Key Features & Benefits
- 450 RPM high speed — more than double the 200 RPM of the standard extended reach ratchet, drastically reducing run-down time on long-thread fasteners and repetitive bolt sequences.
- Extended reach neck — gets past engine covers, intake manifolds, and body panels without extension bars that introduce wobble and reduce torque transfer.
- 47.5Nm torque — enough to break free most automotive service fasteners while remaining controllable for trim and electrical panel screws.
- 19mm low-profile head — fits into clearances under 20mm between components, hoses, and wiring looms where conventional ratchet heads would not pass.
- Recessed F/R shift knob — sits below the profile of the tool body so it cannot be bumped into reverse accidentally when working in tight spaces.
- FUEL brushless motor — delivers consistent speed and torque throughout the battery charge cycle without the gradual slowdown of brushed motors.
Speed Where It Counts
The high-speed variant is built for technicians who run down dozens or hundreds of fasteners per shift — production line assembly, fleet servicing, or heavy equipment maintenance. The 450 RPM free speed cuts run-down time in half compared to the standard 200 RPM extended reach ratchet, while the extended neck still reaches the fasteners that compact ratchets cannot.
