Did some minor searching and ETCO is Engineering Tooling Corp., "Quality Tools and Inserts for Swiss Style CNC Screw Machines"
A couple of the tool holders shown on their home page seem to hold these inserts, just not at the 90 degree angle of the one on ebay.
The screw machine world is a bit of mystery to me. I suspect they buy the "micro inserts" ready ground, and being small, they are cheaper.
I suspect it would be too much of a project to make a similar tool holder for the home shop and use small HSS tool bits.

Subject: [7x12minilathe] Anybody know what this is?
Howdy gang:
I've come across an interesting looking, alternative tool post on
ebay, of the likes I've never seen before.
The seller does not mentio what advantage it has over thet nomral type
tool post. The photo is quite poor, and the seller further seems more
interested in terms of payment.
Looking beyond all this, though, might anybody here know what the
application is for this type of toolpost?
Thanks, Mark
