The PH-19VS takes over where the PH-19 reciprocating power hammer leaves off. By adding an inverter drive to an already potent machine, Baileigh Industrial raised the bar again. When precise speed control is needed for those delicate jobs, the PH-19VS shines. Powered by 110 volts, the PH-19VS allows the operator to control the beats per minute from 0 to 1700. The beats are controlled by either a foot pedal or a control box on the side of the machine, it is your choice.
