A diagonal cutting plier is a versatile tool that combines gripping and turning functionality with a cutting capacity. These tools are designed to cut through a variety of materials including electrical wires. The handles are normally coated with an insulating material protecting the user. The Pliers are used by electricians, carpenters, plumbers, and other skilled workers. However, these tools are simple enough to be wielded by just about anyone. The plier can be used to hold a nail perpendicular to the surface into which it is to be hammered. This will prevent the user’s fingers from accidentally bearing the impact of the hammer should it slip. This is especially true for small and thin nails. The pliers can also be used to grip and unscrew nuts, bolts, and even water pipes. The stripping functionality in some pliers involves peeling away the insulation coating of wires without harming the wire within. Those cutting pliers that have a crimping facility have notches that can be pressed down on crimp beads and crimp tubes, aside from solderless connectors and electrical terminals. These pliers can cut through screws, nails, and even tough wire.
Features and working of a diagonal cutting plier The diagonal cutting plier is normally subjected to immense stress and strain. At the same time, the gripping action needs to be accurate and sturdy. Therefore, most pliers are made of fine polished, high carbon drop forged steel. A plier is basically composed of three parts; the head containing the jaws, the handles, and the pivot. The pivot forms the ‘axle’ of the plier and provides the necessary leverage for the tool to work. The cutters are precisely mated and heat-treated to maintain their edge. Sometimes, the cutting edges are electronically hardened. The pliers incorporate a curved diagonal for better leverage. The efficiency of the tool increases the power output with minimal energy expended by the user. This is possible due to the fact that the handles of the tool are longer than the jaws, resulting in the amount of force being exerted by the user on the handles being magnified in the jaws. The plier can easily cut 4/0 aluminum and 2/0 soft copper. The cutting capacity is improved further with curved 30 degree offset cutting jaws that are hard honed and induction hardened. Some pliers have an overlapping diagonal cutter. The cutters are made sharp enough to cut through resilient wires. The tool jaws are knurled and have teeth for better gripping. An average diagonal cutting plier has a length of around 10 to 16 inches and a cutting length as well as jaw length of approximately 27/32 inches. The head and the handle are usually completely polished, having matted grips. Some pliers have an adjustable screw to limit the extension of the jaws. An intrinsic spring ensures that the jaws return to the opened position after being squeezed together. In certain pliers, the notch at the rear part of the head, behind the jaws and the pivot, is used for cutting wires. What to look for in a diagonal cutting plier The design of the pliers, as well as the length of the handles, and the location of the pivot are judiciously designed to get the maximum leverage from the tool. The handle grips are ergonomically contoured and coated in a rubber or plastic padding to increase the comfort Level of the user. Sometimes the outer surfaces of the grips are serrated to provide a non-slip grip. The pliers are generally perfectly balanced with broader handles offering a firmer grip. Strain on the user’s wrist is minimized with spring loaded handles. The exposed parts of the tool are coated with an anti-rust lacquer layer to increase the life of the plier and prevent undue corrosion. Durability is further enhanced with the milled jaws being tempered and hardened. Heavy duty flat shafts do not flex as much as other conventional pliers. Some pliers incorporate multiple functionality into one unit; a crimper, multi-crimper, variable-size wire stripper, wire cutter, bottle opener, and even a small nut wrench. A narrow and tapering tip in front of the jaws would ensure that the pliers can be used even in tight and relatively inaccessible locations. Some reputed manufacturers of diagonal cutting pliers include Channellock, Grip, Performance, and Titan.
