removing burrs from drill bit shafts?

Drill chucks generally have three pieces that clamp down on the drill bits.  It sometimes happens that the bit slips just a bit while the drill is being driven into metal or sometimes even hard wood, and the chuck pieces raise a burr on the shaft.  I am not certain that the nomenclature that I have used is precisely correct.  But you know what I mean.  If I use a drill bit gauge, the shaft will not fit into the proper hole, because it is no longer fully round the entire length of the shaft.  I have usually tried to smooth out the burr with a whetstone or maybe a fine file.  if the burr is really bad, I may use a grinding wheel.   I have to know if there is a better way to remove the metal that causes the shaft to sometimes not settle properly into the chuck later on, and even cause a bit of wobble.
