What you will need:
- electric soldering iron 60 W;
- mounting knife blade;
- long M5 bolt.
The process of making a cutter from a soldering iron
The standard tip of the soldering iron must be removed. Instead, you need to install an M5 bolt sawn lengthwise from the side of the head to a depth of 10-15 mm.
It is important to make a thin cut, so it is better to use a hand jigsaw for this.
A broken segment from the mounting knife blade is inserted into the bolt inserted into the soldering iron. Then the cutter is tightened with screws.
Now, when the soldering iron heats up, the blade will very quickly and accurately cut through the plastic without leaving wide beads of melt, as happens when using a hot wire.
Another advantage of such a homemade product is that after work the standard tip returns to its place, and the soldering iron can again be used for its main purpose.
