What does everyone use to remove spot welds?

Thanks!

those are cheap and guaranteed to break,especially since the spot weld hardens the metal
spend $20 and get a real one.

I bought one of these: http://www.amazon.com/gp/product/B008KFGR2M/?tag=atomicindus08-20
The double ended version would be a better deal http://www.amazon.com/dp/B008KFGR2C/?tag=atomicindus08-20

Its worked fine so far, but I've only drilled out maybe 2 dozen welds so I cant speak to how long it'll last.

Depends on the location and what piece I am keeping.
I either use a cut off wheel, a die grinder, a drill bit or a Blair rotobroach spot weld cutter ( these things are the shiznet )

I've got the Blair cutters and i also have a couple of Harbor Freight cutters. I have used the H/F ones more and they have cut a lot of spot welds... Good buy for the money in my book.

lots of good info^^^^

I use the blair personally and have been doing so professionally for over 10 years. I used to use the drill bit style but when i borrowed these roto broach style, i fell in love and haven't looked back.

Depending on what it is and what I want to save as well as how I am planning to put it back together...
I use a spot weld cutter, like you showed
Or I use a die grinder with a 3/8th solid carbide ball on it. Run it around on the spot weld till the area around the spot weld shows a little blue ring and it's ready to break the remaining metal around the weld

these are available in different sizes but the 5/16 works for most newer spotwelds.
I also use the old black and decker titanuim coated bullet bits for larger ones shown here are the 3/8 and 1/2 inch. Of course no good shop is complete without a couple good spot welders to put it all back together.

winzer makes good bits for cheap.i usually grind them unless i have to save the mating surface then its drill time lol.look into getting some good drill bit lube like boron butter or even rotobroach stick lube
