Wire-line drill tools can lift drill core from drill rods without picking up bit. All the tools include principal parts of the drill tools, overshot assembly, drill rods, winches, hoisting, circle wrench and etc. Their advantages are higher penetration, higher core recovery ratio, longer bit life and lower labor intensity, and the advantages get more clear with the increasing of hole depth.
