Stanley BR87320 Hydraulic Underwater Heavy Duty Breaker - 1-1/8 In. Shank (Includes Hose Whips & Couplers)

The BR87 is the largest breaker in Stanley Hydraulic Tools line up of underwater paving breakers. The BR87 is in the 90-lb. class of breakers and with its long piston stroke, is their hardest hitting hand held breaker. The feathering on/off valve controls speed and allows easier initial tool placement. Standard 11⁄8 in. x 6 in. hex chuck and latch retainer. Painted hi-visibility yellow.

Nothing equals the impact force of hydraulic-powered breakers. With the best power-to-weight ratio, higher blow energy, and a lower noise level than pneumatic breakers, hydraulic percussion tools are simply the best choice. 70-lb. class breakers, for instance, deliver roughly the same impact energy as most 90-lb. pneumatic breakers. Internal components are continually bathed in hydraulic oil, providing long-lasting performance with minimal maintenance requirements. And because the hydraulic system is totally enclosed, there’s no tool exhaust or oil atomization often found with gas-powered or pneumatic alternatives.

• Higher impact than comparably sized alternative platforms
• 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
• Handles system back pressures up to 250 psi / 17 bar
• Feathering ON/OFF valve to control speed and make initial tool placement easy

A general rule of thumb when sizing the appropriate breaker for your application is to use 10 pounds for each inch of material. A 40-pound breaker, for instance, is a good fit for 4-inch concrete. A 90-lb. breaker would be used to break 9-inch concrete.
