QE Quality universal 5 piece copper pipe swaging tool drill bits are a revolutionary system for molding tubes using heat by friction. This allows for more surface between the flare and the valve. The flare will always have the same size and will fit perfectly. The swages present a perfect depth and tight fitting, that will make the brazing easier, reducing the fatigue stress over the coupling area.
Kit includes: 5 Drill Bit Sizes 1/4″, 3/8″, 1/2″, 5/8″, and 3/4″
