Power & Performance

The DeWalt DCF891N impact wrench packs serious power into a compact and lightweight package. It delivers an impressive 700 ft-lbs of maximum fastening torque and 1200 ft-lbs of breakaway torque. This high torque output makes it ideal for loosening even the most stubborn lug nuts or bolts.

The DCF891N utilizes a brushless motor that delivers efficient power while generating less heat. It has a variable speed trigger that allows you to dial in just the right amount of power, with 0-400 RPM and 0-1900 IPM of impact speed. The 1/2" hog ring anvil provides versatility for use with different socket sizes and types.

The impact mechanism utilizes a heavy-duty twin hammer system. This generates the high torque output in short bursts while also reducing vibration. The twin hammers engage one after another in a ripple effect rather than simultaneously. This results in a more controlled impact energy delivery compared to single hammer mechanisms.

Overall, the DCF891N combines DeWalt's latest brushless motor technology with an efficient and durable impact mechanism to deliver outstanding power and speed in a compact format suitable for automotive and heavy duty fastening applications. The variable speed trigger gives users precise control over the power delivery.

To maximize the versatility of the DCF891N impact wrench, consider adding the DeWalt DT7508-QZ 1/4 Hex to 1/2" Square Impact Wrench Adapter. This simple adapter allows you to use 1/4" hex bits and sockets with the DCF891N's 1/2" anvil. It can save you time and money since you won't have to purchase duplicate sockets and bits in both 1/4" and 1/2" sizes.

The DT7508-QZ is made from chrome vanadium steel for durability and corrosion resistance. It has a detent pin that helps retain sockets and bits securely during use. The adapter's compact 2.4" length keeps the overall tool setup as streamlined as possible.

By adding the DT7508-QZ to your toolbox, you can maximize the capabilities of your DCF891N impact wrench. You'll gain the flexibility to tackle a wider range of fastening and repair jobs without being limited to just 1/2" drive sockets. This inexpensive adapter pays for itself quickly by expanding the usefulness of your power tools.

Battery & Charger

The DeWalt DCF891N comes with a powerful 18V XR Lithium-Ion battery that delivers outstanding runtime and performance. The 18V battery platform is highly versatile and compatible with DeWalt's extensive line of 18V tools and accessories.

The battery has a large 5.0Ah capacity, providing longer runtime between charges. With its high power output, the battery can sustain the high torque demands of the impact wrench during prolonged use.

It uses DeWalt's XR Li-Ion cells which deliver up to 33% more capacity over standard packs. The cells have optimized chemistry for maximum runtime and durability.

For fast, convenient charging, the impact wrench includes DeWalt's DCB115 quick charger. It can fully charge an 18V XR battery in about 60 minutes. The charger plugs into AC outlets and has an LED display showing charge status.

The charger and battery pack combine to deliver productivity enhancing performance. You'll spend less time waiting for batteries to charge and more time working.

Cons

While the DeWalt DCF891N impact wrench has many great features, there are some downsides to consider:

• Price - This is a premium tool that comes at a premium price. The bare tool alone costs over £200, so it's a significant investment. When you factor in the need to purchase batteries and a charger separately, the total cost rises even more. For some buyers, it may be out of their budget.

• Noise Level - Impact wrenches are notoriously loud tools. The DCF891N produces a noise level of around 86 dB according to DeWalt. This level of noise can be fatiguing and potentially damaging over long periods of exposure without hearing protection. Ear defenders are a must when using this tool.

• Battery Not Included - An annoying omission is that the DCF891N doesn't include a battery or charger. You'll need to purchase these separately if you don't already have compatible DeWalt 18V XR batteries. This adds to the overall cost and inconvenience for the user.

So while the DCF891N delivers excellent power and performance, the high price tag, noisy operation, and lack of included battery may be drawbacks for some users. Considering your needs and budget, these cons should be weighed against the many pros of this impact wrench.

Ideal Uses

The DeWalt DCF891N impact wrench is ideal for automotive, construction, and home project applications where high torque and power is needed.

For automotive uses, its compact size allows access into tight engine bays when removing lug nuts or bolts on suspension components.

Alternatives

When looking for an impact wrench, the DeWalt DCF891N is a great option but there are a few other models worth considering as well:

Milwaukee 2767-20 M18 Fuel

The Milwaukee 2767-20 is another top pick in the 18V impact wrench category. It has a max torque of 700 ft-lbs which is comparable to the DeWalt's 700 ft-lbs. The Milwaukee is a brushed motor while the DeWalt uses a brushless motor. Brushless motors tend to be more efficient, run cooler, and have a longer lifespan. The Milwaukee does have a detent pin anvil which allows for quick socket changes. Overall, the Milwaukee 2767-20 gives the DeWalt strong competition.

Ingersoll Rand W7150-K2

For those needing even more power, the Ingersoll Rand W7150-K2 steps it up to a max torque of 1100 ft-lbs. This comes from its 2 battery design. It's heavier than the other models at over 15 lbs. The Ingersoll is ideal for heavy duty bolting needs but may be overkill for general automotive work. It's built to withstand abusive industrial environments.

Makita XWT11Z 18V LXT

On a lower budget, the Makita XWT11Z can save over £100 compared to the DeWalt while still providing decent power. It has a max torque of 470 ft-lbs which should be sufficient for most automotive uses. It uses a 4-pole motor which improves efficiency. The anvil is a 1/2" square drive for quick bit changes. Overall the Makita XWT11Z is a good budget-friendly alternative.

Conclusion & Recommendation

Overall, the DeWalt DCF891N XR Brushless 1/2" Impact Wrench is an excellent choice for automotive and construction professionals who need serious power and performance. It delivers up to 700 ft-lbs of max torque and 1200 ft-lbs of max breakaway torque, easily handling lug nuts and other stubborn fasteners. The brushless motor provides more runtime and durability compared to brushed motors.

The 3-speed selector allows you to choose the right power and speed for each application. It has an ergonomic grip and weighs only 7.2lbs for reduced fatigue. The LED light is helpful when working in dim areas. An integrated belt hook adds convenience.
