Demolition Hammer

H90SG

Features


  • An optimized hammering mechanism, shock-absorbing construction and vibration-absorbing handles.



Optimized Hammering Mechanism

  • Secures sufficient air cushion and improves hammering movement, decreasing piston reaction force generated
    during hammering. And vibrations are significantly reduced by making the piston and other parts lighter.


Shock-absorbing Construction
  • Front dampers (A) and (B) on the front cover mount reduce vibration from an accessory tool.


Vibration-absorbing Handles

  • Reduces vibration from the main unit by means of four handle dampers bent by the rotating holder(A).

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

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

  Improved Handing  

Soft grip handles for more comfort

  • Double-layered handles with hard and soft plastics offer more comfortable grip and improved handling.

Large switch lever for more control

  • Reduces operator fatigue even for long operation periods.
