having used diamond to cut ferrous, I found it almost useless. I was
told the diamonds react with the iron and dissolve into it, making
diamond discs ineffective on iron and steel. And in fact, hardening the
steel a bit in the process.

I have a diamond disc (Screwfix 71994) which is going strong after almost
a year say one job (some big some small per week average). I know it cuts
through CI. If there is something better let me know but I know it is a
lot better than ordinary resin/abrasive cutting discs.
