I bought a "Great Neck" Metric tape wrench set, but the wrench does not
grip a 6mm tap securely. The taps all have square ends, but there does
not seem to be anything in the wrench that is designed to mate with that
square end.

The "sure grip" chuck doesn't. Anybody familiar with these tools? Are
they normally OK (at least for occasional use)?

It's hard for me to believe that even the cheapest tap handle in the
world wouldn't be designed to grip the square end. That feature is
pretty fundamental. Do you have prior tapping experience? Do you have a
pic? Pics I found online aren't close-ups of the business end.
