End nippers, also known as end-cutting pliers, are an excellent tool for cutting thick, strong wire. They are most effective with electrical wire, but they can also cut neatly through piano wire and other heavy materials. End nippers come in two types: open-end and closed-end.
Open-end nippers have flat, fixed blades that bend away from you when closed. You use them to cut thin wires, such as those used in jewelry making. Open-end nippers are easy to use because you simply slide a piece of wire between the blades and pull them together. The wire is cut when it reaches the point where the blades meet.
Closed-end nippers have one fixed blade and one sliding blade. They are more useful than open-ended nippers because you can use them to cut thicker wires. Also, the shape of the closed nipper's cutting edge allows you to cut curves in wire. Like open-ended nippers, you slide a piece of wire between the blades and pull them together to cut it. But instead of releasing immediately, the second blade slides along the first blade to create a tighter loop around the material you want to cut. Then, you squeeze the handles of the nipper together, which closes the gap between the blades and cuts the wire.
Selecting a Cutting Tool To splice or cut electrical lines, use Lineman's pliers. Lineman's pliers include a cutting device on the side and are used for a variety of construction and electrical applications. This is the safest option for gripping, stripping, or cutting any type of electrical wire. They're perfect for cutting back the insulation from a spent conductor before connecting it to another set of wires or a load.
Lineman's pliers are available in different sizes and shapes depending on the application. The most common types are listed below:
Linear Liner's pliers have one fixed blade and one movable blade that can be aligned with each other. They are best for making tight bends in small pieces of wire because their blades don't close completely like larger pair-pointed tools do. These tools are ideal for pulling cables through confined spaces such as pipes or holes in walls.
Barbed Liner's pliers have two fixed blades with barbs attached to them. They are best for stripping cable jackets off of large sections of wire because they can grip the material while moving along the length of the tool. Barbed liners are also useful for ripping apart old wiring systems and finding short segments of wire that might be able to be reused elsewhere.
Barbed Pair-Pointed Liners have four fixed blades with barbs attached to them.
Although needle-nose pliers are typically used to cut and bend thin wires and electrical cables, they also have other use. They can bend, cut, and grab in places where fingers and other tools would be too large or awkward. They are not strong enough to cut massive, tough wires and should never be used on live electrical cables. However, when used properly, they can shave off small sections of larger wires and cables without damaging the surrounding material.
Needle-nose pliers are a must for any toolbox. They are easy to use and very effective for cutting wires and cables. Not only that but they can also twist, pull, and pry apart materials that more rigid tools cannot. Although many people prefer using wire cutters for shorter lengths of cable, needle-nose pliers are still useful for longer pieces of wiring because you do not need to scrape off all the insulation to get to the metal core.
Needle-nose pliers come in several sizes from which to choose depending on the length of wire and cable you need to work with. There are standard size needles for each pair of pliers, then there are smaller ones for fine work and larger ones for bending heavy duty wire. You will also find replacement needle tips available online or at hardware stores. These replace the plastic part of the tip that contacts the wire or cable and can be used again after filing down its edge slightly with a file or sandpaper.
