A Two Speed Drill Motor make a wide range of speeds available when using variable flow power units. Speed change can be carried out in seconds by a push / pull actuator on the motor, which effectivly doubles the out-put speed. You can choose whether you want a On/Off valve with the motor and if you want a Water Swivel.
Two speed drill motors allow an operator to drill through a top layer of asphalt at the higher optimum speed of 6m/s and quickly switch to the lower optimum speed 3m/s when reaching concrete material underneath.
