Cons
- Requires a DEWALT 20V MAX battery and charger — this is a bare tool only.

The DCF845B delivers 1,825 in-lbs of torque and three distinct speed settings, giving precise control across a wide fastening range — from setting cabinet screws without damage to driving 6-inch lag bolts. Its brushless motor spins up to 3,400 RPM, cutting driving time on large projects.
Build quality is solid, with a comfortable 2.2-lb body that balances well overhead. The electronic speed switch provides a distinct, tactile feel, and the impact mechanism seats fasteners progressively, reducing the tendency to overdrive. In daily use, the tool's power is immediate and predictable, making long assembly sessions less tiring.
A bare-tool purchase, it requires an existing DEWALT 20V MAX battery and charger. For professionals and serious DIYers already invested in the DEWALT platform, it delivers high-end torque and speed control without paying for bundled batteries. Buyers who push tools to their limits daily should be aware that sporadic early durability issues can occur — a tradeoff for its mid-range price. Casual users may find this level of power unnecessary, but for those who need fast, precise fastening in demanding applications, the DCF845B is a purpose-built choice.
💡 💡 Tip: During extended heavy-duty driving, let the driver cool between battery swaps to reduce thermal stress and extend motor life.
Bottom line: For DEWALT 20V MAX users seeking maximum torque and speed precision in a bare tool, the DCF845B is a standout — but pros pushing it all day should factor in the occasional need for a backup.
