Rock Breakers for Sale

A hydraulic breaker is the single most demanding attachment your excavator carries — it puts more cyclic load on the boom, hydraulics, and quick hitch than anything else in the toolbox. Sizing the breaker correctly to the host machine is the difference between fast, predictable demolition and a string of expensive hydraulic and structural repairs. As a guide, the breaker’s working weight should sit between 7% and 14% of the carrier’s operating weight: a 280kg AWA breaker pairs cleanly with 5–12t machines, while a 580kg GORE V6 is built for the 16–30t class.

Every breaker on this page lists its impact energy (in joules), oil-flow window, working pressure, and the carrier tonnage it’s rated for. GORE breakers come with auto-lube, anti-blank-fire, and a 3-year warranty for contractors who need maximum uptime in rock and frozen ground. AWA breakers are the cost-effective choice for everyday demolition and trenching on 5–12t carriers. Spare wear parts (chisels, bushings, retainers) are stocked for both brands at our Saltsjö-Boo workshop.

How Big a Breaker Do I Need for My Excavator?

The 7–14% rule is the industry standard: a breaker should weigh roughly 7–14% of your excavator’s operating weight. For a 14-tonne machine that’s 1 000–2 000 kg, putting you in the GORE G450 (380 kg) for general work or the GORE V6 (580 kg) territory for heavier rock. Going too small means slow cycle times and stalling in hard rock; going too big puts dangerous loads on the boom and hitch.

What Oil Flow Does My Carrier Provide?

Breakers need a specific oil-flow window from the carrier’s hammer circuit. AWA breakers run on 40–80 L/min — typical of 5–12t mini and midi excavators. GORE G450 needs 60–100 L/min (8–16t machines). The GORE V6 wants 90–140 L/min, which is standard on 16–30t carriers. Your machine’s spec sheet will list the breaker-circuit flow; we cross-check this on every order.

FAQ

Frequently asked

Do I need auto-lube on my breaker?
For occasional use a manual grease point is fine. For daily demolition or quarry work auto-lube pays for itself within the first season — under-greased breakers fail bushings, retainers, and seals fast, and a single bushing job costs more than the auto-lube system. All GORE breakers come with auto-lube as standard.
Are these breakers compatible with quick hitches?
Yes. Every breaker on this page is supplied with a top bracket pre-fitted to your chosen hitch standard (S40 to S80). Switching between bucket and breaker takes under 10 seconds with a hydraulic quick hitch. If you’re running an older machine without a hitch we can supply a direct-pin bracket — call our team on +46 10 520 04 68.
What warranty do you offer on hydraulic breakers?
GORE breakers carry a 3-year warranty on the housing and hydraulic components, with chisels and wear parts excluded as consumables. AWA breakers carry a 2-year warranty on the same terms.
