Tool/Step. Description. Milling Cutters (excluding end mills): Used for a variety of operations from facing styles (squaring and smoothing faces), as well as cutting angles and shapes, as well as grooves and slots. Slitting Cutters: Used for cutting a narrow slit into material, not used for removing lots of material.
