If you work in a job that requires Phoenix connectors, or friction connections buy this ferrule crimp tool! Just match the appropriate size wire with the correct connectors and you will be golden. Super comfortable to hold (i have small hands) Feels well made no kind of slop in the tool. Easy to use and created a nice strong crimp.
I happened to see a tech use this instead of just using bare wire into a board-mounted terminal block and it looks so much more cleaner and professional. It absolutely does away with the 'rigged up' look you sometimes get with bare wires and terminal blocks.
It makes very secure connections between the metal sleeve and the wire and is completely secure and super easy to use. And since it's square it goes in many terminal blocks and other places.
I had to re-wire my Chinese laser cutter. Most of the internals used those green screw-down terminals. I bought this kit of ferrule connectors/crimper - and I'm glad I did. I put them on everything now!
