Query: wobbling chuck

i purchased this drill in december. after using it for a week i noticed that the chuck wobbles slightly. i returned it for a replacement. it also wobbles. if you use a long bit in it the wobble is significant. once the bit drills into your workpiece, the wobble transfers from the bit to the drill and your hands. i've e-mailed bosch twice about the problem without ever getting a competent reply. i'll get the milwakee.
