Abstract
To provide a drill cover and core drill unit that improve safety and suppress a decrease in work efficiency. [Solution] The drill cover 20 comprises a cylindrical support portion 21 that is attached to the drill head 2a, and a cylindrical cover portion 22 that is movably supported on the support portion 21 along the axial direction of the support portion 21. When the cover portion 22 is overlapping the support portion 21, it exposes the connecting portion 5. When the cover portion 22 is pulled out from the support portion 21 toward the opposite side of the drill head 2a, it covers the radially outer side of the connecting portion 5.
