Module three: Core Electrician's Tools
Also known as Linesman's pliers or Engineers' pliers, these are perhaps the most common type of pliers found in a toolkit.
As their name implies, they have a combination of features designed to make them versatile.
The flat serrated jaw is used to grip and bend sheet metal or bars. An electrician would also use this part of the pliers to twist together stranded copper wire before making a connection, or for doubling over solid core wire.
The curved serrated jaw part is designed for gripping round metal rods or tubes. It can also be used for holding screw heads or nuts.
Close to the pivot (where the greatest force can be applied) is a pair of cutting blades known as side cutters. They are called side cutters because the cutting edges are on one side of the jaws so that they can be used to cut close to a surface.
The side cutters will cut very hard wire (such as spring steel) without damaging the blades.
As the hardness of the wire being cut reduces, the diameter of wire that can be cut increases.
