Choose the DCF891 for a lighter mid-range wrench, or the DCF900 for higher fastening and breakaway torque. In this DeWalt DCF891 vs DCF900 comparison, the main choice is between lower tool weight and more torque.

The DCF891B is listed at 4.3 lb and delivers 600 ft-lb max fastening torque and 800 ft-lb max breakaway torque. The DCF900B is listed at 6.4 lb, with 1030 and 1400 ft-lb, respectively.

Both have 1/2 in drives, 4-mode speed settings and Precision Wrench control. The DCF900P1 is the kit version, with a 5.0 Ah battery and charger included.

DeWalt DCF891 vs DCF900: which should you choose?

Choose the DCF891 for a lighter tool with mid-range output, and the DCF900 when the job calls for its higher torque figures. The stronger model weighs more, so extra power comes with a handling tradeoff.

The DCF891 lists 600 ft-lb of max fastening torque and 800 ft-lb of max breakaway torque. DeWalt gives the DCF900 1030 ft-lb max fastening torque and 1400 ft-lb max breakaway torque.

Those numbers describe different kinds of output. Fastening torque is the stated figure for driving a fastener, while breakaway torque is the stated figure for loosening one.

If you mostly work with wheel lugs and similar jobs, consider the tool's weight and control as well as its torque. Our guide to how much torque you need in an impact wrench can help you match the wrench to your fasteners.

How different are their torque figures?

The DCF900 has 430 ft-lb more max fastening torque and 600 ft-lb more max breakaway torque than the DCF891. Those are manufacturer-stated maximums, not a promise that either wrench will loosen every fastener.

The DCF891's 600 ft-lb fastening figure is enough to make it a serious mid-range model. Its 800 ft-lb breakaway figure gives it room for jobs that need more loosening force than a smaller wrench can offer.

The DCF900's 1030 ft-lb fastening and 1400 ft-lb breakaway figures put it in DeWalt's high-torque tier. That extra output can matter for large fasteners and demanding work, but it does not replace correct setup or torque measurement.

Fastener condition, joint design, access and the battery can all affect the work. For wheel jobs, use the vehicle manual's torque specification and finish with a torque wrench.

Read our guide to impact wrench torque figures for help interpreting stated numbers.

DCF891 vs 900 for stuck fasteners

The DCF900's higher breakaway figure gives it the advantage on paper for stubborn fasteners. Still, a damaged or seized fastener may need another approach, and an impact wrench can damage threads or surrounding parts if used without care.

Start with the correct socket and a stable tool position. Stop if the socket slips or the fastener begins to round.

Is the DCF891 easier to handle?

The DCF891B is the lighter choice, at 4.3 lb compared with 6.4 lb for the bare DCF900B. That difference can matter when you hold the tool out in front of you or work in a cramped space.

The DCF891 is also described as compact and lightweight for tight spaces. Its listed length is 8.88 in, while the DCF900B is 8.43 in, so length alone does not tell you which will fit your hand or work area better.

Try to account for the battery you plan to use, since the tool figures don't include one. The DCF900P1 kit's listed weight is 11 lb, and that package includes a battery, charger and bag.

If smaller size and easier positioning matter most, see our DeWalt DCF891 review. For a broader look at what separates these tool classes, read mid torque vs high torque impact wrenches.

What control features do both models share?

Both models offer 4-mode speed settings, a variable speed trigger and Precision Wrench control. These features give you options for adjusting output and help reduce overtightening in forward or fastener run-off in reverse.

The DCF891 describes its settings as 4 speed settings. The DCF900 uses 4-mode speed settings and also offers LED brightness adjustment.

Neither model's control features replace a torque wrench for final tightening. Use the impact wrench for removal or running fasteners down, then verify the finished torque with the right tool and the vehicle's specification.

For more about how settings affect fastening, see whether impact wrenches have torque settings. The term “Precision Wrench” describes a control feature, not a way to set an exact final torque value.

Should you get the DCF900B or DCF900P1 kit?

Choose the DCF900P1 if you need the included 5.0 Ah battery, charger and kit bag; choose the DCF900B if you want the tool only. Both are DCF900 high-torque options with the same stated 1030 ft-lb fastening and 1400 ft-lb breakaway figures.

The DCF900B package includes the impact wrench, with the battery and charger sold separately. It also includes battery guard, a shock-absorbing connection between the battery and tool.

The DCF900P1 kit includes a DCF900B wrench, a 5.0 Ah battery, charger and kit bag. If you already own compatible batteries and a charger, the tool-only option avoids buying another set.

Check the exact package name before choosing, since the DCF900B and DCF900P1 are different purchase configurations. The wrench's output class is the same, but the kit contents are not.

Which DeWalt wrench fits your jobs?

Pick the DCF891 for a lighter mid-range tool, and pick the DCF900 when you need its higher output or want the kit package. Your usual fasteners and time spent holding the wrench should guide the choice.

Choose the DCF891B if the 4.3 lb listed tool weight, compact design and 600/800 ft-lb torque figures suit your work. It is a bare tool, so plan for a compatible battery and charger.

Choose the DCF900B if the higher 1030/1400 ft-lb figures fit your heavier jobs and you already have a battery and charger. Choose the DCF900P1 if you want the same high-torque wrench with a 5.0 Ah battery, charger and kit bag.

If you are still deciding between tool classes, compare the options in our best mid-torque impact wrench guide and best high-torque impact wrench guide. For this matchup, the decision rule is simple: favor the DCF891 for lower weight, or the DCF900 for more torque.

Frequently asked questions

Is the DCF891 stronger than the DCF900?

No. The DCF900 has 1030 ft-lb of max fastening torque and 1400 ft-lb of max breakaway torque, compared with 600 and 800 ft-lb for the DCF891.

The DCF891 is the mid-range option, while the DCF900 is DeWalt's high-torque choice among these models.

Which DeWalt wrench is lighter, the DCF891 or DCF900?

The DCF891B is listed at 4.3 lb, while the bare DCF900B is 6.4 lb. The DCF900P1 kit is listed at 11 lb and includes a battery, charger and bag, so compare the bare tools if weight is your main concern.

Does the DCF900P1 kit include a battery and charger?

Yes. The DCF900P1 kit includes a 5.0 Ah battery, charger and kit bag along with the DCF900B wrench.

The DCF900B tool-only version and DCF891B bare tool do not include a battery or charger.

Can you use either wrench to tighten lug nuts?

Both models are 1/2 in impact wrenches and include wheel lugs among their stated applications. Use the impact wrench to remove or run down fasteners, then tighten to the vehicle maker's specification with a torque wrench.
