Welcome to the forum. I'd try contacting Bosch. Sounds like a really techy specialist question to me.

Yeah when I took my turning class last winter the guy teaching had one in the shop. He swore by it. Also had a really expensiveness 8" grinder by the the Rikon is supposed to be really good too!
Great job guys! This is a really sweet drill and I know (not me anymore) a lot of guys will be looking forward to it coming here! I sold all of my 18v Bosch stuff and now am running Dewalt but Bosch makes high end tools and this shows it.
