[QUOTE="bird dog, post: 1755440, member: 5381"] Yes go with the slugger type. Much much quicker and probably cheaper per hole.. I did thousands of holes through beams back when I was a young guy. The cutters thru that thin of metal will make a lot of holes and they can be resharpened for about 1/4th the price of a new bit. Ask your welding supply or some of the local fab shops whats the best brand going, where to buy the cutters and who close by sharpens them. For that thin of metal, use a 1" long cutter. Buy WD40 by the gallon and a spray bottle. When drilling on a vertical surface, have a operator and a helper. One guy holds the tool in position while the other guy flips the switch for the magnet. The cutters have a center pin that sticks out the end for alignment and then ejects the slug. [/QUOTE]
