DeWalt 20V MAX Brushless Cordless 3-Speed 1/4 in. Impact Driver

DeWalt 20V Brushless Cordless Impact Driver: A Detailed Review

I've had the pleasure of using various impact drivers over the years, and when I got my hands on the DeWalt 20V MAX Brushless Cordless 3-Speed 1/4 in. Impact Driver (DCF850P2), I was eager to see how it performed. DeWalt has a reputation for producing reliable and durable power tools, and this compact impact driver promised to deliver both power and versatility in a small package.

Design and Build Quality

One of the first things that struck me about this impact driver is its compact size. Measuring under 4 inches, it is designed to access tight spaces with ease, making it an excellent choice for tasks in confined areas. The tool feels solid in hand, with DeWalt’s signature yellow and black color scheme giving it a professional appearance.

The brushless motor is a standout feature, designed to provide both high torque and long battery life. With 1,825 in-lb of torque and a maximum speed of 3,250 rpm, this little guy packs a punch. The build quality is robust, and it can withstand the rigors of daily use on a job site. I've dropped it from various heights, and it has held up remarkably well, which speaks volumes about its durability.

Performance

In terms of performance, the DeWalt impact driver lives up to its promise. The variable 3-speed trigger allows for enhanced control, making it suitable for a wide range of applications. Whether I was driving large screws into dense wood or working on more delicate tasks, the tool performed consistently.

The 1,825 in-lb of torque is more than sufficient for most tasks, and it handled driving 3/8 x 10” structural screws into wet pressure-treated lumber without any issues. The battery life is impressive as well; I used it with the 5.0 Ah lithium-ion batteries, and it lasted for hours on a single charge. The integrated 3-LED work light is a thoughtful addition, providing excellent visibility in low-light conditions.

Usability

The compact design is a game-changer, especially when working in tight spaces. I found it particularly useful for face screwing inside joist bays and other confined areas where a standard-sized driver wouldn't fit. The tool is well-balanced, and even with the larger 5.0 Ah battery, it didn't feel cumbersome.

However, one issue I encountered was heat buildup. During extended use, the tool can get quite hot, particularly around the metal bits. This is something to be mindful of, as it can lead to discomfort or even minor injuries if you're not careful. Wearing gloves can mitigate this issue, but it’s something DeWalt might want to address in future iterations.

Quick-Change Chuck

The quick-change chuck is designed to make bit changes fast and easy, and for the most part, it works as intended. However, I did experience some minor issues with the collar. On a few occasions, the spring mechanism that holds the bits in place seemed to falter. This required some maintenance to fix, but it wasn’t a deal-breaker for me. It's a minor inconvenience that can be easily addressed, but it’s worth noting.

Comparison to Other Models

Having used other DeWalt models like the DCF885 and DC809, I found the DCF850P2 to be on par, if not superior, in several aspects. The compact size gives it an edge in tight spaces, and the brushless motor offers a slight performance boost. However, if size isn't a critical factor for you, the DC809 is also an excellent choice and might perform slightly better in terms of raw power.

Battery and Charger

The impact driver comes with two 5.0 Ah lithium-ion batteries, which provide long-lasting power. The batteries charge relatively quickly, and having a backup ensures that you can work uninterrupted. I appreciated the balance between battery life and tool weight, as the larger capacity batteries didn't make the tool unwieldy.

Conclusion

Overall, the DeWalt 20V MAX Brushless Cordless Impact Driver (DCF850P2) is a versatile and powerful tool that excels in a variety of applications. Its compact size allows for increased maneuverability in tight spaces, and the brushless motor delivers impressive torque and speed. The three-speed settings provide excellent control, and the integrated LED lights are a useful feature for low-light conditions.

However, the tool’s tendency to heat up during extended use is a notable drawback. Additionally, the quick-change chuck, while convenient, could use some refinement to improve reliability.

Would I recommend this impact driver? Absolutely. Despite its minor flaws, the DCF850P2 offers a great balance of power, size, and versatility. It’s a reliable choice for both professionals and DIY enthusiasts. If you’re in the market for a compact yet powerful impact driver, this DeWalt model should be at the top of your list.
