When drilling holes 48” long for floor lamps I use gun barrel drill bits that are hollow so coolant and lubricant can be pumped through them but instead use compressed air to blow the chips outI've never used the Woodcut but as for keeping chips clear, I wonder if the same thing I use when drilling deep holes with a Forstner bit would work: I have a thin nozzle on my air line and while drilling I direct a constant stream of air into the hole behind the bit. This not only blows out all the chips as they are created, but keeps the bit a little cooler. Would that work in the groove when coring?
