ABSTRACT:
A coring device includes a semi-cylindrical channel with an angled forward end having a cutting edge thereon, with a second semi-cylindrical channel hinged to the cutting channel to pivot between a closed position forming a tube, and an open position permitting the introduction of a driveline between the channels. The second channel is shorter than the first channel, so that the cutting edge of the first channel projects forwardly beyond the second channel.
