Spot Weld Cutter

[Froggy77]

Hey guys, what is the part number for the NAPA spotweld cutter? Does it work any better than the Eastwood? I used the smaller Eastwood cutter last weekend, but wasn't real happy with it (see picture). It seemed to start dulling up after 6 welds. Probably my technique. I ended up center punching and then using a 3/8" bit to drill out the weld. Only problem was I was hitting the panel behind. I hate to have to sharpen this thing after every 5 cuts.

Also, what is the part number for the NAPA weld-thru primer....OR better yet, where else can I find that stuff. My NAPA store was less than helpful today.

Thanks!

Did you use oil when you drilled? Not enough could have overheated the bit.

Rust dulls any drill bit real fast.

I bought a set at Sears. They worked great.
