Drilling large holes in metal can be difficult as many lager drill bits use taper shanks, which will not fit in regular drill chucks. Hole saws work well and fit into most standard chucks on most hand drills or pillar drills. Here I cut a 26mm hole in some 5mm thick mild steel using a hole saw and a pillar drill.
