Best Wire Strippers – Top 3 for March 2020

Wire strippers are an essential part of any electrician’s toolkit, they are also generally handy to have around your home, shop, or garage. Wire strippers are one of those tools where its appearance massively undermines its value – it just sort of looks like a big pair of scissors but its design and precision turns out to be hugely important.

It is easy to forget that you need a wire stripper in your kit, that is, until you face a situation where you need it. And when you need it you better has a good set because saving $5 on you wire strippers can cost you hundreds in lost time and rewiring.


Why You Need Wire Strippers

A wire stripper is used in removing insulation from around a wire or cable. Sure, you can do this with a normal pair of scissors or a utility knife (and we’ve all seen someone do it with a razor blade), but the chance of damaging the wire is quite high. The change of damaging your hand can be really high too… so just don’t do it!

Some people like to strip wires with the interior of a set of pliers. This method is safe, but not that accurate so the chance of hurting the wire ends up being surprisingly high (in my experience). This might work for a large gauge, tough cable, like a coax, but won’t for something more sensitive.

Wire strippers are one of those tools where they clearly fit a purpose and they are useful enough that you shouldn’t feel like you are buying some sort of one-off tool or gimmick.

What is AWG?

Before we get started, you might be wondering, what is AWG, and why is this acronym spelled out all over the place? AWG is short for American Wire Gauge. This is a gauging system that has been used since the 1850s, primarily in the United Stated (think metric vs. imperial systems). It’s used for explaining the diameter of solid wiring that is specifically used for conducting electricity. Basically, the bigger the diameter, the more amps the wire can handle, so gauge is incredibly important. This importance extends to when you your task it so strip the coating from the exterior of the wire without damaging it.

AWG is for solid wiring, but cabled, stranded wiring is part of this system as well. Stranding wires are treated by the AWG formula to determine the equivalent size solid copper wire.

Fun fact: AWG is also used to the gauge (in this case the hole size) of body piercing. 

Now, on to the wire strippers! There are several wire strippers available on the market, but these three stand out for all the right reasons.

Beware of Budget Wire Strippers

There are lot of tools where it won’t really matter much if you go with the cheapest option. The problem with going with a sub-par wire stripper is that you can end up cutting wire instead of stripping it. And, to be honest, that’s not normally a big deal because you can just toss the wire and start again. But if the wire is attached to something important or means another run to the hardware, then you are going to be kicking yourself.

The set of wire stripper above is as low cost as they come (about $8) — and I know since they’re mine! All these are is two pieces of stamped steel with a long channel cut in one side. In that channel is a nut and bolt which can be moved up and down in order to limit the size of the notch cut into the business end. This system can work, but you are just doing your best to get to the right size. That means you aren’t using AWG or any standard measurements, you’re just getting close enough.

In addition to being inexact, there are problems with these cheap wire strippers. The first is that the bolt can come come loose, messing up your next move. Also, the nut on the adjustment bolt is tiny and requires wrench, so you need at least two tools with you. Lastly, these wire strippers are “spring-assisted” but the spring breaks every time I use it, so they are rather annoying as well.

Considering that the excellent wire strippers below tend to cost under $20, my advice would be to get a good pair since the cheap ones will definitely cost you more than $10 within the first few times you use them.
