Cordless Drills guide · 2018 release

Milwaukee M18 Fuel 2804-20

Buy used when the drill is tight, the chuck is true, and the battery deal is real.

The 2804-20 still lands in the sweet spot for power and battery-platform value, but used pricing only works when wear on the chuck, gearbox, and pack fit stays under control.

This Milwaukee hammer drill still makes sense used because the platform is liquid, the tool is capable, and replacement accessories are easy to source. The main risk is paying near-new money for a hard-used body with battery or chuck wear hiding behind cosmetic cleaning.

Reasons to buy used

Platform batteries and accessories are easy to find.
Bare-tool resale is liquid enough to be selective.
Performance is still strong for general drilling and fastening.

Reasons to buy new

Near-new pricing narrows the savings fast.
Fresh warranty coverage matters if the tool will see heavy jobsite use.
Battery bundle math can beat bare-tool used deals when promos are active.

Check 1

Check for chuck wobble with a long bit installed.

Hard-used tools sold as “lightly used.”

Near-new pricing narrows the savings fast.

Check 2

Run through both speed ranges and confirm clean shifting.

Worn chucks that slip under load.

Fresh warranty coverage matters if the tool will see heavy jobsite use.

Check 3

Listen for gearbox grind under load.

Battery-platform costs hidden behind a cheap bare-tool listing.

Battery bundle math can beat bare-tool used deals when promos are active.

Check 4

Verify battery fit is tight with no intermittent power cut.

This is one of the fastest ways to separate a real used bargain from a polished listing.

If this check fails, the used discount is usually not strong enough to keep the recommendation where it is.
