i bought this from a salvage place . after i cleaned it up it seems to work ok BUT
what sort of chuck is used to hold thread taps
the collar sitting next to it appears to hold a 1 inch thread die
any idea what brand name is

Mine has a 4 jaw chuck similar to a conventional tap wrench.
No idea for the brand of yours

would a drill chuck adapeted to fit be strong enough

Drill chuck has 4 jaws normally, tap has 4 flats. No way will a drill chuck hold a tap in a tapping adaptor with the chuck jaws on the tap shank.

The ones I have used have had a resilient collet system to centre and retain the tap and a smalll self centering clamp/dog system to drive the tap. This style.
