Raising the bed while running is dangerous. Doing it stopped & restarting may move the work piece.

I make 7” pipes and drill the stems 3/16” in two steps. First is in the drill press for the first 3” and then clamp and use an ‘aircraft drill’ in a hand power drill for the rest. And yes, the aircraft drills wander about 5% of the time.
