Abstract: The invention relates to press tools for the connection, by cold forming, of tubular workpieces (2, 3) whose connection regions are provided with circular external cross-sectional shapes and are pushed one into the other. The press jaws (10) of the press tool have, in the closed state, approximately the external cross-sectional shape of the workpieces and can be provided with recesses (13, 17).

Abstract: A tool for extracting a glow plug includes an externally threaded shaft, an internally threaded sleeve that engages the externally threaded shaft, and a fixed cavity formed in one end of the externally threaded shaft. The cavity has a side entry to permit the insertion of the glow plug into the cavity in a direction normal to the shaft, and a pair of opposing shoulders integrally formed in opposing sidewalls of the cavity to engage the glow plug.

Abstract: A glo-plug extractor is disclosed. An internally threaded sleeve is threaded over an externally threaded bolt having a bolt head at one end and a set of jaws at the other. The jaws are fitted to lock onto the head of a fully unscrewed, yet bound glo-plug. After the jaws are locked onto the glo-plug, the sleeve is braced against the engine head either by screwing the sleeve down over the jaws until it contacts the engine head or by placing some bracing apparatus such as a spacer or a set of legs between the sleeve and the engine head. Once the sleeve is braced, it must be locked in place using a locking apparatus such as vice grips or a wrench. The bolt head is then used to rotate the bolt relative to the sleeve. This rotation causes the sleeve to exert a pulling force on the bound glo-plug which either extracts the glo-plug whole or breaks it.
