I have not seen plastic pipe cutters with wheels. I use the ratchet type (Ridgid) but only for 2" and below. Since i don't use the larger pipe much, I have a handsaw for cutting. Going by the numbers, I would agree that the one you mentioned would cut 6" pipe.
If you have never made a mistake, you probably haven't done much.
i use a combo of cutters, chop saw for rough ins and top outs. recip saw for small jobs, ratchet cutter for small pipe and a rigid cutter with pvc blade for finish work( less mess to clean up and more precise) never use hack saw though thats for non plumbers lol
anyone try the Milwaukee M12 PVC Cutter and if so what have you thought of it? I have one but the jury is still out on how well it works
On short pieces it will explode the pipe.
Longer pieces it works OK but takes practice to get a good square cut
