Life is good. Oh, don't forget to punch mark your drill location, but I probably didn't have to remind you of that though. Alright, now a word about breaking through the drilled hole while drilling. This is kind of important, especially if breaking wrists or thumbs and getting bruised by spinning unclamped metal smarts too much. Whenever a drill is beginning to break through the far side of a piece of metal, always back off the pressure a bit.
Many folks do the opposite and find themselves in serious trouble.
If the final pass is lightly taken, then whatever metal is trying to grab the bit is only a few thousands thick and is easily defeated, even if you are not clamping the work down on the press. That drill can spin itself around and your wrist with it if you aren't careful. Oh, by the way, it always helps to use a lubricant when using a large drill bit except into cast iron, then you drill that dry. Well, tapping is an operation that requires one to be very sensitive with their fingertips. When starting to tap a hole, the taper on a plug tap easily works itself into the hole then begins to resist.
