One of the oldest and very popular power tools are lathes. We use them for both woodworking as well as metal working. A common job of lathe is to rotate the workpiece at a very high RPM while a cutting object trims out unnecessary parts. It essentially reduces the size/diameter of wood/metal.Lathes are relatively expensive tools. But if you have the workload that demands a lathe, then investing in one will definitely be a good decision.
