Years ago I was running a batch of grip frames on a drill press. Simple clamp in fixture just left the spindle running when changing between frames. As I was pulling one frame out the chuck fell off the arbor and hit me in the back of the hand. I was wearing nitriles at the time to keep the coolant off of me and the bit wound itself up in the glove as it fell. You can imagine what was going through my head when I jerked my hand back and from the looks of things had a chuck and bit sticking out the back of it. Luckily it just barely nicked me and was simply stuck in the nitrile glove not my hand.
While I'd like to be able to justify spending the money on a quality chuck and arbor the machine doesn't see the use to warrant it hence my wondering if one taper had a better reputation than others.
