A Vintage Flexible Drive Shaft Tool Attachment with Three-Jaw Chuck

A vintage workshop flexible drive shaft attachment designed to extend the reach of a power drill or bench motor for precision tasks. The tool consists of a flexible cable housed within a black protective sheath, featuring coiled steel spring strain reliefs at each end. One extremity is fitted with a small, knurled three-jaw drill chuck for securing small bits or burrs. The opposite end features a straight steel drive shank intended for mounting into a drill chuck or motor coupling. This drive end is housed in a knurled metal sleeve that incorporates a grease nipple for lubrication of the internal shaft. An L-shaped metal locking pin is attached to the cable via a spring-clip loop. No maker marks or stamps are visible on the item.
