An impact tool (10) useful for performing a number of different surgical and industrial functions is provided. The invented tool can perform such surgical functions as freeing cement, implanting pins, and setting guides and industrial functions such as installing various fasteners. The tool comprises a body having a quick disconnect assembly (18) coupled to a second (20) end for quickly attaching and detaching different desired surgical and industrial implements to the tool. The quick disconnect assembly communicates with an impact inducing assembly (41) that is retained in a channel (24) in the body. The impact inducing assembly causes an implement retained in the quick disconnect assembly to deliver an impact with a calibrated force to a desired object. The orientation of the components of the impact inducing assembly can be inverted so that the tool is actuated to apply an instantaneous extraction force to the desired fastener or surgical aid. In the alternative embodiment, the user draws the tool away from an object secured to the quick disconnect assembly until the impact inducing assembly disengages the quick disconnect assembly to impel the implement along the channel for delivering an instantaneous extraction force to the desired object, for at least partially withdrawing a portion of the object from a surface in which the object is embedded. An antirotation assembly may be provided.
