DEWALT 20V MAX XR Impact Driver DCF845B 1/4-inch High-Torque Brushless, 3-Speed Tool Only with LED

Built for tradespeople and serious DIYers, this cordless impact driver pairs a high-efficiency brushless motor with a slim, ergonomic body to drive large-diameter screws and fasteners in tight spaces. As a TOOL CONNECT chip-ready tool (chip sold separately), it integrates with DEWALT's system for jobsite management while the integrated 3-LED work light improves visibility when working in dim corners.

How does the three-speed system improve control on different jobs?

The DCF845B offers three distinct speed ranges that let you match power and precision to the task — low for delicate starts, mid for general fastening, and high for brute-force driving. The variable speed trigger adds another layer of modulation so you can fine-tune torque on-the-fly.

• Speed 1: low RPM for precise screw placement and avoiding overdriving
• Speed 2: mid RPM for everyday fastening tasks
• Speed 3: high RPM (up to 3,400 RPM) for driving larger screws quickly
• Variable speed trigger for incremental control throughout the pull

What kind of power and runtime can I expect from the brushless motor?

The brushless motor is engineered for efficiency and extended runtime while producing up to 1,825 in-lbs of max torque to handle demanding fastening applications. Brushless design reduces friction and heat, so the tool runs longer between battery charges and requires less maintenance than brushed models.

• Maximum torque: 1,825 in-lbs for heavy fasteners
• Top speed: up to 3,400 RPM for rapid driving
• Improved efficiency: brushless motor reduces energy loss for extended runtime
• Battery & charger sold separately — compatible with DEWALT 20V MAX system

What jobsite features make this impact driver practical for daily work?

DEWALT designed the DCF845B with jobsite realities in mind: a compact form factor for tight access, an integrated three-LED worklight for low-light conditions, and a belt hook for quick carry. It’s also Chip Ready for integration into TOOL CONNECT, enabling inventory and tool tracking when you add the optional chip.

• Compact, ergonomic body for access in confined spaces
• 3-LED work light brightens dark work areas for safer, more accurate driving
• Belt hook provides hands-free carry and quick access between tasks
• Chip Ready for TOOL CONNECT compatibility (chip sold separately)

How durable and supported is this model for professional use?

The DCF845B is built with construction environments in mind and comes backed by DEWALT’s three-year limited warranty. Materials and assembly meet trade expectations for a robust cordless impact driver able to withstand daily handling on busy jobsites.

• Rugged construction suited to jobsite wear and tear
• 3-year limited warranty from DEWALT for added peace of mind
• Compatible with the broader DEWALT 20V MAX platform for shared batteries and accessories

Who is this for? The DEWALT 20V MAX XR DCF845B is aimed at professionals and advanced hobbyists who need a compact but powerful impact driver that balances torque, speed control, and on-site durability. Choose this tool if you drive large-diameter screws frequently, work in constrained spaces, or want a CHIP READY unit that can be added to DEWALT’s TOOL CONNECT system.
