The Neiko 01924A is a 3-in-1 automatic wire stripper that strips, cuts and crimps in one 8 inch tool. It is one of the most popular budget automatic strippers, and it suits anyone who wires more than a few connections at a time.
This review covers how it works, what its specs mean in practice, what owners report after long use and where its limits are. It is built from Neiko’s published specs and verified owner reviews. I have not used this tool in person, and I say where a point comes from owners.
Verdict: a strong budget pick for household, hobby and automotive wiring. Step up to a dedicated ratchet crimper for heavy lugs. Check Price on Amazon
Neiko 01924A at a Glance
- Best for: DIYers, hobbyists and light trade work from 10 to 24 AWG
- Main strength: one-handed self-adjusting stripping
- Main limit: the crimp jaw is light duty
- Skip it if: you mainly crimp heavy battery lugs or strip very fine electronics wire
How an Automatic Wire Stripper Works
A manual stripper makes you pick the right gauge hole for every wire. An automatic stripper has two sets of jaws: one grips the wire, and the other cuts and pulls the insulation in the same squeeze.
The self-adjusting jaws sense the wire size, so you can move between gauges without changing a setting. That saves time on jobs with mixed wire, such as a light fixture with 14 gauge feeds and thinner fixture leads.

What the Specs Mean on the Job
Stripping Range
The 10 to 24 AWG range covers standard household circuits, from 10 gauge for dryers and water heaters down to 24 gauge for thermostat and doorbell wire. It also covers most automotive wiring. For wire thinner than about 20 AWG, the thumb wheel adds grip so fine strands do not slip.
Strip Length Stopper
The red flip-up stopper sets how much copper is exposed, from 1/4 to 3/4 inch. That matters for clean terminations, since too much bare copper at a device terminal is a safety problem. Set it once and every strip comes out the same length.
Cutter and Crimper
The cutter in the nose handles the same 10 to 24 AWG range. The crimp section takes insulated terminals from 10 to 22 AWG and non-insulated terminals from 4 to 22 AWG. For everyday spade and butt connectors that is plenty, but heavy lugs need a ratchet crimper.
What Owners Report
Owner reviews most often praise the one-handed stripping and how quickly it switches between gauges. Many say it does not nick the copper when the thumb wheel is set correctly. Owners describe the build as solid for the price, and long-term reviews say the jaws keep their grip on insulation after months of regular use.
The most common complaints are about very fine wire, where the thumb wheel needs careful setting, and about the crimp jaw on larger terminals. A few owners also note that it ships without a case.
How to Use the Neiko 3-in-1 Wire Stripper
- Turn off the circuit at the breaker and confirm it is dead with a voltage tester.
- Flip the stopper to set the length of bare wire you need.
- Place the wire in the jaws, with the end against the stopper.
- Squeeze the handle fully in one smooth motion.
- Check the copper for nicks or cut strands before you terminate it.
- For thin wire, tighten the thumb wheel a little and try again if the insulation does not pull cleanly.
I always stress step 1. No stripper is insulated for live work, so the circuit must be off before you start.
Pros and Cons
Pros
- True one-handed automatic stripping
- 10 to 24 AWG range covers most household and automotive jobs
- Cutter and crimper built into one tool
- Light aluminum frame with a spring-loaded handle
Cons
- Crimp jaw is light duty for heavy lugs
- Very fine strands need the thumb wheel set carefully
- No case included
Neiko vs Other Wire Strippers
Against the IRWIN VISE-GRIP self-adjusting stripper, the Neiko adds a more capable crimper and a strip length stopper. The IRWIN is simpler and has a long track record. Both are covered in our best self-adjusting wire strippers roundup.
Against a manual stripper such as a Klein Kurve, the Neiko is faster on mixed gauges. A manual stripper is slimmer for tight boxes and has no mechanism to wear out, so many electricians carry both.
Frequently Asked Questions
What gauge wire does the Neiko 3-in-1 wire stripper handle?
It strips and cuts copper and aluminum wire from 10 to 24 AWG. The thumb wheel improves grip on wire thinner than about 20 AWG.
Can it crimp connectors as well as strip wire?
Yes. It crimps insulated terminals from 10 to 22 AWG and non-insulated terminals from 4 to 22 AWG. For heavy battery or welding lugs, use a dedicated ratchet or hydraulic crimper.
Can I use it on live wires?
No. It is not an insulated tool, so always switch off the circuit and test it first. For live work near panels, use rated tools like those in our 1000V insulated screwdriver guide.
Is it good for beginners?
Yes. The automatic action removes the guesswork of picking the right gauge hole. Beginners still need to check every strip for nicked copper.
Final Verdict
The Neiko 01924A is an easy budget recommendation for anyone who strips wire often. It is fast, simple and covers the gauges most homeowners and DIYers use.
