Toolwiz Battery Cable Lug Crimping Tools 6-50mm² Ratchet Wire Cutting for Crimper Tool Terminal Wire Cable from AWG 1/0, 2, 4, 6, 8, 10 -Thickened and Reinforced The Metal Plate

Wasn't expecting miracles at this price, however build quality it very good, smooth operation when using/crimping, and not overly big either so can be stored in a tool chest.

Unlike other poor comments, I have no complaints. Use the correct size terminal for correct size wire and it all holds good and tight.Very happy

Certain lugs it doesn't work properly on and they are left loose.

These work OK, but say you need to crimp a 50 lug, you need to use the next size down, els it's not clamped enough.

Top tool

Unfortunately I did not use the tool until after my return window lapsed, otherwise i would have sent it back. It feels sturdy enough but the numbering on the crimp dies is hard to read and more importantly, it does not crimp the terminals very well at all. When squeezed together the terminal goes way out of shape and looks awful. Every single time, the terminal squeezes through the top part of the die, creating a pinched bit of metal and it does not hold the cable very well. I am disappointed with this purchase and should have tested it sooner. I have wasted my money on this tool.

As others have said, I too have found it doesn't crimp tightly. I have tried different crimps on 16mm2 and 25mm2 cables, both flex and solid core and the result is always that it isn't tight. I have resorted to using the setting for one size down, but this mangles the crimp badly and looks awful.

I bought these to use with Krafton 25mm2 lugs and MKGT 25mm2 cable (both from Amazon). Lugs are heavy and good quality, cable goes in the end with minimum slack but on the 25/25 setting these just do not work, they "tickle" the lug but you could pull it off without any effort. Next crimp size down is 16/16 and it works but deforms the lug far too much. I figured by using a 16/25 combo and watching the crimp carefully then turning the lug 90 degrees I could get it to work well without deforming the lugs and leaving any compression ridges....Remember to pay attention to the thorough instructions on the handle, which I have kindly replicated for your benefit-1/The pressure meet terminal must select and use appropriate terminal specification first being put into use coordinating the correct implement again when being put into use.2/Revolution retinue pressure model arrives at correct location.3/Retinue pressure model specification must be going to identical, to need Pingqi who plasec.4/Pay attention to the original place placing the latch be obliged to, can be put into use just now.5/Do not fall again please.Happy crimping!
