Abstract: PURPOSE:To enable a core drill to fulfill a stable function for a long period by withdrawing the core drill, leaving a cut lump in the core body after drilling a large bore hole in a concrete material or the like and permitting the cut lump to be simply taken out of the core body. CONSTITUTION:Respective projections 9 of a coupling ring 7 of a core drill are fitted loosely on a tubular part 3 of a top board 1 through the central part of a inclined surface 4 provided on said tubular part 3.

Abstract: PURPOSE:To simplify the structure and facilitate manufacturing, and to ensure the connection hard to be coming-off in terms of structural bonding power, when a chain or a rope is used for the connection by arranging an elastic member on a notch part of a letter C-shaped hook. CONSTITUTION:An elastic member 3 is arranged on the notch part of a letter C-shaped hook 2.
