Cordless 3/8" Ratchet DeWalt DCF503N 12V, 81 Nm, body only (no battery or charger)

DeWalt DCF503N is a 12V cordless 3/8" ratchet designed to deliver up to 81 Nm of torque for fastening and loosening bolts and nuts in confined or hard-to-reach spaces. Supplied as a tool-only unit, this compact ratchet features a 3/8" square drive compatible with standard sockets and a brushless motor for improved efficiency and longer tool life. The ergonomic form factor and balanced weight make it suitable for trade, maintenance, and automotive applications where space and precision matter.

Advantages

The brushless motor provides efficient power delivery and reduced maintenance compared with brushed alternatives, while the compact 3/8" square drive enables access in tight spaces. Lightweight and ergonomically shaped, the tool reduces operator fatigue during repetitive tasks. As a tool-only offering, it allows users who already own compatible 12V batteries and chargers to expand their kit without redundant accessories.

Suitable for

• Automotive repair and under-hood work where clearance is limited
• HVAC and electrical maintenance in confined installations
• General trade and assembly tasks requiring controlled torque in tight spaces
• Plumbing and mechanical servicing with socket-based fasteners

Key specifications

• Drive size: 3/8" square drive for standard sockets
• Voltage: 12 V (tool-only, battery and charger not included)
• Maximum torque: up to 81 Nm
• Motor type: brushless for higher efficiency and durability
• Intended use: fastening and loosening bolts and nuts in confined spaces
• Form factor: compact and lightweight for improved access and ergonomics

How to use

Fit a compatible 3/8" socket onto the square drive and select the appropriate speed or mode if the tool has settings. Secure a charged 12V battery from the same compatible range (battery and charger sold separately) onto the tool according to DeWalt instructions. Position the socket on the fastener, apply steady pressure to maintain engagement, and operate the trigger to tighten or loosen as required. Observe torque limits and finish manually when precise final torque is needed.

Usage recommendations

For safe and reliable operation, use DeWalt-compatible 12V batteries and a charger, wear appropriate personal protective equipment, and regularly inspect sockets and attachments for wear. When working on torque-critical applications, verify final torque with a calibrated torque wrench. Store the tool in a dry place and follow manufacturer service intervals for optimal performance.
