For uninsulated but unfortunately not. The crimp is simply not accurate. And neither the executive nor the strain relief. The connector slide down in train from the cable. As a universal electric tongs is probably technically simply not suitable for the (demanding) crimping uninsulated, open connectors.
Right I was disappointed with the device for cable stripping. The blades are not focused properly, or it was just not precise enough ground. Partly still adheres metal loops from where it was supposed to be sharp. Clean stripping unfortunately not possible.
