Abstract

600327 Disclosed is a drilling head assembly (200) particularly for use in wireline drill assemblies for sonic drilling processes. The assembly (200) has a body (220); a spearhead (240) operatively associated with the body (220) and configured to translate axially relative to the body (220); and at least two latches (260) operatively associated with the spearhead (240) and the body (220). The at least two latches (260) are configured to move between an extended position and a retracted position relative to the body (220) in response to axial translation of the spearhead (240) relative to the body (220). In an extended position, the at least two latches (260) cover more than 25% of the circumference of the body (220) adjacent the latches (260).
