Some machinists think there's a difference between making holes with the
work rotating and the bit steady (boring) and the bit rotating and the
work steady (drilling). I don't know why other than boring is better for
making large holes. Anyone?

I know it works from the days before plywood when I nailed #3 sheeting
on roofs, but I don't know why dulling the tip of a nail helps to make
it go straight and not split the lumber. Somebody?
