<p>An anti-rebound hammer head (1) comprises two body parts (6) each partly hollow and of metallic material and each having at one end an impact face (8) and at the opposite end a sealing face. The sealing faces are welded together so that the hollows communicate to form a single hollow 2, preferably extending more than two thirds of the distance between the impact faces, and containing anti-rebound filling material (3). A neck portion (7) of the parts adjacent the sealing surfaces define an annular recess into which is moulded an annular part (5) of a handle (4). A threaded plug (11) extends into the recess and thus into the handle to stiffen the connection and prevent relative rotation. The construction of the hammer-head is simple and by increasing the size of the hollow (2), compared with known systems, sufficient filling material (3) can be incorporated to allow the impact faces of the hammer to be made of metallic material. The sealing faces may be shaped or bevelled to determine interconnection in one relative angular position only. <IMAGE></p> |
