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 Head is designed to produce high amplitude vibrations to remove air pockets from the concrete and evenly distribute aggregate, resulting in higher quality concrete. The Concrete Vibrator Head is for use with the MILWAUKEE® MX FUEL™ Briefcase Concrete Vibrator and the MILWAUKEE® MX FUEL™ Backpack Concrete Vibrator. 4 sizes are available, which are 25mm (1"), 38mm (1-1/2"), 50mm (2") and 64mm (2-1/2").
