My Dremel (model 398) has a jammed front bearing probably due to too much dry wall cutting and not enough cleaning. I was shocked happy when I found several of those bearings (used) in my toolbox.
help] (Dremel 4000) I need to replace this bearing(B) but can't find a way to remove. Pen is pointing to the only place where there is a joint between axles. : r/Machinists
