| A drilling device for drilling a hole in the ground and/or rock and having in its drilling head a plurality of drilling wing bits arranged at equal distribution with their mutual position being adjustable such that the wing bits are located within a minimum diameter dimension and, on the other hand, adjustable such that they are located to drill a hole with a maximum size diameter and that the drilling device is arranged to pull, during drilling, a protective pipe into the hole at least when drilling the hole in the ground. An outer circumference of the wing bits includes a circumferential groove arranged to receive a ring belonging to a front part of the protective pipe, to an inner surface thereof, when the wing bits are adjusted to a diameter size substantially larger than the minimum diameter dimension in order to pull the protective pipe via the wing bits. | ||||||

| The invention relates to a drilling tool and a method for down-the-hole drilling, the drilling tool being intended to drill a hole ahead of a following casing tube (13). The drilling tool comprises a central pilot drill bit (20), a reamer (33) and a guide body (12) for steering the drilling tool and casing tube relative to one another. To avoid problems with threaded connections, the guide body (12), reamer (33) and pilot drill bit (20) are mutually formed so that the rotational power is transferred from the guide body (12) to the reamer (33) and from the reamer (33) to the pilot drill bit (20), but without either of the two transfers of rotational power comprising any threaded connection, and so that an essentially radial displacement exists between the guide body (12) and the reamer (33). The construction also facilitates retraction of the reamer (33) without the pilot drill bit also needing to rotate. | ||||||

| A down hole running tool (14) travels in a first direction through a drill pipe for installing bit segments (18) at the end of a drive sub (12) attached to the drill pipe. The tool (14) includes a first portion (82) and a second portion (84) which is retractably coupled to a leading end of the first portion (82). The first portion (82) includes a tubular extension (134) which receives a spigot (136) that extends from an upper end of the second portion (84). A pin (138) extends transversely through the tubular extension (134) and resides within opposing slots (140) formed in the spigot (136). There is a stepped reduction in the internal diameter at the lower end of the tubular extension (134) so as to form a cup-like structure (146). A spring (168) is disposed about the spigot (136) and has an upper end seated in the cup-like structure (146) and a lower end bearing against an upper face (170) of the second portion (84). The spring (168) is biased so as to push the first and second portions (82 and 84) apart in the longitudinal direction. When the tool (14) is lowered into the drive sub (12) and the second portion (84) hits a stop, the first portion (82) is able to continue movement for a short distance against the bias of the spring (168) by virtue of a gap existing between the surface (170) and the end of the cup-like structure (146). | ||||||

| 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. | ||||||

| 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. | ||||||

| A retractable drill bit system (10) comprises a drive sub (18) which is adapted for connection to a lower end of a drill (12), a tool (20) for installing and retracting drill bit segments (22) from the drive sub (18); and an insert (24) for selectively locking the bit segments (22) to an end of the drive sub (18) and releasing the bit segments (22). A plurality of recesses (5B) are formed about an inner circumferential wall at one end of the drive sub (18) and a landing seat (32) formed about the inner wall upstream of the recesses (58). The area of the interior wall between the landing seat (32) and recesses (58) is profiled with a series of tapered and level surfaces. The tool (20) includes a slidable cradle (176) extending from one end about which the bit segments (22) are held during installation and retrieval. The bit segments (22) being held in place about the cradle by an elastic band (198). The insert (24) is provided at one end with a series of keyways (218) which locate over the bit segments (22) when the bit segments are locked to the drive sub (18). The insert (24) is always retained within the drive sub (18). Bit segments (22) are carried by the tool (20) to the drive sub (18) and locked in place by the insert (24). The tool (20) can then be withdrawn and the drill (12) operated in the normal manner. To retrieve the bit segments (22), the tool (20) is relowered into the drill and then withdrawn a short distance to retract the insert (24) so that the bit segments (22) collapse back onto the cradle (176) and can then be withdrawn from the drill (12). | ||||||

| A drill bit assembly (1) includes a driver (2) adapted for attachment to a down hole pneumatic hammer. A pilot bit (30) is coupled to the driver (2) in a manner permitting rotational and axial movement between driver (2) and pilot bit (30). A series of underreamer arms (19) are disposed intermediate the driver (2) and the pilot bit (30) and engage a centrally disposed cam block (18) on the pilot bit (30). Pivot pins (21) of the underreamer arms (19) are journaled in and move with the driver (2) during partial rotation of the driver during arm deployment and retraction. Passageways (39) in the driver and pilot bit direct compressed air to the working surface of the bit for discharging particles upwardly through channels (41) in the bit and driver. Inclined surfaces (23a) on the underreamer arms (19) cooperate with the lower end of a casing (C) to contribute to arm retraction prior to removal of the assembly through the casing. | ||||||
