Key Features & Benefits
- 47 Nm maximum torque — enough power for general-duty fastening and run-down work on 3/8-inch socket applications in automotive and mechanical environments.
- 250 RPM no-load speed — the fastest in the M12 ratchet range for quick fastener run-down on lighter applications.
- 19 mm low-profile head — one of the slimmest ratchet heads available, fitting between bolts and bodywork in tight engine bays and suspension assemblies.
- 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 housing — durable construction withstands the repeated impact forces of daily professional use.
- REDLINK overload protection — electronic protection in tool and battery prevents overloading and overheating.
- M12 battery compatibility — shares batteries with the full M12 cordless range for a single-platform workshop.
When to Use This Ratchet
The M12IR-0 is the entry-level cordless ratchet for mechanics and technicians who want to replace pneumatic ratchets without the premium price of the FUEL models. The 47 Nm torque handles general-duty fastening, and the 250 RPM speed is the fastest in the M12 range. Choose this when you need an affordable cordless ratchet for lighter applications and do not require the 75–81 Nm torque of the FUEL models.
