Maintenance-Free and Highly Efficient AC Brushless Motor

Longer Lifetime*1

The AC brushless motor offers a significantly extended product life cycle by eliminating trouble including armature burnout, layer short or commutator wear even in severe work environments.


No carbon brush replacement is required, which saves time and cost.

Stable Operation during Voltage Drop

The performance isn't affected as much by voltage drop from long extension cords on site. This vastly improves electrical efficiency.

The motor runs cooler and Very little performance degradation when used with an extension cord.

Excellent Grinding Performance with Less Fluctuation in Speed*1

The highly efficient AC brushless motor and electronic speed control maintains the speed and ensures work efficiency even when the load increases.

  1. Compared with HiKOKI brushed disc grinders.
  2. Use an extension cord no longer than 50m.

Ergonomic Design

  • 'Continue To Run' Function*

    Even after the motor has stopped due to overloading, it gets activated automatically if the load decreases within 1.5 seconds, so users do not have to restart the tool manually.

    'Continue To Run' Function
    • The motor may not automatically restart when the kick-back protection is activated or for other safety reasons. In that case, the tool needs to be turned off and on manually.
  • 3 Position Side Handle

    Fitting the side handle on top of the tool allows for easy operation in tight spaces.

Great Safety Features

  • Kickback Protection System

    Monitors a sudden drop in the motor rotation speed and stops the motor quickly to reduce the reaction force (kickback).

    Depending on operating conditions, the Kickback Protection System may not work or provide specified performance. Make sure that the workpiece is placed and supported properly, and that the main unit is held firmly during operation. Additionally, carefully read "KICKBACK AND RELATED WARNINGS" in the instruction manual.
  • Restart Protection

    The motor does not restart after the power has been temporarily cut off during operation to avoid accidents.

  • Soft Start

    Allows comfortable operation by reducing the reaction force on start up.

  • Electronic Brake

    Stops the wheel within seconds when the trigger is released, so users can get back to work quickly without wasting time waiting around for the wheel to slow down. The brake is also applied in case of unintentional disconnection of the power cord.

    Use only the wheel washer supplied.
  • Paddle Switch

    Stops the wheel when released. For even more safety, the paddle switch cannot be pulled unless the lock-off lever is pushed down.
