Is it old cast iron or new?
Lenox makes cast iron cutting recip blades but they don't work well at all on brand new stuff. I have had success with them on old pipe but above all I'd rather use a pair of snap cutters where space allows.

I use a el cheapo diamond blade in my 4 1/2" angle grinder, or the thin metal cutting blades. They cut faster, but you will wear them down and need to put a new one on rather quickly.
