*1 As of May 2016. Among 5-7kg class hammers made by leading power tool manufactures (surveyed by Hitachi Koki).
*2 A comparison between the H45MEY and the previous model H45MRY. (The value may vary according to conditions.)

Brushless Motor
  • Long Lifetime, Maintenance-free
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. Besides, no carbon brush replacement is required.
  • Compact, Lightweight
Compact, Lightweight
  • Compatible with Engine Generators
Equipped with Hitachi's original, compact high efficiency inverter circuit, the demolition hammer works with an engine generator that doesn't have an on-board inverter. Compatible with Engine Generators
  • Stable Performance during Voltage Drops
The brushless motor runs cooler, and its performance isn't affected as much by voltage drop from long extension cords onsite. This vastly improves electrical efficiency. Stable Performance during Voltage Drops
Industry Leading Low Vibration
  • Hitachi's original, spring-type dynamic vibration absorber (on the H45MEY only)
Hitachi's original, spring-type dynamic vibration absorber with a weight and two springs move in the opposite direction to the vibration direction of the main body. This results in reduced vibration and improved operating efficiency.
coil
  • Low vibration handle (on both the H45ME and H45MEY)
Low Vibration Handle Hitachi's original vibration-absorbing mechanism with the Transatory unit (rubber dampers) and the hinge unit provides high vibration absorbing effect. This will help absorb and reduce vibrations to the user, making it more comfortable for prolonged periods of time.
*The UVP system includes the LVH mechanism.

High durability
  • The internal double-insulation construction with a very sturdy aluminium die-cast body and a plastic internal stator holder
Alminium housing body makes the housing more rigid, significantly enhancing durability of the motor unit.
Improved Handling
  • Push-button, constant speed control with variable speed
Control panel 1. Push-button, constant speed control with variable speed
The built-in electronic control circuit adjusts the impact rate according to applications, and the four-step impact rates can be selected by the impact rate selector switch.
