Is the DeWalt DCF899 powerful enough for lug nuts?

Yes. At 950 Nm it removes most passenger-car and light-truck lug nuts, and it handles many heavier truck fasteners. For very stubborn bolts, use a fully charged high-capacity battery.

Does the DCF899 come with a battery?

It depends on the version. The bare-tool model ships with no battery or charger, while kit versions include them. Check the listing before buying.

What size sockets does it take?

It has a 1/2-inch square drive, so it uses standard 1/2-inch impact sockets. Do not use chrome hand sockets; they can crack under impact load.

How does it compare to the DCF894?

The DCF899 is the high-torque model at 950 Nm; the DCF894 is a mid-torque wrench around 440 Nm and is smaller and lighter. Choose the DCF899 for heavy fasteners and the DCF894 for general work in tight spaces.

Which battery should I use with it?

Any DeWalt 20V MAX battery works. For maximum torque and runtime, use a 5.0 Ah or larger pack; compact 2.0 Ah packs drain quickly under heavy load.

When is the best time to buy?

Prices tend to dip during holiday sales and when DeWalt runs battery or kit promotions. Compare bare-tool and kit prices, since a kit can cost little more than the tool alone.

Our take on the DeWalt DCF899

The DeWalt DCF899 is a cordless 18V high-torque impact wrench rated at 950 Nm (about 700 ft-lb) of maximum torque. It is built for heavy fastening: lug nuts, suspension bolts and structural hardware. It uses DeWalt's 20V MAX battery platform (sold as 18V in some markets) and comes in bare-tool and kit versions. It is a large, heavy tool aimed at mechanics and trades, not light home use.
