A fact-checked comparison of five current cordless impact drivers, with real torque specs, bare-tool vs. kit warnings, and battery-platform lock-in explained.
Based on published specs and independent bench testing, the DeWalt DCF860B has the strongest claim to "most powerful" here: its 2,500 in-lbs rating is the highest of the five, and Pro Tool Reviews' own fastener-driving tests had it out-driving Milwaukee's 2953-20 in the same session. That said, "most powerful" isn't the same as "best for you," the Makita XDT16Z trades peak torque for genuinely useful speed and cam-out control, the Bosch Freak's 1/2-inch square drive lets it swing sockets a plain impact driver can't, and the Ryobi PBLID02B is the only one here built around a genuinely inexpensive, DIY-friendly battery ecosystem. Every one of these five ships as a bare tool on the ASIN we verified, so factor a battery and charger into your budget regardless of which one you pick.

Buyer checklist
We pulled specs directly from each manufacturer's own product pages, cross-checked them against the exact Amazon listings we verified (not third-party resellers with rewritten titles), and layered in independent test data from outlets like Pro Tool Reviews and user-reported issues from tool forums where we found them. This is a research and documentation exercise, not a hands-on lab test, these tools were not physically run, and the handful of places where manufacturer marketing and independent testing don't fully agree are flagged directly.
No. A drill/driver spins continuously and is built for drilling holes and light driving; a hammer drill adds a forward-and-back hammering action for masonry. An impact driver instead delivers rotational hammer blows (measured in impacts per minute) only when it meets resistance, which lets it drive long screws and lag bolts without the bit camming out or the user's wrist absorbing the torque. Impact drivers use a 1/4-inch hex chuck for quick-change bits rather than a drill's three-jaw chuck, though the Bosch Freak in this comparison adds a 1/2-inch square drive as well.
Not necessarily. The DeWalt DCF860B's 2,500 in-lbs is the highest spec in this group, but the Makita XDT16Z's 1,600 in-lbs figure doesn't mean it's a weaker tool for most jobs, Makita puts more of its engineering into speed control (four speeds, Quick-Shift Mode, an anti-cam-out Assist Mode) than into chasing a peak torque number. For everyday deck screws and framing, mid-range torque with good speed control is often more useful day to day than maximum torque, which mostly matters for large lag bolts, structural screws, and breaking loose rusted fasteners.
No, M18 (Milwaukee), 20V MAX (DeWalt), 18V LXT (Makita), Bosch's 18V system, and 18V ONE+ (Ryobi) are all proprietary and physically incompatible with one another, regardless of the fact that most of them are nominally similar voltage. This is a real, deliberate lock-in: once you buy into one brand's battery platform, every future bare-tool purchase only makes sense within that same ecosystem, which is why picking a brand is as much a long-term platform decision as a single-tool purchase.
