I used the same sawzall and cut through copper and EMT electrical

I have had good success cutting new cast iron DWV using a Lennox
reciprocating saw blade marked 800RG, "Medium Carbide Grit Tile, Clay
& Pipe". Took me a minute or two to cut through 2" CI with low to
moderate pressure.


I think 'low to moderate pressure' bears repeating. It is
instinctive to add pressure when things aren't cutting- but light
pressure and pipe cutting oil are your friends.
