Designed for heavy duty demolition work the Hitachi H90SG is fitted with a 28.5mm hex bit shank and features a 2000 watt motor which produces a massive 70 joules of impact energy. The optimised hammering mechanism secures sufficient air cushioning between the piston and striker which improves the hammering movement and decreases piston reaction force which is generated during hammering.
Another outstanding feature of the H90SG is the User Vibration Protection (UVP) system. This UVP system includes vibration absorbing handles. While the front of the tool has a shock-absorbing construction to help reduce vibration from the bit being used. Tool vibrations are also significantly reduced due to improved internal components.
Greater product durability comes from the Aluminium Housing Body (AHB). The internal double insulated construction is housed in a sturdy aluminium die-cast body for improved strength. At only 32kg for easier handling, increased user comfort comes from the soft grip double layered handles, while the large switch lever offers more control to help reduce user fatigue during long periods of use.
