DEWALT 20V MAX XR Cordless Ratchet DCF510B | 3/8in & 1/2in Sealed Head, Bare Tool

Powerful, flexible fastening for professional results

The DEWALT 20V MAX XR Cordless Ratchet (DCF510B) brings professional-grade capability to the job site in a compact, maintenance-friendly package. With a brushless motor delivering up to 75 ft-lbs of max torque and a no-load speed of 0–300 RPM, this tool is designed to help you fasten and remove stubborn nuts and bolts with confidence. The interchangeable 3/8in and 1/2in square drive anvils mean you can switch between common sizes without swapping tools, helping you keep momentum on the job.

On the floor of a crowded garage, workshop, or equipment trailer, every turn counts. The ratchet’s lightweight, balanced design reduces fatigue over long days, while the built-in LED light helps you illuminate dark corners, aligning each fastener with precision. The variable speed trigger allows you to tailor your pace to the task at hand, from delicate snugging to firm seating, while the forward/reverse switch keeps you moving efficiently in tight spaces.

Designed to thrive in oil- and solvent-rich environments

The sealed head design, combined with a glass-filled nylon tool housing, helps protect internal components from automotive oils and common solvents you encounter on the job. This durability-forward approach is paired with practical features like a trigger lock to prevent accidental activation when you're setting up or moving between tasks.

Real-world use cases and practical benefits

Imagine a crowded engine bay where space is at a premium and torque is needed without a bulky impact wrench. This ratchet can help you reach fasteners that refuse to budge, while the quick-drive changes reduce downtime between tasks. In equipment maintenance or assembly work, the LED illumination and precise speed control support careful, repeatable results without over-torquing. The bare tool format allows you to pair this tool with your existing DEWALT 20V MAX XR batteries and chargers, letting you tailor power and runtime to your current workflow.

Notes for shoppers: this is a bare tool only. Battery and charger are sold separately, so you can integrate it into your current 20V MAX XR system or build a new kit over time. If your shop already trusts DEWALT for durability and performance, this ratchet adds a versatile option for constrained spaces and fast-paced projects.
