The Milwaukee 49-16-3049 protective boot is a lightweight, form fitting cover designed for the M12 FUEL subcompact impact wrenches 3049-20 and 3048-20. It protects both the tool and work surface while adding minimal size or weight. The proprietary rubber compound resists oils, solvents and corrosive materials commonly found in maintenance environments. Its flexible construction allows easy installation and removal without tools, supporting quick cleaning and inspection. The boot is engineered specifically for these models and is not intended for use with other impact wrenches. Built for professional technicians, it provides long lasting protection in demanding shop and field conditions.
