HIKOKI 52mm (2-1/16") Rotary Hammers DH52MEY

Fastest drilling speed and highest demolition performance in its class even at voltage drop

The efficient brushless motor offers higher drilling performance even with an extension cord used.

Compatible with engine generators

Designed to be powered by engine generators as well, thanks to Our original compact and high efficiency inverter circuit.

Fastest^*1 drilling speed and highest^*1 demolition performance in its class

• The high efficiency brushless motor and the optimized hammering mechanism achieve the fastest drilling speed*1 and the highest demolition performance*1 in its class.

Our original, pendulum dynamic vibration absorber (Only for DH52MEY)

• reduces the vibration from concrete drilling or chiseling by moving a weight and a leaf spring in the opposite direction to the movement of the hammer.

Vibration-absorbing handle

provides high vibration-absorbing effect by employing both transatory and hinge units.

The internal double-insulation construction with a very sturdy aluminium die-cast body and a plastic internal stator holder

• makes the housing more rigid, significantly enhancing durability of the motor unit.

  
  

Control panel

• 

  1. Push-button, constant speed control with variable speed
  Due to the built-in electronic control circuit that can adjust the impact rate according to applications, four-step impact rates can be selected by the rotation speed selector switch.

One push action for quick bit mounting

• A bit can be mounted by simply inserting it into the tool holder.

  
  

Large change lever

• An up-sized mode change lever is located on the top of the tool body for easier handling.

  
  

Large trigger switch

• Upsized, easy-to-grip trigger switch for more control.

  
  

Continuous operation function (available for the Hammering Mode)

• keeps the tools running even after the trigger switch is released, making chiseling easier.
