AYA Hydraulic Breaker — built for nasty rock and wet ground. Heavy one-piece housing and through-bolt core keep the hammer tight under side loads; long-life lower bushing centers the tool in boulder work. Nitrogen-assisted piston delivers consistent impact energy, while dual dampers cut shock back to the boom.
