Getting spot welds out?

[Blue71]

I am in the process of doing door posts, rockers, inner fenders, etc. Is there an easier way to get the spot welds out, other than a good metal drill bit? I have heard of a spot weld remover. Has anyone used one? Where can I get one? I keep dulling the good drill bits and the $$$ are adding up ever time I have to get a new one. Is there another method that is easier and less time consuming.

Thanks Much,

Think they call it a spot weld cutter. Look at you local auto body/auto paint store.

There was another post on this within the last week with a lot of info to help you out. If you have a cut off wheel on a die grinder, use the edge of the wheel to grind right on the weld itself . Just rub it back and forth over the weld they go away pretty fast this way. Look for the other thread.

I mainly use a Roto-Broach spot weld cutter. Don't try and make do with the cheap ones, they will only frustrate you.

I haven't ever used one but Eastwood Tools carries a few:

I also couldn't tell you if these fall into the "cheap" catagory, but maybe someone else can. I've had good luck with the 1 or 2 tools I've ordered from Eastwood.

Napa has a spot weld cutter part # NBK 770-3841. It looks exactly like the one from eastwood. Cost me $11.89. Blade is still sharp after using it to remove my door post.

I used a Eastwood spot weld bit and it lasted just long enough to remove the spot welds on the windshield side of the hinge. I had to use a drill bit to do the other side. It dulled up quick. Whenit was new it worked great for the first half of the welds. I would defenitly spend the extra money and buy something good.

You might already be doing this, but just in case. When you are using the spot weld bit or just a regular drill bit, use a controlled speed and a mild amount of pressure. It also helps drill bit longevity to squirt a little oil on the weld while you are drilling it out. It helps keep it cool. If you apply too much pressure and use higher drill speeds it will just eat the edge right off the bit.

Of course, which is more valuable to you.....The time you will waste by taking it slow on all of your spot welds, or the money you will spend on a box of bits.

I have both sizes from eastwood, for the bronco you want the big one since some of the welds are not as they seem. I have had good luck with them, two weekends ago i cut almost 300 spot welds on the body. It got a little dull about half way so i just touched the cutting edges up a little with the dremel tool and kept going.
