An adjustable dual-range wrench including an elongate handle and a fixed jaw carried by the handle. The fixed jaw includes multiple teeth disposed linearly along the jaw. A hook jaw is pivotably coupled to the handle opposite the fixed jaw. A toothed lobe is adjustably positioned along the fixed jaw between an outer engagement region sized to engage a first range of sizes and an inner engagement region sized to engage a second range of sizes. The hook jaw comprises a first set of teeth associated with the outer engagement region and a second set of teeth associated with the inner engagement region.

A reciprocating wrench for quick combining fastener includes a main body, a claw, and an elastic positioning device therebetween. The main body includes a concavely-shaped first jaw opening, which has a pivot end at an end thereof. The claw includes a concavely-shaped second jaw opening, which has a pivotal combination portion at an end thereof. The pivotal combination portion is pivotally connected with the pivot end, such that the claw and the main body pivotally move with respect to each other. The elastic positioning device allows the claw to optionally rotate toward a closing direction or remain in the opening status. Therefore, the claw is able to remain in the opening status for combining the fastener.

A torquing tool having an apertured head supporting a perimetral toothed surface closable about a rotary object in a self-fitting/clamping manner, wherein the aperture head provides a ratchet enable pawl operatively associable with the perimetral toothed surface.

Infiltrated diamond bodies for use in gripping drill rods and other tubulars. One example of such an infiltrated diamond body is a cast diamond roller having a plurality of pads that are separated by channels. Another example of such an infiltrated diamond body is a cast wrench jaw having at least one raised jaw pad.

A pipe plier structure includes a first body, a second body, a pivot member, and a locking member. The first body is provided with multiple first teeth, an arc line, an axis, a first vertical line, a radius, a first angle, and a second angle. The second body is provided with multiple second teeth, multiple third teeth, a second vertical line, a first connecting line, a second connecting line, a third angle, a fourth angle, a concave face, a fifth angle, a sixth angle, a seventh angle, and an eighth angle. The pivot member is assembled with the first body and the second body. The locking member is assembled with the first body and the second body. The locking member provides an elastically restoring force to the first body and the second body after the second body is extended outward relative to the first body.

A truly one-handed operable pipe wrench is provided which includes a handle having a first end and a second end, a fixed jaw disposed at the second end of the handle, and a rotatable jaw pivotally attached to the second end of the handle. The rotatable jaw includes a first engaging end and a second driven end. A lever arm is pivotally attached to the handle. The lever arm includes a handle portion and an actuating portion. When the lever arm rotates relative to the handle, the actuating portion is in contact with the second driven end of the rotatable jaw causing the rotatable jaw to rotate relative to the second end of the handle.

A safety handle for use with conventional pipe tongs. The safety handle has a hand grip, as well as upper and lower flange members. The flange members beneficially define a recess for receiving (and protecting) a user's thumb. At least one attachment cavity is provided for receiving, and securely attaching the safety handle to, a tong jaw member.

A hook jaw is pivotably coupled to the handle opposite the fixed jaw. A toothed lobe is adjustably positioned along the fixed jaw between an outer engagement region sized to engage a first range of sizes and an inner engagement region sized to engage a second range of sizes. The hook jaw comprises a first set of teeth associated with the outer engagement region and a second set of teeth associated with the inner engagement region.

The wrench has a thumb switch, when operated, opens against a spring bias the pivotal ring portion around the axis pin attached to the fixed head portion of the wrench head portion, allowing a tube or pipe attached to the fastener to access the confines of the wrench head hexagonal inner profile via the said access channel now provided, the opening of the pivotal ring portion involves approximately 50% of the wrench head portion, the said pivotal ring portion encompassing approximately 50% of the wrench head inner profile. The corner profiles next to the swivel joints are scalloped such that when the pivotal ring is opened the scallops substantially align forming a passageway required for the abutting fastener drive corner to traverse through.
