Choosing Wire Cutter Tools


If you need to cut wires, you have two main choices: you can use a diagonal cutter or a ratcheting cable cutter.

The latter is a more convenient option because it can be used to make precise cuts that are easy to remove from the wiring.

Diagonal cutters

Diagonal wire cutters are a type of plier. They are used to cut metals and cables in a smooth and clean way. Most commonly they are used by electricians.

These tools are usually made of steel and are springy. However, there are also some with additional features such as a gripper. Other types of pliers have ridged surfaces, blunt blades, or a crimper.

Generally, a high leverage diagonal cutter is better suited for long term and continuous use. It is also appropriate for applications that involve permanent stress.

Some wire cutters include return springs and a tether split ring. These features help protect against shock and damage. In addition, they are VDE approved.

Maun diagonal cutting pliers are designed for cutting hard piano wire. Their special design ensures an efficient, precise and comfortable grip.

The ergonomic bow handle provides exceptional comfort. The zinc-plated handles have added detailing and have a classic finish. This tool is great for dental technicians and electricians.

Knipex Diagonal Wire Cutters feature induction-hardened blades and are designed for precise cutting. Additionally, they feature a transmission ratio, ergonomic handles, and long tool life.

Cuda 6.75″ Titanium Bonded Diagonal Wire Cutters are designed for cutting soft and hard wires. These durable blades are three times harder than untreated steel.

Ratcheting cable cutters

Ratcheting cable cutters are an excellent way to cut through the large-diameter cable. This type of cutting mechanism also makes it easier to slide fittings onto the wire.

Typically, they require two hands to operate, and they come in a variety of sizes. The heavy-duty version is especially handy for working in tight spots.

The ratcheting cable cutters from Klein Tools(r) are a solid choice. They offer a wide range of features, including a patented two-step ratcheting mechanism that makes

it possible to cut aluminium and copper wire with fewer strokes. In addition, the cutter’s hardened steel blades provide extra sharpness and durability.

Southwire’s CCPR400 Heavy Duty Compact Ratcheting Cable Cutters are another good choice.

They feature a quick-release lever, comfortable moulded grip handles and hardened steel blades that cut up to 750 kcal copper and 1000 kcmil aluminium.

Their high-leverage ratchet mechanism makes it possible to cut large-diameter cables without splaying the ends.

Although they aren’t quite as powerful as power cutters, ratcheting cable cutters still make the cut.

And their two-step ratcheting mechanism provides even pressure that eliminates the chance of burring or flattening the ends of the wires.

Moreover, the curved sickle-like blades clamp down more forcefully with each pump of the handles, which makes it possible to cut thicker cables with fewer passes.

Knife to cut through wire insulation

If you’re repairing or installing electrical wiring, you’ll likely need to cut through wire insulation. The process may require a knife, a screwdriver, or a combination of tools.

It’s important to choose a safe and effective tool. Otherwise, you might find yourself sidelined for weeks or even months.

Wires come in a variety of shapes and sizes. They range from millimetres to centimetres in diameter. Smaller wires tend to bend before they’re cut.

Larger-diameter wires, like copper wire, are easier to handle. Similarly, insulated wires should be handled with care.

When removing wire insulation, the key to success is determining the right tool for the job. Using the wrong tool could lead to damaged wiring or even an injury.

Most savvy electricians will use a wire stripping machine. A wire stripper is much more accurate and faster. Some models are available for less than $50. Those with insulated handles help keep you safer.

You can also try sandpaper to remove wire insulation. However, this is not a recommended method because it can damage the wire. To avoid this problem, make sure you’re working in a well-ventilated area.

Another good alternative is a hot wire cutter. These are designed to cut common insulation foam. This type of tool can be used to cut copper, aluminum, and other metals.
