Any tips for cutting cast iron pipe?

I have been at my 4" cast iron pipe with my sawzall and not making much progress. I'm using a Dewalt metal cutting blade. Is there something better that I should be using or does it just take a day to do it?

wrong blade

Go to a plumbing supply and pick up an eight inch carboloid blade. It takes about three minutes on four inch pipe
Good luck

Wink

Most rental stores have a chain cutter to use to cut the cast iron pipe

A thin, high-speed abrasive cutting disc works pretty well. If you don't mind destroying the pipe then a BIG hammer will also work.

You must have a very dull blade or a DeWalt fake or your angle to the dangle is incorrect. I have cut a few and I have a cheap sawzall, however, one cut one blade. Good luck and have a nice day. Geo

Cast iron

Agree with furd. If you have 4 1/2in. grinder get a cut-off disc, that will only work if you can get all around the pipe. A standard sawzall blade thats not making any progress is usually a waste of time. You can also buy a blade thats designed for cast iron, [plumbing supply]. Lots of luck.
