I found some old iron pipes that had been left rolling on my dining
room ceiling by a previous plumber. They are far too long to get out
without cutting them or taking up all the floorboards.

I have tried a metal cutting blade on my jigsaw but progress is
*extremely* slow - the pipes are thick walled and very hard.

Will an angle grinder with appropriate cutting disk do the job...I
don't actually have an angle grinder otherwise I'd try it. (I've never
used one before)

TIA
