CarCareTruth's Analysis

Last reviewed May 17, 2026

TL;DR Mid-range cordless ½" wrench (600 ft-lbs fastening / 800 ft-lbs breakaway per manufacturer) on DeWalt 20V MAX; no independent US safety certification confirmed.

What it is and how it performs

Brushless cordless ½" hog ring impact wrench rated at 600 ft-lbs fastening and 800 ft-lbs breakaway torque. Runs on DeWalt 20V MAX batteries (200+ compatible tools). Weighs 4.3 lbs with 4-speed modes for precision fastening control. No independent torque meter test was located; community evidence draws from fastener-removal outcomes only. Amazon corpus (4.8★, 2,135 reviews) shows no stall-out pattern on standard passenger-car and light-truck lug nuts. Electric — no air compressor required.

Who should buy this — and who should skip it

Home mechanics doing tire rotations and light under-car work on passenger vehicles already on the 20V MAX platform will find this capable and convenient. Skip it if your primary use is heavy-duty truck wheel studs or seized suspension bolts — a higher-torque model with community-confirmed 700+ ft-lbs real-world output serves those better.

Safety and environmental impact

No UL or ETL certification confirmed as of 2026-05-17. Li-ion battery; no documented thermal incidents. Hearing protection situationally appropriate for extended use. Standard e-waste disposal; Call2Recycle handles the battery pack.

Frequently asked questions

Does the DEWALT DCF891B come with a battery?▾

No. The DCF891B is a bare tool — it includes the impact wrench and a belt clip only. A compatible DeWalt 20V MAX battery and charger are sold separately. The wrench works with any DeWalt 20V MAX battery across the platform's Ah options.

Can the DCF891B remove lug nuts on trucks and SUVs?▾

Community evidence from Amazon verified-purchase reviews supports reliable lug nut removal on standard passenger vehicles and light trucks. No independent calibrated torque meter test was located — the 600 ft-lbs fastening / 800 ft-lbs breakaway spec is from the manufacturer. For heavy-duty truck wheel studs or severely seized suspension bolts, consider DeWalt's higher-torque DCF899B (700 ft-lbs fastening) or a model with community-confirmed 700+ ft-lbs real-world output.

Is the DEWALT DCF891B UL-listed?▾

No independent US safety certification (UL or ETL) was confirmed for the DCF891B as of 2026-05-17. The UL Product iQ lookup was inconclusive for this model number, and the Amazon listing does not state CE certification. The health score reflects a certification deduction.
