摘要： 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.

摘要： An underreamer drill bit assembly including a pilot bit (82) and extendable underreamer arms (88) operatively connected to the pilot bit (82). The underreaming arms (88) have an extended position for underreaming, and a retracted position in which the overall diameter of the underreamer drill bit assembly is less than the inside diameter of the well casing, permitting the entire bit assembly to be withdrawn through the well casing. In another aspect of the invention, the bit assembly is operatively connected to a dual wall pipe assembly (12). A supply of compressed air is conducted through the annulus (24) of the dual wall pipe assembly (12) to a down hole pneumatic hammer (13). Exhaust air from the down hole hammer is directed to the bit assembly for continuous removal of drilling debris through a central evacuation tube (43) of the dual wall pipe assembly. In another aspect of the invention, a pressurized, incompressible fluid is injected into the annulus between the well casing and the downhole pneumatic hammer.

摘要： A drilling tool for boring in earth and rock formations includes a pilot bit which defines a longitudinal tool axis and includes a cam part having a cam axis arranged eccentrically relative to the tool axis. A reamer includes a hollow reamer body mounted on the cam part for rotation relative thereto about the cam axis. Relative rotation in one direction causes the reamer to be radially extended, and relative rotation in an opposite direction causes the reamer to be radially retracted. The reamer body carries cutting elements for enlarging a hole drilled by the pilot bit when the reamer is in its extended position. The cam part carries a first removable insert on which a first stop surface is formed. The reamer carries a second removable insert on which a second stop surface is formed. The stop surfaces are engageable with one another when the reamer body is radially extended, for transmitting rotational cutting forces to the reamer. The stop surfaces are formed of a material harder than a material from which the cam part and the reamer body are formed. The stop surface of the insert carried by the reamer may be formed by a plurality of rotary ball bearings.

摘要： In a rotary drag-type drill bit for drilling subsurface formations, at least one formation-engaging member is movably mounted on the bit body so as to be movable in and out, relative to fixed cutting elements, in response to engagement with the formation being drilled. In one arrangement the formation-engaging member (48) is generally pear-shaped and is bonded within a body of rubber (49) within a tubular sleeve (50) screwed into a threaded socket in the bit body (51). The body of rubber (49), confined within the sleeve (50), offers comparatively solid resistance to impact at right angles to the surface of the bit body. However, when subjected to a force having a sideways component the member (48) tilts against the resilience of the rubber (49), to reduce the extent to which the member projects above the surface of the bit body. The member (48) thus protects an associated cutting element against impact but yields to allow the cutting element to engage the surface of the formation being drilled.
