Another machinist told me he'd heard that someone is making an ER collet version of the Brookfield style tool holders, but he didn't recall the manufacturer. Anyone know who this is?

No as I said a Brookfield style holder as far as adjustment goes, but instead of using V blocks to clamp the drill uses and ER32 collet.

Ah so. IOW - still has the 'floating' adjustment feature between ER-system and arse-end?
TG system might be another one to search on, then. Seems to score more 'wins' over ER where seriously firm grip is on the menu.
That said, seems to me the Vee-block would be the more useful where tool shank was other-than round, on-centre or otherwise.

I changed the V holders for small ER11 collect chucks.
Also bought an ER25 round disk chuck, that can be used on rotary table with the intention of milling it down to fit on the V holders.

Have a few, one similar to the old Archer type, friction disk.
Another where there is a small plug inside with a slot that pulls forward off a cross pin to make it freewheel at end of stroke.
The there is the one that pulls forward off two pins to release the drive.
Had four of these Model L's until I bought the turning centre.
Bought New and reconditioned from Bracehand in the 1980's
