Product Description

The SECO 02685794 is an indexable chamfer angle face mill designed for precision milling operations in metalworking environments. Built to Series R220.48 specifications, it accepts ON.U.09 inserts secured by a wedge holding method and features a right-hand cutting direction. The cutter spans a minimum cutting diameter of 3.15 inches and a maximum body diameter of 3.74 inches, with a maximum depth of cut of 0.236 inches. Six flutes and a normal pitch configuration make this tool well-suited for consistent stock removal on flat surfaces. It is installed by machinists and tool and die professionals working with CNC and manual milling machines.

This face mill is intended for use in production and job shop environments where chamfer angle face milling is required. The 1-inch arbor hole diameter and 0.38-inch keyway width provide positive drive engagement and accurate tool positioning on compatible arbors and spindles. With a maximum rated speed of 4,400 RPM and no coolant-through capability, it is suited for dry or externally cooled milling setups. The 1.969-inch overall height fits standard tooling envelopes for horizontal and vertical milling applications.
