Key Features & Benefits
- 75 Nm maximum torque — enough power to run down and snug 3/8-inch fasteners in automotive, mechanical and assembly applications efficiently.
- FUEL brushless motor — delivers up to two times longer motor life than brushed alternatives, with consistent torque throughout the battery cycle.
- 3/8-inch square drive — the most common socket size for general automotive and mechanical work, accepting standard 3/8″ impact sockets directly.
- Low-profile head design — the slim ratchet head slides between bolts and surrounding components in tight spaces where bulkier tools cannot reach.
- 200 RPM no-load speed — faster than the 1/2″ model for quicker fastener run-down on lighter applications.
- Variable-speed metal trigger — feather for slow, controlled tightening on delicate fasteners or pull through for full-speed operation.
- Built-in LED and fuel gauge — illuminates the work area directly and shows remaining battery life at a glance.
- Reinforced steel yoke housing — cast steel mechanism housing withstands the repeated impact forces of daily professional use.
When to Use This Ratchet
The M12FIR38-0 is the standard-duty cordless ratchet for automotive mechanics, HVAC technicians and plant maintenance workers. The 3/8-inch drive handles the majority of fasteners in engines, brake assemblies and general mechanical work. Choose the 3/8″ over the M12FIR12-0 (1/2″) when working with smaller fasteners where the 1/2″ drive is overkill, or when you need the slightly faster 200 RPM speed.
