Re: Spot weld drills

Craig;
I'm guessing here a little bit but this is a combination of what I know about 
metallurgy and what I have seen calling on autobody shops in a later life.
I have seen a lot of the circular type which tut around the weld in use in 
shops.  I would guess that they found that it is easier to cut around the 
weld than drill through it as the welding process will tend to harden the 
metal locally makeing it difficult to drill through.  FWIW
