  That's probably because you haven't the right cutting shape to your
drill :)
  For thin sheet (as PCB) drilling it must be different than a normal

(or PCB) sheet surface.
  When I was a young boy, at some practical clases, a good sharpened
drill was marked always with an "A" by my old teacher ... :)
