  • 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.
  • Alminium 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.
