need some help here

[a192074m]

hey it's been awhile since i posted anything up, but i got a question that hopefully you guys can help me on.  On my project charger i know I'll haveta remove some sheetmetal that is spot welded together and the other day I was looking around on a forum for 3rd gen chargers and they had a spot weld cutter.. it kinda looks like a cross between a punch and a wood bore.  So i went looking and all the places around my area from auto stores to even specialty stores and they look at me like i was crazy!!        So my questions are: Does anybody know what I'm talking about and where can i get one???  here's a picture of what it looks like, thanks

They do not cut 2nd layer of sheet metal, giving you area to weld onto later on.
Any body shop supply store should have them

I like the blair http://www.blairequipment.com/Spotweld_Cutters/Spotweld_Cutters.html work great and lasts long.

A couple years ago I tried NAPA bluepoint ones and they lasted about as long as the Blair ones.

i use the same ones silver posted up. i like them because if you break a tip you can use a 3" cut off wheel and re cut the tip and keep on using them. I actually found mine at a Lowe's I think the last time i got them they were  40 bucks for a pack of them, i think 6 in a pack. its been awhile since I've had to buy any.

Most good paint supplie stores should carry them. Thats where I get mine. Tool trucks also carry them. Eastwood carries them for a last resort. Or sometimes I use a cut off wheel. To use a cut off wheel you grind around the edges of the weld after you have ground all the spots welds off and remove the panel then you can grind it smooth.
