Abstract

See full text

A shank attachment device attaches a core drill to a rotating portion of a drill device and includes an arbor and a shank. The arbor is detachably attachable to the rotating portion. The arbor and the shank are detachably attachable to each other. The shank is detachably attachable to the core drill. A stopper engages a groove of the shank to stop a movement of the shank in an axial direction away from the arbor. A rotational torque of the arbor can be transmitted to the shank by engaging a first engaging portion of the arbor with a first engaged portion of the shank. The shank contacts the arbor to stop the movement of the shank in the axial direction toward the arbor.
