The DM150 is designed for 1-1/4-inch to 4-inch diameter pipes in residential sinks, bathtubs, shower drains, roof vents and floor drains. The DM150 is a powerhouse machine that performs a variety of jobs. The D-shaft motor gives this machine extra torque to help push through an obstruction. Operates in 5 positions (0 to 90 degrees) that can be secured in notched positions to keep the reel from slipping. The DM150 can be transported easily with a machine cart or an optional lifting handle which can be added to the machine. The quick-change reel also allows an operator to switch between two different sized cables in just minutes.
