A tube cutter doesn`t cut metal - it DISPLACES it. Which means that the outside diameter within 2 to 3 mmof the `cut` areas will be too large for the stem to go onto, and the inside dia will be too deformed and small to insert a star-nut.

Of course if you insist you can always check and see for yourself!
