    Best Crimper

    Posted by L. T. on Sep 15th 2020

    Exactly what I needed, no more no less. Used it to make custom 8.5mm wires for my FXD. Stripper stripped the shielding perfect and the crimper did as well. I saw other tools that were twice the price. If you need to do what I did, buy these you won't regret it.

    What can I say?
    It’s just a crimper. Does its job and otherwise sits at the bottom of the tool chest ….
