I recently bought an ETM ER40 collet setup for my mill. It is a set with a full complement of ER40 collets and R8 holder.
Mark Jacobs gave me some advice on a MT3 shank so I could use them on my lathe as well. There aren't too many MT3 shank options out there for ER40 collets. Mark shared his experience and also gave me some tips on adding a tang on the end so it would not rotate under use in the tail stock of a lathe.
The shank is a Shars and appears to be well made. Add to it a Maritool bearing cap, make a tang and you have what I think is decent tool holder for the tail stock of a lathe. (EDIT: also can use it in my drill press.)
Based on Mark's advice, I made a tang this morning. His coaching was spot on as usual.
