Plunge milling As the name suggests, a specialized plunge mill cuts into the material in the Z direction, then withdraws and plunges again about half a diameter away. Plunge milling can be done from an edge or the outside of a hole, or the tool can gradually ramp its way into the workpiece. Repeated plunges can remove a lot of material.
