Where i served my time, we worked on stainless steel only, large machine bodies that were grit/sand blasted before we got them. We had to drill and tap various holes in them by hand, if you ran a drill bit continuously it would heat up and burn out the point. So we used to hit the drill button for a second, then stop for a second, the bit never got hot and did not burn out.
