Features: • Aluminium housing for greater durability on site. • Optimised hammer mechanism. • Low vibration handles with soft grip. • Large switch for ease of use. • Internal double insulation construction. • Available in 110V only. The H90SG provides 70J of impact energy, up to 27% more than the previous model (H90SE), ensuring that no job is too tough. A key feature of the breaker is its User Vibration Protection (UVP), it does this in 3 key areas. The hammering mechanism has been optimised to allow for a sufficient air cushion and also improves hammering movement, decreasing piston reaction force generated during hammering. Vibrations are significantly reduced by making the piston and other parts lighter as well. The construction of the machine has been designed to absorb shock through the tool using dampers. The handles themselves are also vibration absorbing.
