In soft or pre-hard materials a ball nose carbide tool or ball nose insert tool can be used. The advantage of the large tool radius is that a good finish can be achieved with a larger step-down. In harder materials a tool with a smaller corner radius (Toroid or bull nose tool or insert) should be used to minimize tool deflection. On steep or straight (perpendicular) walls a back drafted tool should be used. Choose a Z-level or spiral cutter path to keep the cutting edge constantly in the cut. This strategy reduces the number of times the cutting edge of tool or insert goes into or exits the cut and is subjected to a thermal and load shock; it helps to prevent tool life reduction and insert failure.
