The DEWALT 20V MAX XR Impact Driver (DCF845B) is a high-performance cordless tool designed for professionals and serious DIYers. It packs 1825 in-lbs of torque and 3400 RPM, making it ideal for driving large diameter screws and tackling tough fastening jobs. This tool is a worthy upgrade for anyone needing reliable power in a compact package.
Standout features include a brushless motor that delivers 30% more torque than previous models, alongside three speed settings and a variable speed trigger for precise control.

The DEWALT 20V MAX Cordless Drill and Impact Driver Combo Kit is a well-rounded solution for homeowners, DIYers, and contractors who need reliable cordless tools without breaking the bank. This kit combines a compact drill/driver with a powerful 1/4-inch impact driver, making it suitable for general drilling, fastening, and driving tasks around the home or on job sites.
What sets this combo apart is its thoughtful engineering for real-world use. Both tools feature integrated LED work lights with a convenient 20-second delay, ensuring you can see what you are doing in dim spaces without constantly running down the battery. The compact dimensions, measuring just 7.5 inches for the drill and 5.55 inches for the impact driver, make these tools genuinely useful in tight spaces where full-size tools simply won't fit. The one-handed bit loading system on the impact driver keeps your other hand free and speeds up repetitive fastening work.
Build quality reflects DEWALT's reputation for durability. The drill features a 1/2-inch single sleeve ratcheting chuck that grips bits securely, while the impact driver's 1/4-inch hex chuck accepts standard 1-inch bit tips. Both tools feel well-balanced and the lightweight construction minimizes fatigue during extended use. The included durable storage bag keeps everything organized and portable, a practical touch that justifies the kit format.
The main limitation is that these are entry-level to mid-range tools within the DEWALT lineup. While perfectly adequate for general home improvement and light professional work, users tackling heavy-duty construction may eventually want more power. Additionally, the included batteries are compact and may need frequent recharging during intensive use, though the charger is included in the kit.
Overall, this DEWALT combo kit delivers excellent value and real-world usability. With strong customer ratings and a 3-year limited warranty backing your purchase, it is a smart choice for anyone building a cordless tool collection or upgrading from older models.
This kit is ideal for homeowners tackling DIY projects, weekend warriors, and professional contractors who appreciate versatile, compact tools. If you frequently work in confined spaces like attics, crawl spaces, or under cabinets, the compact design is a major advantage. The combo format makes sense if you are starting fresh with cordless tools or expanding an existing collection.
You should also consider this kit if you value convenience and want everything included out of the box. With two batteries and a charger provided, there is no need to purchase additional accessories separately. The included storage bag adds practical value for job site portability.

Buying Guide
Torque and Power
Torque is the primary measure of an impact driver’s capability. Higher torque means the tool can drive larger screws and bolts without stalling. For DIY tasks like building furniture or hanging cabinets, a torque range of 1,500 to 2,000 in-lbs is ideal. The DEWALT 20V MAX XR Impact Driver delivers 1,825 in-lbs, while the combo kit offers sufficient power for most home projects. Consider your typical fastening needs when evaluating torque ratings.
Speed and Control
Variable speed triggers and multiple speed settings allow you to adjust the tool for different materials. A three-speed option gives you precision for delicate work and full power for heavy-duty tasks. The DEWALT 20V MAX XR Impact Driver features three speeds, providing pro-level control. For detailed work on smaller projects, a slower speed prevents overdriving screws. If you often switch between tasks, a multi-speed driver offers versatility.

Ergonomics and Size
DIY projects often involve tight spaces, such as inside cabinets or between studs. A compact and lightweight impact driver reduces fatigue and improves accessibility. The DEWALT combo kit includes tools with short lengths and low weight, making them easy to maneuver. Look for a tool that feels balanced in your hand, with a comfortable grip. A belt hook is also a valuable addition for keeping the tool within reach. For budget-friendly options, explore our best cordless drills under $150 list.
Battery System and Runtime
Since impact drivers are cordless, battery compatibility and runtime are crucial. DEWALT’s 20V MAX system is widely used, meaning you can share batteries with other tools. The combo kit includes two batteries and a charger, ideal for extended projects without downtime. The XR model is tool-only, so you need an existing battery system. For home use, having at least two batteries ensures continuous work. For more on battery-powered tools, check our best cordless drills under $100 guide.
Final Thoughts
Choosing the right impact driver for your DIY projects comes down to your specific needs. If you want a complete setup with a drill and impact driver, the DEWALT 20V MAX Cordless Drill and Impact Driver combo kit offers excellent value and versatility for a wide range of tasks. For those who already have batteries or need maximum torque for heavy-duty fastening, the DEWALT 20V MAX XR Impact Driver provides pro-level power and precision in a compact package.
