Spot weld cutter

I uses the HF one too and it easily lasted through 2 inner fenders. I flipped the cutter half way into the 2nd side with no change in performance. I center drilled 10 at a time and then used the cutter as the pin skates as noted. Nice clean holes, took about 8-10 seconds a hole at a slower speed IIRC. Nice thing I found is the panel can be put back on and the holes line up to the bump of the old weld, like a giant lego piece. Makes alignment easy if your putting it back on. For busting apart, the heavier tools would probably make more sense.
