MX FUEL™, Milwaukee®'s new equipment system, goes beyond the limitations of petrol and corded units, utilising the industry's most advanced batteries, motors, and electronics to deliver the best experience for users. This is equipment, redefined. The MX FUEL™ Concrete Vibrator Flex 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 users 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 2.1M (7 ft) and 4.2M (14 ft) sizes.
