• 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.

  

• 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.)

  

Thanks to Our original, compact & high efficiency inverter circuit.

• by the internal double-insulation construction with an aluminium die-cast body which firmly holds the rotor shaft, and a plastic stator holder.

  

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

  

Reduces slippage and fits comfortably in the hand.

Allows quick switching between forward and reverse modes.
