New AC brushless motor technology
Better performance at voltage drops
Traditional brushed motors
Continually monitors power and load, and provides stable torque even with extension cord use
In carbon brushed motors, carbon brushes contact the motor to complete the circuit and power the tool. Brushes wear and occasionally need maintenance for replacement. The mechanical contact of the brushes on the motor causes electrical loss and frictional resistance, as well as heat build-up and contact wear – all of which robs the motor of performance and decrease durability.

Brushless motors
Brushed motor model
In brushless motors a micro-processor controls the current flow through the motor. This means there are no carbon brushes which reduces maintenance and unexpected downtime. Due to lack of mechanical contact on the motor, minimal heat and motor wear occur. This results in vastly improved electrical efficiency and power transfer.

Test Condition: Extension cord length 100m (50m cord x 2) with 2.0mm2 nominal cross-sectional area of conductor. (Test condition is just for explanation about and difference in the tools. Please use the appropriate extension cord).
even in locations far from the power source
Can be used with a petrol engine generator
Adjustable impact rate (tightening torque) according to application
Compact body with improved handling
With Hitachi’s tightening mode switch function, the impact wrench can be used for a wide variety of tasks

Tightening torque differs according to the bolt and material size, grade, etc. Confirm the tightening torque by "a" few trials before use in order to ascertain the correct setting and tightening torque to be used.
Light tasks
Heavy tasks
Piping support tools and scaffold installation. Wooden rack, fence, and furniture assembly, etc.
Steel frame assembly, etc.
With overload protection and soft start • Overload protection: Shuts off power to the motor in the event of excessive load conditions • Soft start: Supresses kickback when starting
