The light moves with the quill and so doesn't block it. I've tried it with a short 3mm slot drill and it worked a dream, gets even better with longer bits.

The aluminium foil around the inside of the shade should reflect quite a lot of light and extend the size of the light - the light is very even on the table and on the drill bit
