Power Tools
Hitachi WR 22SE
- Smallest & Lightest in its class*1 and “Robust and Highly Durable” design is achieved by the industry-first*2 AC Brushless Motor + Aluminium Housing Body
- Tightening torque: 620Nm
- Maintenance free: The product life cycle is significantly extended by eliminating troubles with armature burnout, layer short or commutator wear in severe environments. No carbon brush replacement is required.
- Stable performance provided even at voltage drops: Power supply and load conditions are continually monitored to provide stable torque even with an extension cord used.
- Tightening torque decrease rate in Test condition: When using 100m extension cord (50m x 2) with 2.0mm2 nominal cross-sectional area of conductor. (This test condition is just for explanation about the difference of the tools. Please use an appropriate extension cord.)
- Compatible with engine generators: Thanks to Hitachi's original, compact & high efficiency inverter circuit.
- Durably remarkably improved: by the internal double-insulation construction with an aluminium die-cast body which firmly holds the rotor shaft, and a plastic stator holder.
- Bumper and Tail Bumper protect the tool body: Bumper protects the hammer case & Tail Bumper protects the housing.
- Soft grip handle: Reduces slippage and fits comfortably in the hand.
- New Trigger
- Tumbler-type forward/reverse switch: Allows quick switching between forward and reverse modes.
