Due to the internal double-insulation construction with a plastic stator holder and an aluminium die-cast body which firmly holds the armature shaft, the durability of the motor and the tool body has remarkably improved.

• Overload durability: Comparison of the torques when the motors burn out, based on the durability index of the previous model taken as 100. (The values are for reference purposes. They vary according to conditions.)

  

• Soft and easy to grip for comfortable operation.

  

• causes the gears between the motor and drill bit to slip when an excessive load is suddenly applied, resulting in less reaction force.
