HITACHI DH40MEY2 Rotary Hammer
HITACHI DH40MEY2 Description
Lightweight and Outstanding Drilling and Demolishing performance
Its lightweight design (0.7 kg lighter than the current model*1) allows for increased maneuverability and less user fatigue.
The high-efficiency brushless motor delivers speedy drilling and the highest demolishing performance in its classs*2.
New Low Vibration Mechanism and Low Vibration Handle
|
13% lower vibration than the current model*
The new dynamic vibration absorber and low vibration handle significantly reduce vibrations for less user fatigue and improved operability. Compared with HiKOKI DH40MEY. |

Reactive Force Control
|
When the tool bit is suddenly overburdened during operation, the slip clutch works or the built-in controller stops the motor output before the entire tool jerks. Depending on the operating conditions, the Reactive Force Control function may not work or provide the specified performance. Please make sure that the workpiece is placed and supported properly, and that the main unit is held firmly during operation. |
