Which is better for lug nuts on a car?

The DeWalt's 400 ft-lb breakaway rating gives it more headroom for seized fasteners. The Milwaukee's Bolt Removal Control makes it easier to avoid dropping nuts once they break loose.

Do I need to buy a battery for the DeWalt?

Yes. The DCF903B is a bare tool, so budget for a 12V Max battery and charger unless you already own them. The Milwaukee listing includes an M18 battery pack.

Is the Milwaukee worth the extra $4.71?

At $110.00 versus $105.29 at eBay as of November 4, 2026, yes for most shoppers. You get a battery, four drive modes and a much larger rating base for about the price of a fast-food lunch.

Which is more compact?

The Milwaukee is 4.8 in long. The DeWalt is listed at 2 lb with no published length, so check the head length if clearance is your main concern.

Both use brushless motors. The Milwaukee adds REDLINK PLUS overload, overheating and over-discharge protection, which helps battery and tool life under hard use.

Can I use my existing DeWalt 12V batteries in the Milwaukee?

No. The DeWalt runs on 12V Max batteries and the Milwaukee on M18 18V packs. Neither accepts the other brand's batteries.
