/4-inch arbor hole is available. It is used in facing applications requiring a 40-degree chamfer angle geometry. With a maximum rated speed of 4,900 RPM, it is appropriate for both conventional and CNC milling operations in production environments. The overall height of 1.575 inches and hub diameter of 1.26 inches suit standard arbor and adapter configurations common in mid-size machining operations.
