Abstract
A core drive for internal drive core cutters having a non-rotating pull rod and a rotating drive plate. The core drive has a rotating element assembly that releasably couples to the drive plate and a non-rotating element assembly that is secured to the pull rod with a quick release securement. The drive is mated with a pusher so that the drive and pusher kit can be interchangeable with kits of other diameters to enable the quick changing of a mandrel to cut a core of a different diameter.
