Title says it all. I need an ER adapter with a 1/2" straight shank so I can improve the functionality of my common router, which only has two collets. Anybody have experience with something like this? All I can find on the googley machine is a bunch of MT2 and 3/4" shanked ER holders. My only other option right now is to turn one down on the lathe at work.

I definitely do not want to mess around with split bushings!

This search, 'er20 collet chuck straight shank', on Aliexpress will return many options if you can use metric shanks.
