MY "new" to me VMC came with a erickson cv40tgf531 tap head.

Floating or tension/ compression which ever....

No luck on google to figure out the collet thing.....no collets with it.....

Well, the TG part of the name suggests that it likely takes a TG family collet. (75/100)
However - the nut and threads look more like that for a large DA collet. (180/400)

But it very well could take a "Tap Specific" collet as well - or maybe even more likely?

But - our being able to look down into the nut as well as the inside and threads of the receiving end would be helpfull.

Have you taken any measurements to find out what the taper and size is?
