Hydraulic Breaker vs Hydraulic Hammer: Is There a Difference?
Hydraulic breaker vs hydraulic hammer: the same excavator attachment under different names. See which tools really differ and the five figures to specify.
All buyer guides
Hydraulic breaker vs hydraulic hammer is a question about words, not machines. Both names describe the same excavator attachment: a hydraulically driven piston that strikes a steel chisel to break rock and concrete. Buyers, dealers and manufacturers use different names for it, and that causes missed quotes and mismatched searches. This guide sorts out the names, separates the tools that really are different, and lists what to specify whatever you call it. LICH builds 18 hydraulic breaker models for 1 t to 80 t carriers.
Hydraulic breaker vs hydraulic hammer: same tool, different names
A hydraulic breaker and a hydraulic hammer are one and the same: an attachment mounted on an excavator, backhoe loader or skid steer, powered by the carrier’s hydraulic circuit. Inside, oil drives a piston up and down; a nitrogen chamber adds force on the downstroke; the piston strikes the top of a chisel, and the chisel breaks the material. The names you will meet for the same attachment:
| Name you may see | Same as a hydraulic breaker? |
|---|---|
| Hydraulic hammer | Yes |
| Hydraulic breaker hammer / breaker hammer | Yes |
| Rock breaker | Yes, when mounted on an excavator |
| Hydraulic rock hammer | Yes |
| Excavator breaker / excavator hammer | Yes |
| Hoe ram | Yes |
When you compare a hydraulic breaker vs a hydraulic hammer in two quotations, compare the specifications, not the label. The same LICH model is the right answer under either name.
Tools that are actually different
- Handheld hydraulic breaker: a hand-operated tool powered by a separate hydraulic power pack. Same principle, but a one-person tool, not an excavator attachment.
- Pneumatic jackhammer: powered by compressed air from a compressor, not by hydraulic oil.
- Pedestal rock breaker system: a breaker on a fixed boom beside a crusher grizzly. The breaker itself is the same type of tool; the boom replaces the excavator.
- Pile hammer and drop hammer: tools that drive piles or drop a weight; they do not use a chisel.
- Nitrogen (gas-type) breaker: a hydraulic breaker that relies more on gas pressure. See our nitrogen breaker vs hydraulic breaker guide.
What to specify, whatever you call it
In any hydraulic breaker vs hydraulic hammer comparison, five figures decide whether a hydraulic breaker or hydraulic hammer fits your machine:
- Carrier weight: the excavator class the breaker is built for.
- Oil flow and working pressure: they must fall inside the carrier’s breaker-circuit output.
- Breaker weight: what the boom and arm will carry.
- Chisel diameter: sets the bushings, pins and spare tools.
- Impact energy and impact rate: how hard and how often it strikes.
All five are listed for every LC model in the hydraulic breaker specifications chart. Three examples across the range:
| Model | Carrier | Breaker weight | Chisel | Oil flow | Impact energy |
|---|---|---|---|---|---|
| LC-53 | 3–5 t | 166 kg | 53 mm | 20–50 L/min | 406 J |
| LC-140 | 20–25 t | 1,977 kg | 140 mm | 120–180 L/min | 6,485 J |
| LC-200 | 45–55 t | 6,388 kg | 200 mm | 260–340 L/min | 29,700 J |

Searching and asking for quotes
If you search only for “hydraulic hammer”, you may miss suppliers who list the same tool as a hydraulic breaker, and the other way round. When you send an inquiry, write the carrier make, model and weight, and the five figures above. That turns a naming question into a fitting check. Our matching guide walks through it step by step, and how a hydraulic breaker works explains the piston, valve and nitrogen chamber in detail.
Questions buyers ask
Is a hydraulic hammer stronger than a hydraulic breaker?
No. They are the same tool; strength depends on the model’s impact energy, not the name.
Is a rock breaker the same as a hydraulic breaker?
On an excavator, yes. “Rock breaker” can also mean a complete pedestal boom system at a crusher, which uses the same kind of breaker on a fixed boom.
Which name should I use in a purchase order?
Either works if the order lists the model and its specifications. LICH quotations name the LC model, body type, chisel diameter and hoses.
Whichever word you use, send us your carrier details and the material you break, and we will quote the matching LICH hydraulic breaker, also known as a hydraulic hammer.
