It is a "specialty" drill bit, that has a relatively small bit at the tip of a bigger bit. The bigger bit is Flat, not angled.
It is designed for the small portion to go through both pieces of the spot weld, but the large part only goes through one piece of the two ( of the metal) Then when you re-use the part you needed, it gives you one solid piece to weld to.
I got mine from Piston.
