If you work on a lot of electrical projects, you should have a good wire stripper stocked in your tool bag. Wire strippers look similar to pliers and are used to remove the protective coating material from wires—something you need to do a lot when repairing wires, setting up speakers, or working on electrical projects. The best wire strippers can also cut wires and cables, crimp wiring, and cut screws.
The Best Wire Strippers
The Expert: I’ve been involved with construction, maintenance, and home renovation for more than 30 years from both a personal and professional standpoint. I owned a maintenance and construction business with my husband for nearly 20 years. I love much about my home—a fixer-upper built in the 1800s that’s located in a rural mountain region of Pennsylvania—but it involves a lot of maintenance and upkeep, so I am always on the lookout for tools or equipment that can make DIY projects easier. I’ve owned and used a variety of wire strippers for a range of common wiring repair jobs.
What to Consider
Before deciding on which electric wire stripper you plan on buying, make sure to consider a few major factors like the type of stripper, the gauge sizes, and basic safety criteria.
Type
Gauged
Sometimes called a manual wire stripper, this type has different notches that correspond to common wire gauges, so you just need to select the correct hole to fit the wire you’re working on. Gauged wire strippers provide set spaces on the tool for a standardized strip every single time. The one downside of gauged strippers is the lack of size options.
Adjustable
Adjustable wire strippers have just one open notch to use, and can be widened or tightened based on your needs and the thickness of wire. This allows for accurate, precise stripping based on each individual wire. Most adjustable wire strippers have a tightening mechanism to ensure that the notch doesn’t widen or grow too tight when in use. Adjustable strippers do rely on your adjustments, however—which, if not precise, may damage the wires beneath the jacket.
Automatic
Also called a self-adjusting wire stripper, this tool automatically conforms to the needed size when you insert the wire. These strippers don’t require any measurements or gauges in order to function. The automatic stripper is only limited by the overall size range it covers.
Gauge Sizes
Wire size refers to a wire’s diameter, which is often measured according to the American Wire Gauge (AWG) measurement system. AWG sizes range from 0000 to 40. It can be confusing, because the thinner the wire, the larger the AWG number. Wire can be solid or stranded; the stranded wires have a larger diameter. The most common gauges of wire in residential settings are between 6 and 14 AWG, but you might be working with gauges outside of that range, depending on the jobs and setting involved. Make sure to select a wire stripper that can accommodate the wire sizes you’ll need, and keep in mind that wire strippers can have different gauge ranges for stripping, cutting, and crimping.
Safety Criteria
Look for VDE certification that indicates a wire stripper has met essential safety standards. The VDE Testing and Certification Institute tests and certifies electrical tools and equipment and is considered the global authority in this area. Typically, wire strippers will be VDE-certified and approved for up to 1,000 volts.
