I have been drilling spot welds as I work on my car and it occured to me that there may be a better way (or maybe I am being to picky). I am curious what everyone else uses.
I have been using a spot weld cutter. It looks like a short drill bit with a pilot point and little cutters along the edge. It will cut through the top layer or steel but not the back layer (usually). They will cut about 10 welds before being hoplessly dull. When I was buying them at $5/bit it was fine but that company went out of business and the ones I find now are $25/bit. Are these the right tools to use or should I be just using a drill bit allthe way through the weld. Any help or tool suggestions would be appreciated.

I just did my floor pans recently and used a standard bit (sorry don't recall the size). I drilled until the bit got dull and then ran it through the bit sharpener, worked like a champ. The only issue is you can't drill quite as deep and I used a chisels to get under the pan and pop the last fringes of metal holding on. One bit, worked it down to a nub (IMG:style_emoticons/default/biggrin.gif)
