Ingersoll 6K2K12R50 Shell Face Mill

The Ingersoll 6K2K12R50 is a 12-inch shell face mill featuring a 2-1/2-inch arbor hole and 16 inserts. This shell-type cutter is designed for face milling large flat surfaces, with inserts arranged around the periphery to provide multiple cutting edges and efficient material removal. The 12-inch diameter supports a wide cutting path, enabling substantial material removal in a single pass and helping produce flat finishes on broad faces. The replaceable-insert design means each edge is consumable and can be indexed or swapped as needed, allowing the tool to maintain cutting performance without replacing the entire head. Typical users rely on this configuration for large-diameter milling tasks where a broad cutting width is advantageous. The 6K2K12R50 designation identifies this exact combination of diameter, arbor size, and insert count for users selecting this tooling configuration.
