Hi,
I don't recommend the spot weld drills with the removable collars, these
have a short life (disintegrated after 8 spots) and they skid a lot. You
also have to watch your drill speed. Try the specially ground cobalt
drills.
I would also remove your glass before you drill out the spots here in case
it cracked and I wouldn't weld with the glass in for the same reason. Also
weld spatter is hot enough to permanently imbed itself into the surface of
the glass.
Comments?
