The SPIN tools fit into into any type of electric drill or screwdrivers, as long as it meets the mininum requirements of power and rotation. As the SPIN tools require good rotation rates, we advice for chosing power tools with a minimum of 1,800 RPM, for the best results. As for watts, we recommend using

1) Precision: the flares will always have the same size and will fit perfectly; the swages present a perfect depth and a tight fitting, that will make the brazing easier and will reduce the fatigue stress over the coupling area; 2) Quality: the flare/swage will keep its malleability, which will ensure better couplings overall; the
