Bud used conventional punches, enlarged the holes, then used larger punches.  I forget how long Bud spent on this container, but it was longer than either of us thought it would take.

Finally, I told Bud that I would get my new punches out of the truck so we could try them. I brought him a 1/4" X 12" and a 5/16" X 12".  The punch set comes with several length punches, there are 4 diameter sizes (and yes my name is spelled wrong on the handles, a common mistake I have lived with all my life, I don't care anymore). 
             
The safe was opened in seconds after I handed the two punches to Bud.  Good tools do make a difference.
            





 

A good friend Van Schneider and myself are drilling a Red Label GSA Cabinet.  The safe are up many SA, MP#, Champion and Mr. Twister drill bits.  It also ruined a diamond core at high speed with light pressure.
              
When I got involved, there were at least 20 spent drill bits laying in front of the container.  I pulled out the Metabo 1015 that I had bought from Bob Stably several months ago.  I set the RPM at 550 and the torque at 7.  The drill was quite and easy to hold on to since it is not real heavy.  45 minutes to an hour later, and two more diamond core bit, we broke through.  The 1015 kept Van and I from breaking a sweat, it truly is the best drill I have ever worked with.  If you ever have the chance to by one, jump on it.  You will not be sorry.
