*As of October 2016. Among 16-18kg(H65SB3)/18-20kg(H65SD3)demolition hammers made by leading power tool manufacturers. (Surveyed by Hitachi Koki)
- Higher demolition performance
The optimized hammer mechanism with a cylindrical striker delivers a high impact energy and efficient impact rate, resulting in higher demolition performance.

*2:Compared to the previous model H65SB2/H65SD2. Actual performance results will vary depending on operational conditions.
Due to the large heavyweight (cylindrical) striker, the chisel easily cuts into concrete, which makes users feel more comfortable during demolition work.
The user vibration protection (UVP) system reduces vibration to a tri-axial vibration value of 15.5m/s2(H65SB3) and 13.9m/s2(H65SD3) by combining the following vibration control features.
- Optimized Hammering Mechanism
secures sufficient air cushion and improves hammering movement, decreasing piston reaction force generated during hammering. This results in significant vibration reduction.
- Shock-absorbing Construction (H65SB3 only)
Two front dampers on the front cover mount reduce vibration from an accessory tool.
Hitachi’s original low vibration handle, which consists of the upper unit with spring and weight and the lower unit with hinge, reduces vibration and user fatigue, allowing for extended usage.
- 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.
Lock-on button allows continuous operation without holding the switch lever. It is positioned at a little distance from the switch lever in order to prevent interruptions caused by accidental contact with the button during continuous operation.
Large, easy to grip switch lever is ideal for intermittent operation where the tool is switched on and off repeatedly.
- Soft Grip Handle that Fits Comfortably in the Hand
Double-layered handles with hard and soft plastics offer more comfortable grip and improved handling.
- 360°Rotating Side Handle with Comfortable Soft Grip
The side handle is fitted with an elastomer grip that reduces transmission of vibration to the hand for less user fatigue.
- Universal Tool Retainer (H65SD3 only)
accepts 3 types of 28.5mm (1-1/8”) hex shank bits: standard hex, collarless retaining groove and air tool bits.
