Our take on the DEWALT DCF99M 20V Brushless Cordless Impact Wrench, 1/2" Drive High Torque Power Tool

The DeWalt DCF99M is a 20V Max brushless cordless impact wrench with a 1/2-inch square drive, built for high-torque fastening on lug nuts, suspension bolts and heavy machinery. It sits in DeWalt's high-torque tier, above the compact mid-torque wrenches, and competes with Milwaukee's M18 Fuel high-torque and Makita's 18V XWT models. The brushless motor and 20V battery platform suit buyers already on DeWalt packs; the trade-off is size and weight against compact wrenches. Reviewers of this class of DeWalt high-torque wrench praise breakaway power and battery life, and note the bulk and cost of batteries as downsides.

What reviewers say

Owners of DeWalt high-torque 20V impact wrenches report strong breakaway power on lug nuts and suspension hardware and good runtime per charge. Common complaints are the weight and size in tight spaces, and the added cost of batteries and a charger when bought as a bare tool.

Questions and answers

Is this a high-torque or mid-torque impact wrench?
It is a high-torque 1/2-inch drive wrench, the larger tier in DeWalt's 20V line. It is built for lug nuts and heavy fasteners rather than light assembly work.
Does it come with a battery and charger?
It is commonly sold as a bare tool, so check the listing for what is included. Most buyers need a DeWalt 20V Max pack and charger separately.
What size sockets does it take?
It uses a 1/2-inch square drive, so standard 1/2-inch impact sockets fit. Use impact-rated sockets, not chrome hand sockets.
How does it compare with the compact DeWalt impact wrenches?
It delivers more breakaway torque than the compact and mid-torque models but is larger and heavier. Choose the compact if you mostly work in tight spaces.
Is it good for home garage use?
It is more wrench than most home jobs need, but it handles lug nuts and suspension work with ease. Casual users may prefer a lighter mid-torque model.
