Tools: Crimp terminal & wire stripper revolution?

I’ve bought a lot of these over the years, and I really think these two are the top choices.

If you’re having trouble getting a clean crimp or things just aren’t coming out right, give this a try.

WEICON Insulated wire stripper No.5 51000005

It handles a wide range of wire diameters—from thin to thick—and can strip them all.
It easily handles anything from about 0.5 to 3.0 SQ.
*I’ve confirmed it works on outer diameters from 1.12 to 3.54 mm.

It can’t strip the middle of a wire, so you’ll still need a conventional stripper as well, but…

I do about 98% of my wire stripping with this one.


When I research things to write about on the blog, I end up discovering… so many new tools (similar ones too) that I start wanting them all.

IWISS ratchet-style crimp terminal and faston terminal precision simultaneous crimping pliers with EDM-machined dies, 1.5–6.0 mm² compatible HS-03BE

I got my hands on this crimping plier.

So what makes choosing a crimping plier so difficult?
• Terminal sizes and manufacturers vary
• The wire diameters you use also vary

It would be really helpful if there were clear specifications saying “crimp this SQ to about this width,” but it’s not that simple.

I measure OEM harness terminals with calipers.

Then I run that wire through the crimping plier and check the clearance to figure out “this terminal goes with this one.”
I could also do a test crimp and measure it, but surprisingly, you don’t find many that end up the same.

Since it has a good reputation, I ordered one and tried it out, and I thought, “Wow, this is a sharp tool!” So I’m introducing it to you.
