How to Make an Effective Wire Stripper

How to Make an Effective Wire Stripper

If there is a large volume of work with electrical wires (replacing lines, repairs, etc.), you cannot do without a special device for exposing the ends of the wiring. There are special mechanisms that facilitate this labor-intensive process, but few people know that in five minutes, practically from improvised means, you can make a simple and effective device for cleaning cables of different diameters (from 10 mm and less).

What you need to have on hand


  • A piece of plastic pipe for wiring installation (outer diameter 20 mm);
  • Large blade from a stationery knife (width 16 mm);
  • Plugs from the installation box (2 pcs.);
  • Among the tools we will need a drill with a set of drills for metal (wood), a saw, a sharp knife, sandpaper, a tape measure, a marker and a vice.

Preparing the knife holder


How to Make an Effective Wire Stripper

To begin, cut off a piece of pipe 14 cm long. Using sandpaper and a sharp knife, remove burrs from the cut. We apply markings to the pipe at intervals of 2 cm so that we have 6 marks.

We will need drills with a diameter of 10, 8, 6, 5, 4 and 2 mm. We start with a larger diameter.Clamping the drill in the chuck and the pipe in a vice (with the marks facing up), we make a cut in the pipe, pressing the rotating drill with its side in the center of the mark and performing reciprocating movements.

The immersion depth of the drill should not be greater than its thickness. The resulting oval-shaped holes should be cleaned of plastic residues using a knife.

Blade insert


How to Make an Effective Wire Stripper

The blade must be inserted into the pipe so that the cutting edge is located strictly in the middle of all holes. It enters with very great force (and we need to insert it completely), so to facilitate the process, we need to use the other hand to squeeze the pipe from the sides, parallel to the plane of the blade, as much as possible, while simultaneously pushing it inward.

After that, we install plugs from the distribution box on the edges of the pipe and everything is ready. Tests can be carried out.

How to properly use a homemade insulation stripper


The groove that best matches the cable diameter is selected. The wire itself is laid directly into it so that the knife line is in the place where the insulation should be removed.

At this point, the wire is pressed with a finger against the inner blade and the wire is rotated in a circular motion in any direction. The depth of cut can be adjusted by pressing your finger. Then, holding the wire in the recess with the same finger, with the other hand you should pull it in the direction opposite to the device and release the end from the insulation.

The device copes well with multi-core communications, is easy to use and does not require any maintenance. If the cutting sharpness is lost, the blade can be replaced with a new one.

When performing work, you should follow the rules for safe work with power tools, and also be especially careful when installing a thin blade - it is very easy to cut yourself with it.

As you can see, it is not at all necessary to spend money on special devices when you can get an equally effective device for stripping the ends of wiring with your own hands almost free of charge.

    Cool, I need to make something like this, I’m already tired, I cut all my fingers stripping the wires, especially when the insulation has already dried, and I can’t buy a good stripper, I don’t remember what it was called before.

    I worked for 31 years as an electrician, a KIPovets. At the beginning of my career I had a mentor - my grandfather was an electrician, still of the old Soviet school, he stood at the origins of mass electrification of industry (in 1987 he was 60 years old), he started when there were still electric motor starters.there wasn’t, everything was turned on by switches. Once he noticed how I was stripping the ends - this is the mistake of all young electricians - cutting the insulation in a circle. He asked why? But because you cut the core and if not immediately (when twisting, when bending the ring, when bending , if you just need to lead the end, let’s say to the terminal block) it will break, especially aluminum, then perhaps later, during operation. Just use a knife and plan along the wire. Somewhere and now I have these pliers lying around in the shed that can bite the wire and remove the insulation, adjustable for any cross-section up to 10 square. I have never used it.

    I very much doubt that the author made it as he promised in 5 minutes.
    In good offices, the owner makes sure that the workers have quality tools.

    1. Let's start with the fact that if you need to strip the wires 1 time, then fuck this hemorrhage!
    2. If you do electricity, then you have tongs!!!
    3. If an electrician comes to me with such crap, it means his hands don’t grow from there or he’s not an electrician!
    4. If you don’t have 200-300 rubles to buy pliers, then you shouldn’t bother with an electrician!!!!!!!!!!!!!!!
    5. WHY REINVENT THE BIKE????

      What about the process itself?..

    Well, a good cleaning costs more than 300 rubles, but this looks like a good device and simple, I should try it. Respect to whoever came up with it!
