SKU : WOR-TOO-111
The DEWALT DCF894B is a 20V MAX XR brushless 1/2-inch mid-range cordless impact wrench designed for serious fastening work. With up to 330 ft-lbs of torque, a lightweight design, and DEWALT's Precision Wrench Control, this bare tool is a must-have for automotive repairs, equipment assembly, and heavy-duty projects.
The DCF894B features a DEWALT-built brushless motor that delivers greater efficiency and runtime than brushed models. Its 3-mode speed/torque selector lets you match the tool to the job—from precision fastening to full-power breakaway.
These settings are approximate and help you avoid overtightening on delicate assemblies.
In forward, the tool pauses before impacting to prevent overtightening; in reverse, it slows down when the fastener breaks loose to prevent run-off. This is a critical feature when working on aluminum or plastic components.
At just 3.48 lbs, this impact wrench reduces fatigue during long jobs. The variable speed trigger and 3,100 IPM ensure rapid work when you need it.
Perfect for professional mechanics, DIYers, and anyone who needs a reliable, mid-range impact wrench for wheel lugs, pipe flanges, and concrete anchors.
330 ft-lbs Max Torque: Handles wheel lugs, pipe flanges, and concrete anchors with ease.
Precision Wrench Control: Prevents overtightening and fastener run-off for safer work.
3 Speed Modes: Match torque to the application—light, medium, or heavy.
Brushless Motor: Increases efficiency and runtime vs. brushed models.

Choosing the right mode can prevent damage. Start in Mode 1 for plastic fasteners or small bolts, switch to Mode 2 for aluminum wheels, and use Mode 3 for stubborn rusted steel. The tool's LED light also helps illuminate dark areas.
Pair with a DEWALT 5Ah XR battery for longest runtime. The brushless motor draws only the power needed, so you can get more work done per charge.
If you need more than 330 ft-lbs, consider the DCF899 (around 700 ft-lbs), but for 95% of automotive and equipment tasks, the DCF894B offers a great balance of power, weight, and control.
No, this is the bare tool only. It requires a DEWALT 20V MAX battery and charger.
Mode 1 delivers up to about 100 ft-lbs for light work, Mode 2 up to 250 ft-lbs for general fastening, and Mode 3 provides the full 330 ft-lbs maximum.
Yes, the DCF894B is commonly used for automotive lug nuts and suspension work.
The detent pin anvil holds sockets securely; use a standard 1/2-inch impact socket.












This impact wrench loosens lug nuts that my old one couldn't budge. The three speeds let me ease into delicate work. The compact size fits in tight wheel wells. It's the best tool in my box.
Works on my car. No battery included, so you need one.
I tested this on a torque wrench and it hits the spec. The housing is solid. No complaints. It's become my go-to.
I bought this as a bare tool because I already have DEWALT batteries. It's strong, compact, and the speed control is useful. The reverse switch is easy to use. Great for suspension work.
It's a beast.
I've been turning wrenches for 45 years. This is the easiest impact I've ever used. The power is excellent and it's light. My old air tools are staying in the cabinet.
Struggled with rusted bolts. Maybe I need a bigger one.
Took off rusty lug nuts without breaking a sweat. The battery lasts long. I like the belt clip. Great purchase.
He uses it in his shop constantly and says it's the best. The control helps not to strip bolts.
Works fine.
I'm a weekend mechanic and this has made working on my truck easier. It's compact enough to fit between the frame and body. The Precision Wrench Control kept me from over-tightening bolts on the brake calipers. I highly recommend this to anyone.
No issues.
