If you have rigid tapping you should be able to use a ER- style collet. dont use a jacobs chuck as they stuff the shank of the tap (if they slip) and make them un-usable with er style collets(if you have any).
ALSO:
I have never seen a tap collet let alone ever heard of one, i would like to see one though. maybe someone can post a picture of one?
On the other hand, You have different fingers.
