Indexable turning and profiling toolholders are used with lathes or CNC turning machines to size, shape, or add features such as grooves or contours to workpieces. They have a shank that mounts to the machine and a cutting head that holds an indexable insert.
Indexable carbide tooling is the third type of tooling for lathes. Indexable tooling uses steel tools, with a screw or clamp securing a carbide insert to the end of the tool. Indexable carbide tools and inserts are widely available, as they are almost unanimously used in CNC Turning.
