Angular contacts will have a fraction of the drag at the same preload. Point contact vs. line contact. My guess is that if a couple of tapered roller bearings were used in a spindle driven by a Dremel, there would not be enough power to overcome the drag if the tapered rollers were even slightly preloaded.
