Spot weld cutter

[DRJDVM's '69]

I'm looking for a spot weld cutter/bit.

I've looked at several at Eastwood and was wondering if anyone had some suggestions. It looks like there at basically 2 types.... one is basically a large drill bit and the other has a drill bit in the center and a larger cutting ring on the outside of that.

So any tips on which works the best with the least amount of damage to the remaining sheetmetal. I'm getting ready to get rid of the rusty trunk pan in the Barracuda.

I have used both and the one which resembles a large drill bit/mill bit is the S#$T!!! The other one which looks like a small hole saw dulls quickly and wears the tip out. With the bit version cleanup of the old spot weld is simple because you removed all the material as with the other one you still need to remove the spot weld with a grinder. also with the bit version I removed both floor pans before it started showing signs of dulling (using cutting oil and not over heating the bit). Hope this helps.

blair cutter works the best, i like to use a 1/8 bit to drill the center of spot welds, this locks the blair cutter tip in to make for a clean cut, then when welding back together the 1/8 hole on the inner panel gets welded up easily.

I used the snap-on ones, 100 dollars for 4 they worked great and are guaranteed.( the main body not the 1/8 in. drill bit) also can be sharpened on bench grinder.

Most body shop supply stores carry these. I picked up one to use when I removed my upper dash panel. They work great. But it wasn't $100.

I was looking at the car last night trying to figure this out. Could somone post a link to the various types of tools for this so I know what I'm looking for.

I did all the work on my Jeeps with an air chisel....yikes, tons of work and it really jacked up the panel. This sounds like a better way to go. I just need to know which tool and where to get it.

I looked on Eastwood and found these..

I just ordered the one at the top.... the 3/8 inch "Pro"

I've had hit and miss results with stuff off Eastwood. Sometimes it works great and lasts a long time, and others it ends up being junk, so we'll see.

Thats the one I would go with. I had the other type with the pilot bit and it did not last long.

i used a matco one(40 bucks or so), centerpunched the spot, spun it nice and slow(about 200 rpm or so) and 1 bit got me through everything i needed... and i needed alot...

I've been happy with these. I've cut a LOT of spot welds this winter. I run it off a small cordless variable speed drill. Make sure you start with a good ddeep center punch. if you don't the cutter will wonder and break teeth in an instant. Like the primate said, spin it SLOW. Enjoy

I bought one of the drill bit types from east wood. IT works ok, but what I found works the best is a die grinder. Works ten times faster , much less effort, and allows to get entire spot weld area. Sometimes the spot welds are not concentric so cutting with a cutter can still leave some of the weld, plus if the drill drifts you are still left with welded material.

Sorry bout resurrecting such an old post but I would like to get peoples thoughts and see if opinions have changed in the last 3 1/2 years.

I am ordering up two quarter panels and will be replacing them over the holidays this year, read ALOT of spot welds to drill out as I'm doing full quarters. Obviously I don't want to buy something that will go dull in short time, but also don't expect it to last through two quarter panels, would be nice though. Another question on the cutters similar to drill bits, can they be sharpened? For example using a drill doctor or something else.

Thanks for all the insight.

I have a set of these that I got from a Snap On truck (Blue Point) and they are fantastic but not the cheapest out there. Since they are Blue Point that means Snap On buys them on the oustide and relabels them. Maybe other companies sell the same thing for less.

yep..that's the one

I've purchased the spot weld cutters from Eastwood, Northern Tool, etc. No offense, but they're junk. Don't waste your money. Go here and buy this set. You won't regret it. Main thing to remember, go slow when drilling and let the bit do the work.

I've wasted money on snap-on,hf,junk,the best by far are Blair ,also same kit can be bought from Matco for $50 a kit with 5 or 6 different size bits,it literally takes only few seconds per spot weld

Actually wasn't too impressed with the blair kit. My NAPA kit proved to be a bit better for quite a bit less. The blair was fine for the first 1/2 - 1 dozen cuts, then seemed to dull and didn't cut well at all. I couldn't get through one quarter panel with all three cutters in the kit. Super disappointed! The NAPA cutter worked like a champ though. Did one full quarter and part of the other with one that was used a bit last year. Do know what was up with the Blair, but I wasn't impressed, unfortunately.
