You can see a picture of one at the URL below.  They are basically a small 
hole saw with a spring loaded center.  The center is there to help you 
place the bit and retracts as you cut so you don't the the force or torque 
required to drill through the area hardened by the spot weld  This avoids 
having to push hard enough to distort the sheet metal, allowing you to 
salvage both parts.

Thanks,
Bill
