IWISSFerrule Crimping Tool Kit, AWG 23-10 Self-adjustable Ratchet Ferrule Crimper Plier c/w 770End Sleeve Ferrules Connector Terminals on Electrician, Contractors, Repair Support

Excellent kit for the money. Has a good assortment of sizes.

I spent last night I spent last night going through my kit built 3D printers adding these ferrules to all the screw terminals on the main control board. On the 10 ga wires, crimped ferrules left them slightly too wide to get into the terminal to be clamped, so I had to squish them just a touch with my Knipex pliers wrench to get them to fit in there. I got the crimper that leaves square ferrules because my use will entirely be with screw clamp terminals. The connections are now incredibly solid and I no longer have concerns about the wiring popping loose and causing issues. I had to increase the tension in order to get a crimp that I felt was satisfactory on the bigger ferrules. Even with the lighter setting the crimps felt very solid, but I am a proponent of going overkill when doing anything. Hence my use of massively thick wiring to power my 3D printer and it’s heated bed. The crimper still works great on the smaller ferrules with more tension. Once you install the crimped ferruled wires in the terminals, you get the satisfaction of tugging on the wiring and saying the age old utterance all adult males live to say “That’s not going anywhere”.

Was able to obtain these during Prime Day and therefore got them at a discount. I've been using ferrules for a year or so when dealing with car audio installation. Specifically for amps connections and battery terminal connections. I've been eyeing these for awhile, but never took the plunge. And well...they are definitely well worth it. Gives it a nice clean look...plus they secured. Just wish they made these for larger gauge ferrules.

Great deal. This is a VERY useful tool, essential for small terminations. Feels like very solid quality, and the case is durable.
