Rent a "snap-cutter" for CI pipe.
If that's not practical for a one-time, I would go for the abrasive
saw blade. Depends if you can get the saw all the way around.
Sawzall works with a good blade *sometimes*. CI is quite variable;
some will cut like butter, others are extra hard and eats blades
Or....do like the old timers: gently make a groove all the way
around the pipe with a chisel, then break it apart:-)
If you use an abrasive saw, wear a good dust mask.
It has a chain and wheels where the rolling links would be these score
the pipe but you don't ahve to go all the way around like a tubing
cutter you only have to go back and forth a few degrees and then
tighten some more and repeat until you hear SNAP, you won't miss the
snap, so wear two pair of underware that day and make the oldest pair
the first you put on!! LOL
Good luck, Rich
The last time I went to the rental centers for a snap cutter they looked at
me like I was crazy.
Modern sawsall blade technology has made this item a non stock in my area.
Go to a plumbing supply house and buy the right blade for your sawsall.
I think it has 6 teeth per inch. It is not carbide or ceramic. Looks like a
coarse wood blade but it does the job.
I tried a sawsall once, and it did cut, but real slow, and tore up the
blade pretty fast. I gave up on the sawsall, grabbed my angle grinder
and it went right thru real fast. Use the THIN cutting wheels, not
the thick grinding wheels. Be sure to cut all the way around. but you
do not have to cut all the way thru. Then snap it with a hammer.
One cheap angle grinder wheel should cut it.
