Performance
Physical & Build
The M18 FID3 is Milwaukee's current Gen4 FUEL impact driver, a brushless 226Nm tool with four drive modes and a fast 4400 impacts per minute, in a compact 113mm body with the POWERSTATE motor. It sits at the top of the M18 driver range. We rate it the flagship pick for M18 owners; the previous Gen3 FID2 matches it on torque, and the brushless BLID2 is the lighter-duty option below.
