The DeWalt DCF891N is a mid torque half inch impact wrench that sits between compact wrenches and the heavy DCF900. It lists 600 ft-lb of fastening torque and 800 ft-lb of breakaway torque, which is roughly 813 Nm and 1,085 Nm. With four speed settings and a compact body, it suits mechanics and fitters who want strong output without a bulky tool.

Our take
Torque in context
DeWalt quotes its figures in foot pounds: 600 ft-lb fastening and 800 ft-lb breakaway. Converted, that is a little over 800 Nm and 1,000 Nm. Those numbers cover wheel nuts, suspension bolts, subframe fixings and most site anchors with plenty in reserve.
A brushless motor is listed, and DeWalt describes the design as compact and lightweight for tight spaces. The listing gives a weight of 1.67 kg.
Four speeds and Precision Wrench
Four speed settings and a variable speed trigger let you choose the output level for each job. Precision Wrench control is listed to help prevent overtightening and stop fasteners running off when you reverse them out. Together, those make the DCF891N more forgiving on smaller fixings than an all out high torque wrench.
Hog ring anvil
The half inch hog ring anvil holds sockets with a spring ring, so you can swap them by hand. That is quicker than a detent pin and suits jobs where you change sizes often. An on tool LED light is listed for dark wheel arches and engine bays.
Hog rings do loosen over time with heavy socket changes, so it is worth checking the ring now and then and replacing it if sockets start to drop off.
What you need to add
This is a bare unit. You will need DeWalt 18 V XR batteries and a charger, which makes it most attractive to existing DeWalt users. The listing does not include a case.
If you are new to DeWalt, a 5.0 Ah XR pack is a sensible pairing for a wrench of this size, as it gives enough runtime for a full set of wheels and several suspension jobs between charges. Smaller packs keep the tool lighter but will need swapping more often.
Against close rivals
The DeWalt DCF900P2T is the bigger brother with far more torque and a full kit. The Milwaukee M18FIWF12 offers a friction ring half inch wrench for M18 owners. The HiKOKI WR36DH is lighter with auto stop and auto slow, but lower breakaway torque.
Verdict
The DCF891N is a well balanced choice for DeWalt XR owners who want plenty of torque in a compact half inch wrench with speed control. If you need maximum breakaway force, the DCF900P2T kit is the step up, and Milwaukee M18 users should compare the M18FIWF12.
