This POWER-VEE unit is designed as a miniaturized version of our big machine power cable feed, giving you speed and convenience that you've never seen in a hand held machine. In tight or awkward places, the POWER-VEE is like having an extra hand. This unit is designed to clear clogged drains from 1-1/4 in. through 2 in. Dia. The unique Dyna-Thrust bearing system is 1 of the features built into this unit that will allow it to last a decade or more. It helps carry the weight of the drum, significantly reducing wear on the motor shaft bearing and extending the life of the tool. Of course the cables are Flexicore-with an integral wire rope center. Nobody makes cables like General.
