What type of cutting tool is used for shaping metal on a lathe?

A turning tool is specifically designed for shaping metal on a lathe, where it removes material from the workpiece as it rotates. This tool is essential for processes like turning, facing, and boring, allowing operators to create cylindrical shapes and precise dimensions on various types of materials, particularly metals.

In contrast, a drilling tool is typically used to create holes and is not designed for linear shaping or turning operations. A milling cutter is employed on a milling machine for creating flat or contoured surfaces, which is not suitable for the rotational shaping performed by a lathe. A grinding wheel is used for grinding operations, which is a different process focused on finishing surfaces rather than shaping material. Thus, the turning tool is the appropriate choice for performing the shaping function on a lathe.
