Spot Weld Chisel - any recommendations?

[wazzabie]

What do you use for a spot weld chisel?

 

[sevt_chevelle]

None you either grind or drill them out. A chisel imo is sure fire way of destroying the underlying panel.

 

[Tinner]

Drilling usually works best. However, if you miss a bit with the drill, or on thicker materials these work.

I've had them for years. Some spot welds pop pretty easy, some don't.

Don’t they make a special drill bit for those things. I never did many over the years but for occasional use an appropriately sized regular bit worked well. With a chisel method I’d be more worried about bending or distorting the panels .

You can find a special bit called a spot weld cutter. Just find one the same diameter as the welds, and you’re good to go.

A spot weld chisel is actually to be used after drilling the spot weld since you won’t get the entire weld sometimes. They’re called a spot weld chisel but they’re more of panel separator. I use a Steck after I’ve drilled the spots to help split the seam.

this, might be useful for very tiny welds that left over or missed.

I use these after i drill the weld. Also use them in a pinch if for some reason I cannot drill the weld. When they get wore out the snap on man warranties them.

Streck seam buster and Blair rotabroach are my go to tools for spot weld removal.

Spot weld drill bits like this are what you seek. 8 and 10mm for automotive, mostly 8mm.

After spot drilling thru the top I just use a 3 in 1 painters good to separate the panels

Whalebone. If you can find one, will split a spot weld like butter.

I use a Starrett automatic center punch to keep the #40 wire gage drill bit centered. Then afterwards I use a larger size drill bit to separate the two sheets of sheet metal.

Pairing up Blair Spot Weld Cutter with a Streck Seam Buster my son and I removed over 100 spot welds from a 1970 Nova during a full restoration. We had little to no damage to the underlying panels once we mastered the process.

The chisel is sharp on the front and right curved portion. It can be struck from the rear or the flat left side.

Both are available on Amazon.

I'll second the Steck chisel. I have their Seambuster version that goes in an air hammer. It's great, if noisy. Be sure you have the spot welds drilled correctly, as you can start damaging sheet metal pretty quickly with this think if you don't pay attention.

Is the Steck Seam Buster thinner than something like the Mayhew Dominator Weld Wakker? The blade on the Weld Wakker is about 3mm thick. I wonder if it will be hard to wedge between seams.

I have mixed success with chisels. Equally, I have had mixed success with special spotweld drills. I think the chisel and spotweld drills work well together. Don't rush it.
You will never disappointed with MAYHEW. Buy the best drills.
BE AS GENTILE AS YOU CAN.

Vim makes a set of striking scrapers that is similar to the Snap On above; but I think that they are even thicker than the Mayhew splitters. I bought the Mayhew, but they are sharpened on both sides, like a traditional chisel. I ended up just using an old paint scraper since it was much thinner. The Steck looks like it's only sharpened on one side? Anything that's going to stand up to moderate use is going to be ~3mm or thicker. If you do a good job drilling, a thin paint scraper with the steel thru the handle will work.

Yes, it is thinner than the Weld Wakkers. It also has a more shallow bevel ground from only one side which helps control which panel gets wrinkled and which panel remains true. I have Weld Wakkers and they are not as useful for this application because they are so thick, and the blade is relatively blunt, you typically make a mess of both panels. I also have the Snap-on strike through shown in the posts above, and even a PB Swiss thin chisel but they're all too thick to work effectively for separating autobody panels.

I have Lisle and Steck, both are great.

Somewhat related, I have found that belt sanders (Dynafile, 3M, or even the cheap ones) are faster than drilling. Blair spot weld cutters are the best if you're drilling.

What speed do you run the spot weld drills ?
