Stanley Hydraulic
Breaker Hammer 1'' x 41/4'' Steel

Hi-Line Part-Number: SNBR45150

Nothing equals the impact force of hydraulic breakers. With the best power-to-weight ratio, higher blow energy, and lower noise level than pneumatic breakers, Stanley hydraulic breakers are simply the best choice. The 70-lb. class breakers deliver roughly the same impact energy as most 90-lb. pneumatic breakers. Internal components are continually bathed in hydraulic oil, providing long tool life with minimal maintenance. Since the hydraulic system is totally enclosed, there is no tool exhaust or oil atomization.


  • No tool exhaust
  • Quieter operation than pneumatic tools allows for use in sensitive areas
  • Hydraulic oil provides continuous lubrication of internal parts for longer service life
  • Modular, re-buildable design platform improves serviceability
