   Patto, check knots archives if I recall, they're were many posts in that thread.

   I suspect the chuck or chuck jaws

    The chuck is attached by a twist fit taper in a tapered hole

   Some times it's only a bit of dirt in the taper,  so that's the first thing to check also, use a piece of ground drill rod in the chuck to check for runout

    Believe it or not, most drill bits are suspect . A good Jacobs Chuck will last you forever. Avoid imports  The best Jocobs are ball bearing chucks

   I'm not sure if this will be of any help but I have an old Atlus drill press with the same problem and the culprit for me is a bent arbor. An easy way to tell if thats the problem is placing a travel indicator on the arbor and turning it slowly.. Needle doesent move? try it on the chuck.. still no movement? then move to the drill rod as suggested before and you'll know which component is causing the runout.
