Would this be suitable to cut my steerer tube?

Will do, I'm going to assemble it all, mark it, take it apart then cut.

Best advice is measure twice and cut once.

I would like to repeat that tool is really not designed to cut steel, it may do it, but it is 100% not designed for that. It is designed for cutting copper tubing.

Fine toothed hacksaw every time.

On another thread, I have said I have become reluctant to give advice.

However, as I am such a nice person , here's some advice about cutting the steerer.

"Do not cut it until you are 100%, definitely, absolutely SURE you are happy with the stem height".

Cut it too short and then find the H/bars a little low, you will need a 'raiser/angled' stem.

When I say this, I mean "Have you ridden the bike for 12 months with the stem in a position that you 'would not change'"?

Wrap a sheet of paper around the tube - line up the overlap and you have a perfect 90 degree line. You can mark it out from this - I butt a piece of masking tape up to the paper to give me a line to cut to.
