The DeWalt DCF860 delivers a substantial performance leap over its predecessor, offering 2500 in-lbs maximum torque and 3800 RPM top speed. It outperforms competitors like the Flex FX1371A and Milwaukee 2953 in driving tests, completing tasks faster than the DCF845. The tool features a compact design with a 4.8-inch head length and includes LED lighting for dark work environments. While it's more powerful, the increased weight of 2.7 lbs (bare) may be a consideration for some users.

Performance leap over predecessor
The DeWalt DCF860 delivers a substantial performance upgrade compared to its predecessor, the DCF845. This impact driver achieves a maximum torque rating of 2500 in-lbs, which represents a 675 in-lbs increase over the DCF845. The top speed has also improved from 3400 RPM to 3800 RPM, with an impact rate that climbs to 4500 IPM from 4200 IPM. These enhancements translate into practical advantages during real-world use, particularly when driving medium-sized fasteners. Pro Tool Reviews' testing with 8-inch GRK RSS screws showed an average driving time of 7.17 seconds, compared to 8.63 seconds for the DCF845. Similarly, when driving 3/8 x 8-inch lag bolts into stacked OSB subflooring, the DCF860 completed the task in just over 6 seconds, versus 9.06 seconds for the older model.
Speed and torque benchmarks
In head-to-head testing against other flagship impact drivers, the DCF860 shows competitive performance metrics. When compared to the Flex FX1371A, the DCF860 matches the maximum torque at 2500 in-lbs but edges out the competitor in impact rate with 4500 IPM versus 4450 IPM. The Milwaukee 2953 model demonstrates superior performance in practical tests, with faster average times for RSS screws (5.90 seconds vs 7.17 seconds) and lag bolts (5.80 seconds vs 6.12 seconds). However, the DCF860 still maintains a strong position in terms of raw specifications and power output.
Compact design with increased weight
Despite being a flagship model, the DCF860 maintains a relatively compact profile with a head length of 4.8 inches, a reduction from the DCF845's 5.1-inch head. The tool's weight increases to 2.7 pounds in bare form, up from 2.0 pounds for the DCF845, primarily due to the larger motor and internal components required for enhanced performance. When equipped with the kitted 8.0Ah PowerPack battery, the total working weight reaches 4.6 pounds. This additional weight is offset by the tool's excellent balance, making it comfortable to handle during extended use. The design allows for one-handed bit insertion and includes automatic bit ejection, which contributes to its user-friendly operation.
Lighting and ergonomic features
The tool features a tri-LED work light mode, which allows users to select different levels of brightness depending on their needs. The ergonomic design includes a comfortable grip that reduces fatigue during prolonged use. The tool's balance and weight distribution contribute to its ease of handling, making it suitable for both professionals and serious DIY enthusiasts.
Battery performance and compatibility
The DCF860 is compatible with various DeWalt 20V Max batteries, including the 2.0Ah, 5.0Ah, 5.0Ah PowerStack, and 8.0Ah PowerPack. With the kitted 8.0Ah PowerPack battery, the tool achieves a total working weight of 4.6 pounds. The battery provides reliable performance under load, with quick charging capabilities. Users have reported that the battery holds up well during demanding tasks, although the tool's high torque output can strain accessories. One reviewer noted that premium impact bits were snapped during early use, highlighting the importance of using high-quality, impact-rated accessories. The tool's performance remains consistent across different battery capacities, with the larger batteries offering extended runtime for extended projects.
Bit handling and accessory considerations
The DCF860's automatic bit ejection system helps prevent damage to bits and reduces the risk of injury. The one-handed bit insertion feature enhances convenience, particularly when working in tight spaces. However, the tool's high torque output can exceed the strength of certain bits, leading to potential damage. Users have reported that even high-end impact bits can fail under sustained high torque conditions. This suggests that operators should keep spare bits on hand and use only those rated for the tool's maximum torque output. The collet size of 1/4 inch hex provides compatibility with a wide range of accessories, while the tool's design accommodates various bit types and sizes.
Testing under real-world conditions
During practical testing, the DCF860 demonstrated its capability to handle demanding applications beyond standard fastening tasks. Users were able to drive 4-inch deep holes through stacked OSB using a 1-inch spade bit, showcasing the tool's versatility. The testing protocol included driving 8-inch GRK RSS screws and 3/8 x 8-inch lag bolts into stacked OSB subflooring. These tests revealed the tool's ability to maintain consistent performance across different materials and fastener sizes. The tool's performance in these tests exceeded expectations, particularly when compared to previous DeWalt models. The ability to drive fasteners quickly and efficiently makes the DCF860 well-suited for both professional contractors and DIY enthusiasts who require reliable performance.

Counts as 4.60/5 in our score — this publisher's 15 scores on the site average 4.43, so its scores are adjusted down to compare fairly with other publishers.
“The DEWALT 20V MAX XR Impact Driver (DCF860) combines incredible power with a small, lightweight form factor.”
“So, let's give it a go. I'll put it on a fast setting on a setting free. Let's put some lights on. Um, we got HR 18 volt battery 5 amp. This is a 5 by 100 screw. So, let's have a look what I can do. That is quick.”
“If you're looking for a compact quarterinch impact driver that does it all, I think the 850 is a pretty good choice. And if you want something that's a little more premium and that runs a little cooler, by the way, uh and will probably last longer, the 860 is probably the way to go.”
Not in the average — we derived this score from the review's words, and a publisher printed a score for this product, so the printed number counts instead.
Our 4.6 score is the average of 1 of the scored reviews above, each adjusted for how strictly its publisher scores; 2 more reviewed it without printing a score and are not in the average. 1 derived score above is not in the average because a publisher printed a score for this product.
