As long as you ream it after the cutting it is fine to use a tubing cutter.
Anytime we have a pipe threading machine on the job we use pipe cutters, of couse that is for RMC but the rules are the same for EMT.
ARTICLE 358 Electrical Metallic Tubing: Type EMT
358.28 Reaming and Threading.
(A) Reaming. All cut ends of EMT shall be reamed or otherwise finished to remove rough edges.
ARTICLE 344 Rigid Metal Conduit: Type RMC
344.28 Reaming and Threading.
All cut ends shall be reamed or otherwise finished to remove rough edges. Where conduit is threaded in the field, a standard cutting die with a 1 in 16 taper (3/4-in. taper per foot) shall be used.
