Which has more torque, the DeWalt DCF510B or the Milwaukee 2457-21?

The DeWalt DCF510B has 75 ft-lbs, more than double the Milwaukee's 35 ft-lbs. Choose the DeWalt for rusted or high-torque fasteners.

Is the Milwaukee 2457-21 worth it over the DeWalt?

Yes for most home and light automotive work. At $78.57 it includes a battery and charger, while the DeWalt is $199.00 at Walmart as of November 3, 2026, with no battery.

Which is better for tight spaces?

The Milwaukee. It is 10.75 in long and 1.9 lbs, against 15 in and 2.6 lbs for the DeWalt.

Do I need to buy batteries for the DeWalt DCF510B?

Yes. It is a bare tool, so you need a 20V MAX battery and charger unless you already own them.

Which lasts longer on a charge?

The DeWalt runs on 20V MAX packs, including 5 Ah, so it gives longer runtime than the Milwaukee's 1.5 Ah M12 battery. The Milwaukee kit charges in about 30 minutes.

Can the DeWalt use both 3/8 and 1/2 inch sockets?

Yes. It ships with interchangeable 3/8 in and 1/2 in square drive anvils. The Milwaukee is 3/8 in only.

Buy the Milwaukee 2457-21 if you want a ready-to-use kit at a low price; it is $78.57 at the low end of its recent range, far below the DeWalt's $199. Buy the DeWalt DCF510B if you need 75 ft-lbs of torque, both 3/8 and 1/2 inch drives, and already own 20V MAX batteries. The Milwaukee is the better value for light automotive and home work; the DeWalt is the stronger tool for stubborn fasteners.
