Last week, I had all sorts of issues with removing spot welds. The bit was walking all over the place, so I decided to drill pilot holes - which wore out the center post guide and it snapped off. Then I attempted repair with the nail portion of a pop-rivet, which lasted all of two welds. Then I tried a real nail, and it got me through both outer cowl covers. Between the batteries on the drill wienering out way too fast and the spot weld bit issues, it took me almost 5 hours to get just the outer cowl covers off.
Yesterday, I found an old Dremel bit (with the grinding part snapped off) and used it for the center guide. After welding a blob on the end (to keep it from falling out of the bit), things worked really well. It's hardened and didn't get worn out from the pilot holes. SCORE! Still had the battery issues, but I did manage to get the other cowl pieces apart and the left piece of firewall scrap separated from the apron and frame rail on the driver side. Now, I just need to work on getting the torque box loose and then move to the passenger side.
