A stepped tool means the cutting diameter is larger than the shank diameter. This facilitates a larger cutting diameter for surfacing with spindles using smaller collet sizes. The single flute version is a good solution for heavier cuts with higher torque spindles. These tools are perfect for aluminum, brass, plastics and exotic composites.

Face mill tools are designed to remove a skim coat off the top of a surface. They generally are not designed for roughing and are very effective in truing up your material or quickly providing an excellent surface finish. These larger diameter long-life, micro-grain carbide tools are available in various cutting diameters and lengths, shank diameters, and geometries for specialty applications.
