Abstract

A replacement tool handle for a percussive tool includes a high strength, load-bearing rod which is inserted through the eyehole of a tool head from its upper end, a grip which ensheathes a portion of the rod projecting from a lower end of the tool head, and two interlocking members which fasten the grip to the rod. The rod includes a handle shaft capable of passing completely through the eyehole of the tool head, and a shaft retainer located at a first end of the shaft for preventing an adjacent end of the rod from passing through the eyehole. The shaft retainer forms a generally frusto-conical slug having an outer surface portion generally corresponding to a portion of the eyehole, an enlarged portion which is incapable of passing through the eyehole, and an inner cavity in which the first end of the shaft is secured. Both the handle shaft and an internal cavity provided the grip have non-circular cross-sections to prevent turning of the grip relative to the shaft. The interlocking members each include tooth portions which engage one another within the outer periphery of the handle in a manner which denies access to a user, thus ensuring a permanent connection.
