ABSTRACT:
An apparatus for obtaining a core sample includes an elongate guide pin and a hollow drill element. The drill element has an open front end provided with a cutting edge and an open rear end provided with an axial engagement structure for engaging an associated driving tool. A longitudinal aperture extends from the front end of the drill element to the rear end with the aperture having a smooth uninterrupted interior periphery throughout at least a major portion of its length. A spacer slug is adapted to be positioned in the drill element longitudinal aperture. The spacer slug has a centrally disposed aperture extending longitudinally therethrough and sized so that the guide pin can extend therethrough. The spacer slug has a suitable outer diameter so that it can slide in the drill element longitudinal aperture.
