...special tool required for creating (or "punching") holes in metallic plates. This tool is utilized to cut through metal plates that are already assembled into some construction, so the use of regular instruments is inefficient or impossible. Punches are presented in a variety of diameters. Operating this device takes several steps. First, you need to drill a small hole in a plate, so the bolt can go through. Next, you have to put on a cutter punch on one side and a die on the other. Some punches require manual force (wrenches), while others utilize an electric drill or a similar utility.
