Designed for use with 316L Stainless steel, these pliers make working with thicker wire from about 20ga up to and including 12 gauge wire very easy. They do work perfectly with the thinner gauges, but if you work with 20ga or higher I would recommend these pliers as they cut the thicker wire with less effort and still give a nice clean cut. They are larger than the Xuron Micro Flush Cutter available on this site.
