Excessive drill run out in your Ellis Power Tool can be caused by a bent drill, which requires replacement. Another cause can be chuck jaws not clamping evenly, in this case you should install the drill correctly. Worn spindle bearings can also cause run out, so you may need to replace the ball bearings.
