The Wheeler-Rex Hole Cutter System is designed to easily cut holes from 4"–12" (100–300mm) into clay tile, ductile and cast iron, plastic and reinforced concrete pipes. The unit is available with a variety of power sources including 2-cycle gasoline engine, pneumatic motor, electric motor and hydraulic motor. The system is modular in design which allows a single operator to set up and perform non-pressure taps safely and quickly. The basic system can be used on pipes from 6"–20" (150–500mm) O.D. and the capacity can be extended by simply adding chain to the hold down mechanism. Set up normally takes 5–10 minutes and actual cutting time is 5–10 minutes depending on pipe material and wall thickness.
