I agree with Dan390- the key is the Operator.  I bought the Blair cutters and would burn them up after 5 spot welds.  I didn't know what I was doing and it dulled/broke them very quickly.  I finally figured it out now they last for many spot welds. Let the tool do the work and don't force it.

Most failures with spot weld cutters are "Operator failure" basically if you do it wrong it will shatter or eat the teeth right off, most people just think these will zing right through in an instant no problem.

No two spot welds are alike and none are perfectly flat around the weld. If you just hit it like a monkey at full speed and force, you'll be buying 5 gallon buckets of replacement cutters. Do it right, and like others have said you can make a good head last literally years.

I like to start above the highest point of surrounding metal at a low RPM, let the teeth lightly start to dig in and cut a circle outline, slowly applying downward pressure until you see a full circle.

If it constantly wanders off the weld and is getting frustrating, drill a small center hole so the spot weld cutter center guide pin will engage that hole, that should help. And that little hole is easy to weld up when you put the patch on later.

Then you can speed up and apply pressure, but remember you are only trying to cut through the outer layer of metal, and once cut it leaves the center nugget (the weld) behind.

That way you later grind the nugget smooth and you have a 100% solid inner panel to weld the new patch to, instead of filling holes like if you just drilled through the spots with a drill bit.

Patience and looking at what's happing while you do it is really the key to making ANY cutter work.

I found that drilling a pilot with a small centering bit first works the best to keep it from walking around. It makes the process much easier and cleaner. Also less frustrating. I had 2 drills so I didn't have to switch back and forth. I also ground the paint down so I could see the center of the weld first. I drilled a lot of welds out fixing my 71.
