Cutting Speedfit plastic pipe with Rothenberg Copper pipe cutter?

I've certainly used copper cutters for plastic pipe and the only issue I've had is that it compresses the cut pipe end inwards making fitting the support sleeve a bit more tricky - but not much.

One thing I'd add is to check the surface of a good half-inch of the pipe end after it's been cut (do a test cut) to see if the wheels have scored the pipe surface at all. If it has, then be very wary because the push-fits rely on an O ring to make a seal, so any significant scoring could cause leaks.

Chances are it'll be ok.

 

If it cuts it cleanly enough, and if the end half-inch outer surface is undamaged, then it's ok

 

Just buy the proper tool, even a cheap one is better than a copper pipe cutter.

If you haven't lots to do, these will do you.

Why on earth would you risk it?
Go buy the proper tool for the job

 

How many pipes are you planning on joining?
Two, six? A thousand?
If the former just cut the buggers and get done what you need to get done, ie listen to, DA, it'll be fine
If you don't you'll be spending hundreds of pounds on rothenberger superfire super-duper soldering torches, pressure test equipment and a weeks training course in how to effectively complete the simplest of plumbing tasks.
Use a hacksaw if you need to and carefully be-bur the edges if need be.
You're over thinking it.

 

I have had a top of the range underfloor heating system delivered complete with cutters for the plastic pipes. The cutter was a set of Gardening Secateurs !

As for using the copper pipe cutters - don't chance it. And never use a hacksaw.

 

Quickest way to damage O ring is using hacksaw & deburring of edges pipe it is still rough enough to damage fitting.

 

Wonderful - here we are - a plumbers forum - and recommending people to cut plastic pipe with a hacksaw. Are we serious...
It matters not if you have 1 or a 1000 joints to fit, just the one joint failing can cause thousands £ in grief.

Go get the proper tools, there are no short cuts in plumbing

 

There is only one recommending that and it was soon countered with the instructions:

 

If you're a bit restricted for space and can't get a hacksaw in, you could use a drywall saw instead.
