Overview

The MITSUBISHI 545879 is a solid carbide corner radius end mill designed for demanding material removal in steel, stainless steel, and high-temperature alloys. The 4-flute, single-end geometry features a 0.0787 inch (2.00 mm) corner radius and an AlTiSiN PVD coating that supports both roughing and finishing operations in a single tool. A variable helix and variable index design reduce harmonic chatter and improve surface finish at aggressive feed rates. This tool is installed by machinists and CNC tooling professionals in production and job-shop environments. The 545879 is suited for vertical and horizontal machining centers running steel, alloy steel, carbon steel, cast iron, stainless steel, titanium alloy, and heat-resistant superalloys. The long-length configuration and reduced neck diameter of 11.70 mm (0.4606 inch) make it appropriate for applications requiring extended reach into pockets or deep-wall features. The straight-cylindrical shank with h6 tolerance ensures consistent tool holding in precision collet chucks and hydraulic holders. It is not center-cutting and should not be used for plunge entry.
