Our 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 shafts life. All Milwaukee shafts feature a quick connect system that allows you to quickly and easily attach and detach the shaft. The Concrete Vibrator Shafts are for use with our MX FUEL Backpack Concrete Vibrator (MXF371-2XC) and MX FUEL Concrete Vibrator (MXF370-2XC and are available in 7 ft and 14 ft sizes.
