PERFORA'CULUM. An instrument employed by carpenters, carvers in wood, and artizans of a similar class; usually translated a gimlet or auger; but it is clearly distinguished from the terebra in the following passage, where its connexion with the word dolatus would seem to indicate some implement more in the nature of a gouge — perforaculis dolatum, terebrarum vertigine excavatum. Arnob. vi. 200.
