Tongue-and-groove pliers are a type of slip-joint pliers. They are also known as water pump pliers, adjustable pliers, slippy pliers, groove-joint pliers, arc-joint pliers, Multi-Grips, tap or pipe spanners, gland pliers and Channellocks (i.e., Channellock brand pliers).
They have serrated jaws generally set 45 to 60 degrees from the handles. The lower jaw can be moved to a number of positions by sliding along a tracking section under the upper jaw. An advantage of this design is that the pliers can adjust to a number of sizes without the distance in the handle growing wider. These pliers often have long handles—commonly 9.5 to 12 inches long—for increased leverage. The weight of the tool can also vary, depending on the material used.
The Cobra® QuickSet combines all proven properties of the KNIPEX Cobra® with an additional push on function which makes it easier to work in very confined and inaccessible areas. Adjustment directly on the workpiece is possible by simply sliding the pliers handle. The hinge bolt locks itself with the first workload. The gripping width of the pliers is then fixed and can only be adjusted by pressing the button. The hinge bolt must be released by pressing the button and the pliers must be completely opened once to activate the QuickSet function again.
