Ratchet crimper

[Andy78]

no, ive tried it with through crimps and they split them.

Cheers, I thought that might be an issue. I'll stick with the clunky long arm crimper until I see something better then.

Are the Knipex and Haupa ones pictured in this thread any good for copper lugs, or just really suitable for ferrule ends ? I'm looking for a more compact tool for lugging onto earthing and bonding cables up to 16mm and these look as if they might do.

For copper tube lugs you really want something with mechanical advantage/leverage.

ive got a set of knipex ferrule pliers

cost me £20 and go from 0.25-16mm

my lasy ck set only went upto 2.5 but the knipex go lower lol

Have you tried them on .25?, I do a fair bit on .25/.34 and find some crimpers don't live up to the specs and give me a loose ferrule I can pull the wire out.

Cheers Tel, those look the business and cheap too. They are a hex crimp die right ?

I've been stuck with one of these type for ages and they are a right pain to use for lugs so small. Very inexact and not really a suitable die shape.

sorry i havent tried it on .25 but i havent had a loose one yet (if you need to the very ends are pliers so could always give them a squeeze)

we tend to use 0.75 minimum upto 6mm depending on the length of run

Nice and easy to use, when set right the hydraulics "break" at the correct crimp pressure so a perfect crimp every time.

Thanks, I tend to mainly work on .25 to 2.5, panel builds & signal wiring.

Cheers Shanky but I'm just after something small for my domestic work.. those are a bit overkill. I have used those hydraulic type before and they are amazing, the set I used cost a fair bit more than that though.

Place I worked at had a set of these for uninsulated crimps up to 16mm² they worked fine.
