Pin Block Drilling

I've found it use ful to set up a vacuum hose next to the drill bit.  I
provides a steady stream of air, (it must be very close), and cleans up
instantly.  Kinda noisy, but that's what ear plugs are for.  I shape a
piece of aluminum, attach it to the hose, and suspend it close so it
pulls air the length of the drill bit.  Then, I take my time between
drillings to let the bit cool in the air rush.  A project not to be
hurried.
