I have one with an Albrecht chuck on a Royal adapter.
I do not like the Royal adapter. The adapter is assembled with a pin pressed into one side of the shank and then the pin is ground down below the surface. It can not be disassembled. The spring is a little bit too stiff for my liking on very small drills and there is a slight catch in the action just before the full extension is reached. If it could be disassembled it would be easy enough to take care of.
I have used a different adapter in the past that worked very well and could be disassembled to alter to personal preferences but I don't know who made it. Unfortunately it was not mine.
Still, I would not be without the one I have and it works well enough for 0.018 venturi holes that I have been drilling.
