The invention involves the extraction process of a glow plug pencil (23) or a broken pencil (23) which is stuck in a cylinder head (13) housing (11) of a glow plug engine comprising a lower (19) and upper (17) part, so that the upper part (17) forms a shoulder (21) with the lower part (19), the pencil (23) being stuck in the lower part (19). The process is remarkable in that it includes a step (a) for drilling a bore in the pencil (23) according to the longitudinal direction of the latter which is performed with the use of a drill bit (1) comprising a drilling part (5) with flutes (7) and a shank (3) respectively having a diameter smaller and greater than the lower part diameter (19) of the housing (11) so that the shank (3) forms a shoulder (9) with the drilling part (5), and in that step a) for drilling the bore includes the drilling of the pencil (23) until the said shoulder (9) of the drill bit (1) is positioned to a stop against the shoulder (21) of the housing (11).

A hammer tool including a single body and over-molded with one or more materials configured to improve the performance of the hammer is disclosed. The hammer may be formed with a single piece hammer head defining a cavity at least partially filled with a flowable material, such as steel shot. The striking surfaces of the hammer may be reinforced by a woven fabric or fiber reinforced polymers. The resulting hammer body and cavity has fewer or no joints or seams for shot to escape and provides material properties to be optimized in different areas of the hammer over-mold.
