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.

For the 914 I have on the rotisserie I had to dissect near 2 cars lower half to get what I needed to remove and replace.
I scuff the area to see the recessed areas of the spot welds then I use the spot weld cutters, mini hole saws, with a waxy lubricant or drill bits, depending on the angle of attack. The drill bits were faster. Drill in through top layer then use a HF painters putty knife to split the little hangerons. I have split hundreds of spots with the same blade so far. I also use the large spot weld splitter bars where more muscle is needed and whacked it with a big ass hammer. I had them all sitting there and switched around as necessary. |
