This method is a simple and effective way to strip wire quickly and efficiently. With the right tools and a bit of practice, anyone can learn how to strip wire using diagonal cutters.

Prepare The Wire

Prepare The Wire

When preparing wire for a project, the first step is to strip the insulation. This can be done using a pair of diagonal cutters. Start by gripping the wire with the cutters at the point where you want to strip the insulation. Squeeze the handles together to cut through the insulation.

Avoid cutting into the wire itself while doing this. Once you have cut through the insulation, gently pull away the cut pieces to completely remove it. If needed, use a brush to remove any residual pieces of insulation.

You may also need to use some sandpaper to remove any burrs. Finally, inspect the wire to make sure that it is clean and ready for the next step in your project.

Gather Materials

Now that you have decided to strip wire using diagonal cutters, it’s time to gather the necessary materials. First, you’ll need a pair of diagonal cutters. Make sure the cutters are sharp and in good condition so that you can make a clean cut.

Additionally, you’ll need some wire, which should be of the appropriate gauge for the task at hand. If you don’t already have wire, purchase it from a hardware store. You will also want to collect a few other materials, such as a wire stripper, tape, a pair of gloves, and safety glasses. Having the right materials for the job is essential, so make sure you have everything you need before you start.

Choose Proper Gauge

Choosing the proper gauge for your wire is an important step when stripping wire with diagonal cutters. The wire gauge refers to the size of the wire and is typically marked on the side of the wire. The lower the gauge number, the thicker the wire will be. Generally, a wire that is 20 gauge or thicker should be cut with diagonal cutters.

Thinner wire can be cut with scissors. If the wire is too thick for the cutters, they can become damaged or they can be difficult to use. Additionally, if the wire is too thin, it can be difficult to get a good grip with the cutters. Make sure to select the right gauge for the job so that you can strip the wire effectively.

Identify Live Wires

Identifying live wires is a critical safety step before attempting to strip wire using diagonal cutters. It is important to ensure that the wire you are working with is not live before attempting to strip it. To identify live wires, you should use a voltage tester.

The voltage tester will indicate if the wire is carrying a current. If the voltage tester detects a current, the wire is live and should not be stripped with diagonal cutters. If the voltage tester does not detect a current, then the wire is safe to strip.

Additionally, you should take extra caution when working with wires that are embedded in walls or ceilings, as they may be more difficult to identify. Taking the proper safety precautions when attempting to strip wires is essential for ensuring your safety and the safety of others.

Cut Insulation

Cutting insulation off of wire is a necessary skill when stripping electrical wire. The most efficient way to do this is with a pair of diagonal cutters. These are small, hand-held pliers that have angled blades on one end. To use them, place the insulation of the wire between the blades and squeeze.

The blades will cut through the insulation and leave a clean cut. Make sure to cut away from yourself so that the blades don’t snap back and injure you. Additionally, keep the blades well lubricated with oil so that they don’t get stuck while cutting. Lastly, be sure to always wear eye protection to guard against any pieces of insulation that may fly up.

Strip The Wire

Strip The Wire

Stripping wires using diagonal cutters is an essential skill for any electrician or DIY enthusiast. To do this, start by choosing the right size of cutter for the job. You will need a pair of diagonal cutters with cutting edges that are slightly larger than the diameter of the wire you want to strip.

Next, you should firmly grip the wire with the cutter an inch or two away from the end. Then, apply a slight pressure while cutting through the insulation. Finally, gently pull the insulation away from the wire to reveal the bare conductor. To avoid damaging the conductor, be sure to use a clean cut and avoid twisting the insulation as you remove it. With practice, you will be able to strip wires like a pro.

Grip Wire Firmly

When using diagonal cutters to strip a wire, the most important step is to firmly grip the wire. This is a safety measure, as it will prevent the wire from slipping and the cutters from slipping, which could cause injury. Make sure that your grip is not too tight, as it will cause the wire to bend and break. Make sure that the cutters are firmly held, as well, to ensure accuracy when cutting.

Place the wire in the center of the cutters and squeeze lightly. This will help ensure that the wire is held in place while you make the cut. When you are ready to make the cut, push down firmly and make sure that the cut is clean and straight.

Cut Insulation

Cutting insulation is an important part of using diagonal cutters to strip wire. To begin, select the size of the cutters that is appropriate for the wire insulation you are cutting. Be sure to select a size that will cut the insulation cleanly without damaging the wire itself. Then, place the diagonal cutters around the wire insulation, just above the point where you wish to cut.

Squeeze the handles of the cutters together firmly and make a single, clean cut. The cut should be made at an angle so that the wire is exposed at the end of the cut. Once the insulation is cut, use your fingers to peel the insulation away from the wire.

Carefully pull the insulation away from the wire until it is completely removed. As you pull the insulation away, be sure to hold the wire steady so that it does not pull with the insulation. If you are not comfortable making a diagonal cut, consider using a hot knife to cut the insulation instead. A hot knife allows you to make a clean cut without damaging the wire itself.

Cutting insulation with diagonal cutters is a simple task that will help you quickly and effectively strip wire. Once you have the hang of it, you will be able to strip wire quickly and efficiently.

Remove Insulation

Removing insulation from a wire is a simple task that can be completed with a pair of diagonal cutters. Begin by ensuring that the wire you are working with is not live. Next, snip the insulation from the wire with the cutters, making sure to cut as close to the wire as possible. Be careful not to nick the copper wire while cutting the insulation.

Once the insulation has been cut, use a pair of pliers to gently pull away the insulation from the wire. If the insulation is hard to remove, try using a flathead screwdriver to pry it away. Be sure to be careful not to damage any of the underlying copper wires.

After the insulation has been removed, you should inspect the wire for any signs of damage. Lastly, use a wire brush to remove any leftover insulation and debris from the wire. Once the wire is clean and free from any debris, it is ready to be used. With the proper tools and techniques, you can easily remove insulation from a wire.

Smooth Edges

When using diagonal cutters to strip wire, it is important to create a smooth edge. This is achieved by keeping the cutters’ blades perpendicular to the wire and cutting in one single motion. Begin by opening the jaws of the cutters and placing the wire in the middle. Position the jaws so that the blades of the cutters are perpendicular to the wire, and close the handles firmly.

Squeeze the handles together in one single motion, making sure to keep the blades of the cutters perpendicular and flush with the wire. Doing this will give you a smooth edge on the wire. If the edge is not smooth, it may affect the connection of the wire when it is used in a circuit. Therefore, it is important to ensure that the blades are perpendicular and flush with the wire when cutting.


Stripping wire with a pair of diagonal cutters is a simple task that requires little effort. First, use the cutters to cut off the insulation surrounding the wire. Then, use the cutters to carefully cut away any remaining insulation, making sure to not damage the copper wire.
