Metabo (Hitachi) H90SG

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.

• 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.
