Abstract: A drill adapted to be detachably and pivotably linked to a wire fishing adapter for pulling wiring through a bored-out passage in a wall or the like, including a blade-type drill bit having a pin protruding from one of the faces of the drill bit blade, a rod having a pair of spaced-apart apertured fingers at one end and having a conically-shaped receptacle at the opposite end for lockable engagement with the end of a wire.

Abstract: A press for hydrostatic extrusion of tubes includes a high pressure cylinder axially displaceable in a press stand with a die insertable into the cylinder and a pressure generating punch insertable into the cylinder to generate the pressure for extrusion. A mandrel is carried by a rod which passes through the pressure generating punch. Seals are provided between the mandrel and the pressure generating punch and between the pressure generating punch and the pressure cylinder. These seals are so located that during the actual extrusion they are arranged in the same transverse plane.
