Concrete Vibrator Shafts are designed to transfer power from the motor to the concrete vibrator head. These shafts offer superior durability and productivity. The all-metal coupling prevents melting and deformation throughout the shaft's life. All Milwaukee shafts feature a quick connect system that allows you to quickly and easily attach and detach the shaft. The Concrete Vibrator Shaft is for use with the MILWAUKEE® MX FUEL™ Backpack Concrete Vibrator and are available in 7 ft and 14 ft sizes.
