This is a picture of two old galvanized water supply pipes found inside my garage wall cavity. Abandoned for a long time, I think they were original 1941 pipes when the house was built.
The pipes, one 3/4" and one 1/2", come in from the crawlspace through two holes through the 2X10 rim joists, they then turned up another 4' or so inside the wall cavity, but I cut the risers back to the elbow.
I am planning to use this stud bay and these pipes are in the way so I like to get rid of them (I mean without moving 40' through the crawlspace to cut them from the other side). There is an elbow only a few inches on the other side of the 2X to turn the pipes down. So my first try is to use a pipe wrench to rotate both pipes out of the elbow. No good. I squirted some WD40 and let it soaked, no difference.
My next attempt will be to cut them. I tried a sawzall but the angle is awkward with the blade kind of bent but I have the front of the wall blocked by a 1X8 board it's difficult.
I doubt an OMT will be able to cut through this just oscillating through thick metal.
Will a dremel work or will it burn up after a while?

cut the risers you removed so they just fit vertically in the space.
screw them into the elbows and use them to unscrew the pieces.
hopefully you get lucky and the pieces unscrew

I think your oscillating tool may work with a carbide blade or maybe a cheater on the pipe wrench I’m surprised the piping did not break while using the pipe wrench

My choices in this order are 1) loooong pipe on the pipe wrench handle, sometimes you need 3 or 4 FEET of leverage, my bet is that those pipes will unthread. Challenge is that you may not have room to swing the long handle. Option 2 would be angle grinder with cut off wheel. Will make sparks but should be easy to contain there. I love my portable band saw but not sure if have room to get it in there for a flush cut.

I've made that cut in galvanized with both an angle grinder and an oscillating tool. You just need the right blade, and you will probably need to replace it after. The angle grinder is faster if it fits in there.
