Questions and answers

Is the Milwaukee M18 FUEL 3/8 in. impact wrench worth it?
For auto and general repair work in tight spaces, yes. It delivers up to 250 ft-lbs of nut-busting torque in a compact body and comes with two 6.0 Ah batteries and a charger.
How does the GEN-3 compare with earlier M18 FUEL versions?
The GEN-3 is the current generation, with updated electronics and the same compact footprint. If you already own an older version, the gains are modest; new buyers should get the GEN-3.
