**1. Power and Performance
The Dewalt DCF840: This model boasts a robust brushless motor that delivers up to 2,800 RPM and 3,200 IPM (Impacts Per Minute). It’s designed for tackling a wide range of fastening applications, from driving screws into wood to fastening bolts into metal. With its 20V Max XR battery, it offers impressive power and runtime.
The Dewalt DCF850: On the other hand, the DCF850 takes things up a notch. It features Dewalt’s Power Detect technology, which automatically adjusts power output based on the type of fastener you’re using. This means you get a whopping 2,900 RPM and a jaw-dropping 4,100 IPM when paired with a 20V Max XR battery. The DCF850 is engineered for heavy-duty tasks, making it a go-to choice for professionals tackling demanding projects.
Example: Imagine you’re building a deck, and you need to drive long screws through pressure-treated lumber. The DCF850’s higher IPM will make quick work of this task, reducing fatigue and saving you time compared to the DCF840.
**2. Size and Ergonomics
The Dewalt DCF840: This model features a compact design, measuring just 5.3 inches front to back. It’s lightweight and well-balanced, making it comfortable to use for extended periods. The grip is textured for added control and reduced slippage.
The Dewalt DCF850: While the DCF850 is slightly larger at 5.8 inches front to back, it maintains a well-balanced feel. Dewalt has also incorporated a textured grip for enhanced control and comfort during prolonged use.
Example: If you often work in tight spaces where maneuverability is crucial, the DCF840’s compact size may be preferable. However, if you prioritize power and can handle a slightly larger tool, the DCF850 won’t disappoint.
**3. LED Lighting
The Dewalt DCF840: This model comes equipped with three LED lights around the chuck. The lights stay on for 20 seconds after trigger release, illuminating your work area and improving visibility in dimly lit conditions.
The Dewalt DCF850: The DCF850 takes it up a notch with a 3-mode LED lighting system. You can choose between “Spot,” which provides focused illumination, “Flood,” for broader coverage, or “Duo,” which combines both modes. This advanced lighting system ensures you can always see what you’re working on, no matter the conditions.
Example: Imagine you’re installing a cabinet in a poorly lit corner of a room. The DCF850’s versatile LED lighting options will undoubtedly be a game-changer, allowing you to adjust the lighting to your specific needs.
**4. **Price Point
The Dewalt DCF840: As the older model, the DCF840 tends to be more budget-friendly. You can often find it at a lower price point than the DCF850, making it an attractive option for those looking for a reliable impact driver without breaking the bank.
The Dewalt DCF850: Due to its advanced features and performance capabilities, the DCF850 typically comes with a higher price tag. However, for professionals who demand top-tier performance, the investment may be well worth it.
Example: If you’re a DIY enthusiast looking for an impact driver for occasional projects, the DCF840 might be the better choice due to its affordability. However, if you rely on your impact driver for daily work, the DCF850’s power and durability could pay off in the long run.
5. Battery Compatibility
The Dewalt DCF840: This model is compatible with all Dewalt 20V Max batteries, including the XR line. If you already own Dewalt tools that use these batteries, you’ll appreciate the compatibility and interchangeability.
The Dewalt DCF850: Similarly, the DCF850 is compatible with 20V Max batteries, but it shines when paired with the XR line, especially the 8.0Ah and 6.0Ah versions. The Power Detect technology mentioned earlier optimizes performance when used with these batteries.
Example: If you’re already invested in Dewalt’s 20V Max XR battery ecosystem, both models will work seamlessly. However, if you’re looking for the most optimized performance, consider using the DCF850 with the high-capacity XR batteries.
6. Warranty and Durability
The Dewalt DCF840: Dewalt tools are known for their durability, and the DCF840 is no exception. It typically comes with Dewalt’s standard 3-year limited warranty, giving you peace of mind in case of any issues.
The Dewalt DCF850: With its robust construction and advanced features, the DCF850 also benefits from Dewalt’s 3-year limited warranty. However, due to its Power Detect technology and increased power output, it might be subject to more wear and tear over time.
Example: If you’re particularly hard on your tools or anticipate heavy daily use, consider investing in a comprehensive extended warranty for added protection, especially for the DCF850.
7. Noise Level
The Dewalt DCF840: This model is relatively quiet, emitting around 96 decibels (dB) during use. While it’s not entirely silent, it won’t deafen you during extended use.
The Dewalt DCF850: With its increased power and performance, the DCF850 generates more noise. It can produce up to 105 dB, which is noticeably louder. Ear protection is advisable, especially if you’ll be using it for prolonged periods.
Example: If you’re working in noise-sensitive environments or simply value a quieter workplace, the DCF840 may be the more considerate choice.
8. Upcoming Models and Innovations
The Dewalt DCF840: As an older model, the DCF840 may not benefit from the latest innovations and technological advancements that Dewalt may introduce in newer models.
The Dewalt DCF850: Being a newer and more advanced model, the DCF850 is likely to benefit from ongoing improvements and innovations, ensuring it stays competitive in the market.
Example: If you’re future-proofing your tool collection and want access to the latest features and technologies, the DCF850 may be a more future-ready choice.
