Abstract
A drill assembly or auger for forming a hole in a surface such as ice and having a readily extendible and retractable shank assembly. The shank assembly has first and second longitudinal shank members. One shank member is telescopically engagable in the other shank member and moveable between a first relatively retracted configuration of the shank assembly and a second relatively extended configuration of the shank assembly. First and second coupling members are located at longitudinally spaced intervals on said shank assembly for coupling the shank member having cutting means to the shank member with operating structure upon operation of the operating structure to rotate the shank assembly in a direction to form a hole selectively in the first and second positions respectively. The coupling members are releasable for telescopic movement of the shank members between positions by rotation of the shank member having the operating structure in a direction opposite that necessary to form a hole.
