    No 10-12 die for flag terminals

    Does wirefy make a 10-12 flag terminal for the crimper?

    Terminals got stuck in die C

    I bought the Wirefy crimper set a few months ago and used it for the first tim today on 2.8mm female spade open barrel terminals using the smallest die "C" opening. While the crimps were adequate, the terminals got stuck in the die every time and had to be pried loose. I've never had that problem before with an open barrel crimper, and I suspect a design flaw in the die. Overall, the crimper seems to be good quality and ruggedly made, and I like the way the dies interchange.


    Easy to change and snug fit


    First time that I crimped fitting and didn't have to redo it.
