Abstract

A tool holder (2) for a powered hammer comprising a tube-like tool holder body (66) which has a forward end for non-rotatably receiving a hexagonally cross-sectioned shank (3) of a hex-shanked tool. The forward ha an axially extending slot (10). A locking body (54) extends through the slot and is moveable between a radially inward locked position in which it engages an axial closed groove (88) in the tool and a radially outward release position. A locking member (52) and associated sleeve (50) are manually axially slidable to move locking body (54) between the locked and release positions. Should the tool be inserted in an incorrect orientation, the locking body (54) is trapped by the shank (3) of the tool in its release to its locked position. This provides a clear visual indication that the tool has been inserted incorrectly.
