You probably want to squeeze adjacent blanks:
wc FILE | tr -s '[:blank:]' ' ' | cut -d' ' -f2
Note you might wonder why cut doesn't support -d'[:blank:]'
to auto skip runs of horizontal whitespace. Details here:

Note also that wc can output particular counts in isolation.
I.E. this will get the same affect as your original:
wc -w FILE | cut -d' ' -f1
cheers,

I interesting information.
I had exactly been using this as a workaround.
Cheers,
