Review on Hitachi 998030 Punch CN16SA Nibblers: Precision Cutting Tool for Smooth and Accurate Results by Robert Dickinson

We cut about 80 linear feet of 65 acre Quadraloc sheet metal before these parts are finished. We go through about 4 of these beats a year. Sometimes we need to cut 26 ga R plate metal and these bits are only enough for 20 linear feet of cutting at 26 ga. It seems like they're meant to be worn longer, but given that everything is made in China these days, it's no wonder they don't perform exceptionally well. I keep buying them because I don't know any better and they work fine for a while :)
