Hydraulic breakers
Hard-hitting power to get more done
We have the right tool for your need
BRK 40 - Lightweight, multi-purpose breakers
BRK 50 - Medium weight, multi-purpose breakers
A favorite with rental companies, BRK 55 breakers are the ideal choice for road building and maintenance applications. Whether it’s asphalt, brickwork, frozen soil, or concrete, the BRK 55 gives you reliable performance, especially when using a wide asphalt chisel on medium to hard asphalt. Can be used with both 8 gal/min and 5 gal/min power packs.
BRK 70 - Heavy-duty, multi-purpose breakers
BRK 95 - Super heavy-duty breakers
Handheld breakers don’t get much more powerful than this. With probably the highest impact energy in its weight class and an impact rate of 1,275 blows/min, in some situations, the BRK 95 can even replace small excavators with breaker attachments. Ideal for breaking heavy asphalt, reinforced concrete and foundations, these powerful machines are the rugged choice for utility construction, street main-tenance, repair of water and gas lines and general construction jobs.

Safety and operating instructions
HBP = High Back Pressure
Models with the designation HBP are designed to accept the higher hydraulic return pressure that can be seen on most skid steers and when using extra long hose lengths. HBP breakers can be operated from the PTO outlet of most skid steers.
