Various functions, low noise and accurate operation. The next-generation power tool gains unprecedented performance thanks to the advanced electronic control and brushless motor.

Electronic Pulse System
Provides low noise operation

Adoption of the electronic pulse system, which is the first in the power tool
industry, has realized the top-level of low noise.
This allows users to operate the tool in a residential area or apartment
building without concern for neighborhood.

5 Operation Modes

The operation mode can be easily switched to another by operating the mode
selection dial. The tool can efficiently provide a variety of operations by itself.
The advanced electronic control allows for an optimal screw/bolt tightening or
drilling operation for each application.

What is Electronic Pulse System?

Low Noise and Comfortable Operation

The electronic pulse system generates powerful tightening torque by rotating the brushless motor in regular and reverse directions at high
speed repeatedly via electronic control. Lower operating noise has been achieved by this system.

Generated Torque

For Wood Screws
Tightening torque can be
selected from 3-stages
for optimal tightening
operetion for the screw
size.

Time

Electronically controls the motor with pulse control and repeats
regular and reverse rotations at high speed.

Powerful and fast-pulsed torque is
generated.

Preventing Damage to Materials/Screws

Electronic Clutch Mode
(Rotation only)

For Small Screws
This mode is suitable for tightening a
thin, short screw carefully or tightening
a screw slowly and firmly to prevent
damage to the screw-head.
The motor automatically stops to
prevent over- tightening at the preset
value.
Allows for quieter screw tightening
without such a clutch sound as a
conventional mechanical clutch makes.

Regular Rotation

Reverse Rotation

The hammer and the anvil rotate.

The hammer rotates in reverse direction.

The hammer increases the rotation speed
and turns the anvil with strong force.

(Rotation + Pulse)

Tightening torque can be selected from 2-stages
according to the screw diameter.
Optimal tightening torque can prevent
over-tightening and damage to the screw-head.

Work efficiency is improved thanks to the brushless motor that reduces electrical
loss. Maintenance becomes easier because replacement of carbon brush is
no-required.

Electronic Switch for
Comfortable Operation
The electronic switch provides
smooth switch operation. Even in a
long time operation, finger fatigue is
reduced thanks to approx. half the
pulling force of Hitachi’s conventional
models. Furthermore, longer service
life has been achieved due to less
current load to the switch.

For Drilling Work
A precise balance of rotation
speed and torque allows for
quick drilling.

What is “self drilling
screw”?
A screw with a
drill-shaped end.
The screw is tightened
while drilling a hole into
a material like steel
plate.
