Strengths & Weaknesses

Milwaukee M18 FUEL 1/2" Hammer Drill/Driver

+ Strengths
  • Highest working torque of any drill tested (455 in-lbs), per Project Farm's dyno measurements
  • Won John Malecki's destructive "fight to the death" bracket against 16 other brands
  • Most compact heavy-duty drill at 6.9 inches front-to-back, per Project Farm
  • All-metal ratcheting chuck with carbide teeth grips at 178 in-lbs, per Project Farm
Weaknesses
  • Costs nearly 3x the Hercules value pick, per Pro Tool Reviews
  • Measured 95.9 dB under load, one of the loudest tested, per Project Farm
  • Aggressive vibration and wrist fatigue during sustained heavy use, per Project Farm
Key flaw: The price is the obvious weakness.

Hercules 20V Brushless Compact Hammer Drill/Driver

+ Strengths
  • All-metal ratcheting chuck grips at 159 in-lbs, beating the much more expensive DeWalt, per Project Farm
  • Drove 5-inch lag bolts in 5.82 seconds, only fractions behind the Milwaukee, per Project Farm
  • Completed the same heavy-duty hole saw tests as flagship drills for a third of the price, per Pro Tool Reviews
  • 5-year warranty from Harbor Freight's Hercules line
Weaknesses
  • Clutch is broken: 47 in-lbs on the lowest setting makes precision fastening impossible, per Project Farm
  • Triggered overload shutoff during sustained 2-9/16" hole saw test, per Pro Tool Reviews
  • Housing blew open during John Malecki's drop-test tournament; internal build lags behind the speed performance
Key flaw: The clutch is genuinely bad.

The Verdict

Our Bottom Line

The Milwaukee M18 FUEL 2904-20 wins because it tops every measurable metric that matters for a drill. Project Farm's dyno testing measured 455 in-lbs of working torque, the highest of any model tested, and it drove 10-inch lag bolts faster than drills costing 20% more. Pro Tool Reviews ran it through aggressive self-feed auger bits and 2-9/16" hole saws where cheaper drills stalled or triggered thermal shutoffs. The Milwaukee never flinched.

Best for:
  • Tradespeople and contractors who use a drill daily and need zero downtime
  • Home renovators tackling structural work like deck framing, lag bolts, and concrete anchors
  • Anyone already invested in the Milwaukee M18 battery ecosystem
  • Users who need precise low-torque clutch control for both heavy boring and delicate fastening
  • Overhead workers who value the 6.9-inch compact body for joist bays and tight framing

The Hercules 20V earns the value crown by doing something no $80 drill should: keeping pace with tools that cost three times as much. Project Farm timed it at 5.82 seconds on the 5-inch lag bolt test. The Milwaukee finished in roughly 5.5 seconds. That gap is negligible for anyone outside a timed competition.

Best for:
  • Weekend DIYers building furniture, shelving, or doing moderate home repairs
  • First-time power tool buyers who want real performance without the pro-tier commitment
  • Budget-conscious renovators whose heaviest tasks are drilling pilot holes and driving deck screws
  • Harbor Freight shoppers who already own Hercules 20V batteries from other tools
  • Anyone who can live without precision clutch control and just needs raw drilling muscle
