Disclosed herein is a ratchetable wrench, with, in some embodiments the ability to interchange wrench heads for working with various styles of rotatable fittings. The disclosed ratchetable wrench includes a two-pawl ratchet mechanism for use with an open-ended wrench head. The two-pawl mechanism allows the wrench head to be freely rotatable relative the wrench body when the pawls are in a user-selected tooth-disengaged position such that the pawls are disengaged from teeth located about the periphery of an installed cogged wrench head and rotatable only in one direction relative the wrench body when the pawls are in a tooth-engaged position. A plurality of interchangeable wrench heads for use with an embodiment of the ratchetable wrench and a method of the interchanging various wrench heads are also disclosed herein.

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.

An improved parallel-jaws locking wrench/plier with toggle action includes a body element, a fixed jaw, and a moving jaw capable of moving rectilinearly by means of an action cam, which is pivotally connected to a locking lever coupling respectively to the upper ends of a fulcrum bar and a releasing lever thereof. A handle secured to the body element has an axially adjustable screw to regulate the opening of the jaws. This is the chosen embodiment to develop this invention, which enables the toggle wrench/pliers to use interchangeable jaw sets with simple and convenient steps.

A locking mechanism is described herein that is attachable to tubing or casing tongs to maintain the engagement of a clamping apparatus of the tubing or casing tongs with a tubular member using only the locking mechanism and the tubing or casing tongs. The tubing or casing tongs can also include a handle for supporting the clamping apparatus that engages the tubular member. The locking mechanism can include a pitman arm rotatably supported by the handle of the tubing or casing tongs. The locking mechanism also includes an adjustable sleeve slidably supported by the pitman arm and a tension arm rotatably supported by the adjustable sleeve to engage with the clamping apparatus.
