The Milwaukee M18 FUEL FID3 is built for users who want serious fastening power without carrying a bulky tool. Its short body reaches between joists and inside cabinets while the four-mode drive control helps tame the available torque.

Performance and handling
The FID3 drives long structural screws quickly and has enough reserve for repeated site work. The selectable modes make it easier to move from delicate fixings to large timber screws without relying entirely on trigger control.
At about 113mm long, the head is exceptionally easy to place in restricted areas. The grip is comfortable and the tool feels balanced with a compact battery, although a larger pack is useful for sustained heavy work.
Who is it for?
It suits carpenters, installers, builders and serious renovators already using Milwaukee M18 batteries. Occasional DIY users may not need this level of speed or torque.
Final verdict
The Milwaukee FID3 is one of the strongest compact impact drivers available. Its combination of power, size and useful modes makes it a first-rate professional choice.
