Many years ago in the dim & distant past I remember using a product
called Lubra Sheet for drilling multilayers. It was a thin sheet of
material which was placed on the bottom (or was it the top?) of a stack
of multilayers. When the stack was drilled the idea was that the Lubra
Sheet lubricated the drill and improved the drilled hole.

Is this product still available? Has anybody got experience of using it?
