Abstract

See full text

A notch-forming extraction tool for helically coiled wire inserts according to the invention includes a mandrel with a second end having a tooth adapted to form and be received by a notch of the insert. A first end opposite the second end is received in a bushing of a handle portion for connecting the mandrel to the handle. Left-hand rotation of the handle contracts the insert about the second end of the mandrel to facilitate removal of the insert.
