I have a panasonic ey6405 12 volt cordless drill and it's great. However, one of the
three "teeth" in the chuck that hold bits,etc has somehow become shorter than the
other two and now drill bits apexes, etc wobble. The tooth isn't not broken off, it
just doesn't extend far ernough out whem the chuck is tightened. I took the chuck
off, but got nowhere. I oiled it, tapped it etc. to no avail. Any ideas on what
hapopened or if it can be fixed. I don't mind buying a new chuck because I like the
drill, but I'd like to give fixing it a try first.
