Our take on the Milwaukee M18 FUEL 18V 3/8 in. Compact Impact Wrench with 6.0 Ah High Output Battery Pack

The Milwaukee M18 FUEL 3/8 in. Compact Impact Wrench is a brushless 18V cordless tool rated at 251 ft-lb of torque and 2,500 RPM, built for tight spaces where a full-size impact won't fit. It weighs 2.4 lb bare, uses the M18 FUEL GEN-3 platform, and ships here with a 6.0 Ah High Output battery pack. The best new price is $144.98 at eBay as of November 4, 2026, with 4 stores listing it new. That is a low point for this kit, which usually runs closer to $200-$250 with a High Output battery.

Pros
  • 251 ft-lb of torque in a 2.4 lb compact body
  • Brushless motor with REDLINK Intelligence for overload protection
  • 3/8 in. anvil suits most automotive and assembly fasteners
  • 2,500 RPM drives small bolts quickly
  • 6.0 Ah High Output pack adds runtime and fits the whole M18 line
Cons
  • 251 ft-lb is short of mid-torque and high-torque impact wrenches for stubborn lug nuts
  • 3/8 in. drive limits it to smaller sockets; 1/2 in. jobs need an adapter
  • Bare tool is light, but the 6.0 Ah pack adds noticeable bulk
  • No friction ring option on this version; socket retention is pin-detent style

Questions and answers

Is the Milwaukee M18 FUEL 3/8 in. impact wrench worth it?
Yes for automotive and assembly work where space is tight. At $144.98 at eBay as of November 4, 2026, with a 6.0 Ah High Output battery included, it undercuts most kit pricing. If you mostly remove lug nuts, step up to a mid-torque model.
How does it compare with the M18 FUEL 1/2 in. mid-torque?
The mid-torque delivers roughly twice the breakaway torque and takes 1/2 in. sockets, but it is larger and heavier. The 3/8 in. compact wins on access and weight; the mid-torque wins on stubborn fasteners.
What comes in the box?
The wrench and one M18 6.0 Ah High Output battery pack. It is not a full kit, so check whether a charger and case are included before buying.
Will the 6.0 Ah High Output battery fit other M18 tools?
Yes. It works with any Milwaukee M18 tool, and High Output packs are designed to deliver more current to high-demand tools like this one.
When is it cheapest?
Milwaukee promotions cluster around holiday sales and spring tool events. The $144.98 eBay price as of November 4, 2026 is already below typical kit pricing, so waiting has limited upside.
Where is the Milwaukee M18 FUEL 18V 3/8 in. Compact Impact Wrench with 6.0 Ah High Output Battery Pack cheapest?
