    • The invention relates to an excavation tool, having a pair of insertion holes placed in the bottom surface of a device (10), which receives the impact force of a hammer and the rotational force of a hammer cylinder, at positions separated in a radial direction from the center of the device (10) and symmetrical around this center as a center of rotation, also having block axles (20), one end of each of which is freely rotatably inserted into one of the insertion holes, and having blocks (22), which have a roughly semicircular shape with a diameter roughly equal to that of the device (10), into the lead end surfaces of which are set bits (21), and which have straight edge surfaces which are flat surfaces vertical with respect to the lead end surfaces, provided at the other end of the block axles (20) and with the straight edge surfaces (22) in mutual opposition. In an extended diameter state of the blocks (22), the blocks (22) are moved in opposite directions along a radius of the device (10) by rotating the blocks (20) around the block axles (22), and the distance between the centers of the insertion holes provided in the bottom surface of the device (10) and the center of this device (10) is set at from 0.2 to 0.3 times the diameter of the bottom surface of the device (10).

    • Die Vorrichtung zum unterschneidenden Räumen von zylindrischen Bohrlöchern umfasst ein mittels eines Antriebs drehbares rohrförmiges Trägergehäuse 1 für zumindest ein Räumwerkzeug 4, das aus einer Ruhelage innerhalb der Querschnittskontur des Trägergehäuses 1 nach aussen in eine Arbeitsstellung, in der das Schneidglied 10 des Räumwerkzeugs 4 über die Querschnittskontur des Trägergehäuses 1 vorsteht, und in die Ruhelage zurück bewegbar ist. Für die auswärts gerichtete Zustellbewegung des Räumwerkzeugs 4 ist eine im Trägergehäuse 1 angeordnete, von einem Bereich ausserhalb des Bohrloches her betätigbare Stellvorrichtung 6 vorgesehen. Zur Verringerung des Bauaufwandes und der Baugrösse umfasst das Räumwerkzeug 4 als Träger für das Schneidglied 10 ein Schlepporgan 9, das in einer sich mit dem Trägergehäuse 1 verschneidenden Bewegungsebene aus- und einwärts verlagerbar am Trägergehäuse 1 abgestützt ist und lediglich an einem in Arbeitsdrehrichtung 5 im Umfangsabstand dem Schneidglied 10 vorauslaufenden Ende mit dem Trägergehäuse 1 zu Zugverbindung steht.

    • A drilling tool of the present invention includes: a casing pipe; a ring bit having a larger diameter and disposed coaxially on a tip side of the casing pipe; and a pilot bit inserted into the ring bit through the inside of the casing pipe. An outer peripheral part at a tip of the pilot bit is provided with a bit head which is extended when rotated in a tool rotation direction during drilling. The ring bit is provided with a part to be engaged that is engaged with the extended bit head in the tool rotation direction, and a first abutting part capable of abutting against the extended bit head in a direction of an axis.

    • An ice auger (20) has a rotatable rod (52) adjacent and parallel to the central shaft (21) supported at the bottom in a cylindrical receptacle (56). A vertical ice reaming blade (51) is attached to the rod (52) above the receptacle (56) and a retaining loop (57) affixed to the shaft (21) and positioned above the ice reaming blade (51) prevents the rod (52) from rising out of the receptacle (56). A right angled handle (53) at the top of the rod (52) extends outward above and in the same plane as the ice reaming blade (51). A spring biased latch assembly (55) disposed near the top of the shaft (21) engages the handle (53) with the ice reaming blade (51) in rest position. Releasing the latch (55) frees the rod (52) to rotate 180° and move the ice reaming blade (51) to use position extending outward beyond the standard auger members to ream the bottom of the ice hole (37). Vertical support posts (61, 62) stabilize the system and prevent wobble. One post (61) functions as a stop and back support for the ice reaming blade (51) during use.
