Fasten with Speed in the Tightest Spaces: 70 ft-lbs of Torque in a Compact, Oil-Resistant Frame.

Stop struggling with manual ratchets in cramped engine bays. The DEWALT DCF512B 20V MAX ATOMIC™ Brushless 1/2-Inch Ratchet* is the ultimate solution for mechanics and technicians who need to balance power with maneuverability. Delivering up to 70 ft-lbs of max torque, this cordless ratchet allows you to install and remove fasteners quickly, while the ATOMIC™ Compact Series design ensures you can reach those "impossible" bolts that standard tools can't touch.

Note: This is a Bare Tool (Battery and Charger sold separately).

Why the DEWALT DCF512B ATOMIC™ is the Professional’s Choice:

• 70 ft-lb Max Torque: Get the job done faster. This ratchet provides the torque needed for a wide range of automotive and maintenance applications, significantly reducing hand fatigue and project time.
• Oil-Resistant Glass-Filled Nylon Housing: Built for the shop environment. The tool’s housing is designed to resist damage from common automotive chemicals, solvents, and oils, ensuring it stays in the rotation for years.
• Brushless Motor Efficiency: The high-performance brushless motor delivers more power and longer motor life compared to traditional brushed motors, maximizing your 20V MAX* battery runtime.
• Variable Speed Trigger: Maintain total control. The trigger allows you to modulate the speed based on the task, preventing over-tightening of delicate fasteners or providing full speed for rapid removal.
• Integrated LED Work Light: Never work in the dark again. The built-in LED illuminates your workspace, making it easier to line up sockets on hidden fasteners in dark undercarriages or engine compartments.
• Trigger Lockout: Peace of mind in your toolbox. The integrated lockout switch prevents accidental activation while the tool is stored in your bag or chest.
