DeWalt's New High-Torque Impact Wrenches: 3/4-Inch and 1/2-Inch Models Worth a Look

Introduction

DeWalt has added two high-torque cordless impact wrenches to its 20V lineup, and the claimed numbers are genuinely eye-catching. A 3/4-inch drive model with up to 1,900 ft-lbs of breakaway torque sits at the top, while a 1/2-inch drive version brings 1,775 ft-lbs of breakaway torque in a slightly smaller package. Both were announced with a pre-sale window and are now rolling out to retailers.

If you are already invested in the DeWalt platform, these are worth a serious look. Here is how the two impact wrenches compare and where each one makes sense.

DeWalt DCF964B 3/4-Inch Impact Wrench

The DCF964B is the flagship of this release, and its specs back that up. DeWalt claims 1,900 ft-lbs of breakaway torque, 1,420 ft-lbs of max fastening torque, and an impact rating of 2,015 impacts per minute. The tool uses a hog ring retention on the 3/4-inch anvil, and the claimed power figures put it in contention for the most powerful impact wrench on the market.

This is the tool you reach for when you need to break loose seriously stuck fasteners, the kind of hardware that smaller impact wrenches cannot touch. Think heavy equipment, agricultural machinery, and large-scale automotive work.

The DCF964B sells for $399 as a tool-only unit. A kit version with the new 5Ah oil-resistant PowerStack battery is priced at $529.

DeWalt DCF961B 1/2-Inch Impact Wrench

The DCF961B packs nearly as much claimed power into a smaller, more versatile package. It offers up to 1,775 ft-lbs of max breakaway torque and 1,200 ft-lbs of max fastening torque, which DeWalt positions as up to 71% more torque for tough fastening applications. The weight comes in at 8.42 lbs, and it uses a hog ring on the 1/2-inch anvil.

At 8.42 lbs it is not a lightweight, but the 1/2-inch drive makes it far more practical for everyday shop work, general repair, and most automotive tasks. If you only need one impact wrench, this is the more flexible choice.

The DCF961B is available now, with the tool-only version at $369. The kit variant runs $499, which is only slightly cheaper relative to the kit savings on the larger model.

Kit vs Tool-Only: Which Way to Buy

DeWalt is bundling these wrenches with a new 5Ah oil-resistant PowerStack battery. The oil-resistant pack is a notable detail for anyone working around grease, oil, or solvents, and it appears to be a newer addition to the battery line. Whether you go kit or tool-only comes down to whether you already own good batteries.

One tip worth noting: at the time of release, DeWalt was also running promotions with a free 5.0Ah two-battery starter kit on qualifying purchases. Those batteries are standard packs, not the PowerStack, but they can be a way to expand your battery collection without spending more.

Buying Advice

For most buyers torn between the two, the 1/2-inch DCF961B is the smarter first purchase. Its torque output is close to the 3/4-inch model, it weighs less, and the 1/2-inch drive suits a wider range of sockets and fasteners.

The 3/4-inch DCF964B is a specialist tool. If your work involves tank tracks, large machinery, or seriously rusted heavy hardware, the extra torque and larger anvil justify the higher price and weight.

Whichever route you choose, consider the tool-only version if you already have a healthy battery stock. Kit prices make sense mainly when you want the new oil-resistant PowerStack pack specifically.

Conclusion

DeWalt’s new impact wrenches bring claimed numbers that stand up well against the competition, with the 3/4-inch model leading the market on breakaway torque and the 1/2-inch offering a more practical daily driver. Check current deals before you buy, since promotional starter kits and battery bundles were active at launch and can meaningfully change the value equation.
