"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

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
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.

Aluminium Housing Body
Durability 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

Bumper : Protects the hammer case.
Tail Bumper : Protects the housing.

Soft grip

Reduces slippage and fits comfortably in the hand.

New trigger
Tumbler-type forward/reverse switch

Allows quick switching between forward and reverse modes.

Hanger

Designed to be hung on a rope and a wire. (For WR25SE)
