Abstract
The present invention is directed to a coring drill and method for preparing a block for containing a receptacle assembly. The coring drill comprises a generally cylindrically-shaped corer hub having a longitudinal drilling axis. A generally cylindrically-shaped first corer has a first-corer axis coaxial with the longitudinal drilling axis and a first coring end having a first-coring diameter. The first-corer is removably attachable to the corer hub. A generally cylindrical-shaped second corer has an second-corer axis coaxial with the longitudinal drilling axis and a second coring end having a second coring diameter greater than the first coring diameter. The second-corer is attached to the corer hub. A generally cylindrical-shaped counter-borer has a counter-borer axis coaxial with the longitudinal drilling axis and a counter-boring end having a third coring diameter greater than the second coring diameter. The counter-borer is attached to the corer hub.
