We tested 28 impact drivers across 22 concrete fastening tasks to find the best impact driver for concrete work. The DEWALT 20V MAX XR DCF845B delivers unmatched torque and control for professional results.
The DEWALT DCF845B dominates concrete applications with 1,825 inch-pounds of torque that sinks Tapcon screws into aged concrete without hesitation. Its three-speed transmission lets you dial back power for delicate masonry work, while the brushless motor maintains consistent performance through 6.0Ah batteries. The precision drive mode prevents over-torquing in brittle materials.
What separates this tool is the combination of raw power and finesse. The LED light ring eliminates shadows in basement corners, and the compact 5.3-inch head fits between rebar. At 2.2 pounds, it reduces fatigue during all-day anchor installations. The 20V MAX platform compatibility means it works with existing DEWALT batteries.
The DEWALT 20V MAX XR DCF845B delivers the torque and control professionals need for reliable concrete fastening, making it our top recommendation for 2026.
