I had this special pliers to crimp contacts for small AWG28-24 lines ordered (not Amazon). Unfortunately, I realized that just does not work, because the die set is made much too imprecise. In particular, the support surface for the contact base is too narrow, so that the material is pressed against both sides of the support surface by, rather than being at the top right bent and compressed. From 10 Crimpversuchen was just a single successful. It may be that the forceps for greater contacts works better - as the die set looks, you can also imagine that there are major quality variations here and perhaps with another copy has better luck. But I have no desire to further Porto to spendieren to try this.
