Description
Excavator Hydraulic Breaker for Concrete, Rock & Demolition
The Excavator Hydraulic Breaker from Construction Attachments is engineered for demanding concrete demolition, rock breaking, asphalt removal and construction applications. Available for compact, mid-size and large excavators, as well as applicable tractor loader backhoes, the CAL hydraulic breaker lineup offers multiple models to match different machine weight classes, hydraulic requirements and applications.
Also commonly called a hydraulic hammer, excavator hammer or rock breaker, this attachment converts the hydraulic power of the host machine into high-impact breaking force. As a result, operators can tackle concrete, rock, asphalt and other hard materials with a breaker properly matched to the excavator.

Excavator Hydraulic Breaker Models & Required GPM
Selecting the correct excavator hydraulic breaker starts with matching the breaker to the host machine’s hydraulic flow, operating pressure and machine weight.
Construction Attachments offers CAL hydraulic breakers ranging from compact excavator models to breakers designed for large excavators.
| Breaker Model | Required Oil Flow |
|---|---|
| CAL 225 | 3.76–6.6 GPM |
| CAL 500 | 7.0–16.0 GPM |
| CAL 650 | 9.25–18.49 GPM |
| CAL 850 | 10.57–22.1 GPM |
| CAL 1000 | 14.6–24.8 GPM |
| CAL 1200 | 15.9–26.4 GPM |
| CAL 2200 | 23.8–37.1 GPM |
| CAL 3200 | 34.4–68.7 GPM |
| CAL 4500 | 34.4–68.7 GPM |
| CAL 6000 | 14.6–73.9 GPM |
| CAL 8000 | 47.6–84.5 GPM |
| CAL 11000 | 68.7–105.7 GPM |
| CAL 18000 | 95.0–119.0 GPM |
Hydraulic flow is only one part of proper breaker selection. Machine weight, operating pressure, attachment weight, mounting configuration and application must also be considered.
Therefore, specify the exact make and model of your excavator when ordering.
Built for Concrete, Rock & Asphalt
A properly matched excavator hydraulic breaker provides powerful impact performance for demanding construction and demolition work.
Common applications include:
- Concrete demolition
- Rock breaking
- Asphalt removal
- Foundation demolition
- Trenching
- Road construction and repair
- Site preparation
- Quarry applications
- Excavation
- General demolition
Because multiple CAL models are available, the breaker can be more closely matched to the hydraulic capabilities and weight class of the host machine.
Auto Stop Anti-Blank-Fire Protection
The Auto Stop anti-blank-fire system is designed to help protect the breaker piston and through bolts.
Blank firing occurs when the breaker operates without proper contact between the tool and the material being broken. Therefore, reducing unnecessary blank firing helps protect critical components and can contribute to longer breaker service life.
Silence Kit & Host Machine Protection
The integrated silence kit helps reduce operating noise while also helping prevent dust and debris from entering the breaker housing.
In addition, a cushion damper helps protect the host machine from the demanding impact forces generated during breaking operations.
Together, these systems provide additional protection for both the hydraulic breaker and the excavator.
What’s Included With the Excavator Hydraulic Breaker?
Construction Attachments excavator breaker packages include:
- Base hydraulic breaker unit
- Mounting bracket
- Hydraulic hoses
- One breaker point of choice
- Tool kit
- Nitrogen pressure gauge
- Operator’s manual
The current live product page also confirms that excavator models come complete with the mounting bracket, hoses and one point of choice.
Important: Supplied hoses may require adaptation to the specific host machine. Additional hoses and couplers may be required depending on the excavator.
Hydraulic Breaker Chisels & Tool Options
Choosing the correct hydraulic breaker chisel or point helps match the breaker to the material and application.
Conical Point — Concrete
The conical point is designed for concrete breaking and general demolition where concentrated impact and penetration are required.
Moil Point — Rock
The moil point provides a pointed breaker tool for rock breaking and demanding demolition applications.
In-Line Chisel — Trenches & Slopes
The in-line chisel provides a defined cutting edge for trenching, slope work and directional breaking.
Cross-Cut Chisel — Trenches & Slopes
The cross-cut chisel provides a cross-oriented cutting edge for trenching, slope work and specialized breaking applications.
Blunt Tool — Quarry Applications
The blunt tool is designed for heavy breaking applications where impact and crushing force are preferred over penetration from a pointed tool.
Asphalt Cutter — Asphalt
The asphalt cutter uses a wide cutting edge designed for asphalt removal, pavement work, road construction and trenching applications.
When ordering a replacement hydraulic breaker chisel or tool, specify the chisel type, breaker model number and breaker serial number to ensure the correct tool is supplied.
Quick-Coupler & Pin-On Mounting Options
Models CAL 225 through CAL 2200 are available with a quick-coupler or pin-on hitch.
Models CAL 3200 through CAL 18000 come standard with pin-on hitches with pins and locking collars.
However, excavator mounting systems vary significantly by manufacturer and model. Therefore, provide your exact machine information when ordering.
Proper Hydraulic Setup Matters
Correct hydraulic setup is critical for hydraulic breaker performance and service life.
Before operating your excavator hydraulic breaker:
- Verify the excavator’s hydraulic GPM
- Confirm required operating pressure
- Verify the host machine weight class
- Confirm the correct mounting configuration
- Use properly sized hydraulic hoses and couplers
- Check hydraulic flow and pressure
- Avoid dry firing
- Use approved chisel paste
- Follow the operator’s manual
The breaker should always be properly matched and configured before operation.
Frequently Asked Questions
What is an excavator hydraulic breaker?
An excavator hydraulic breaker is a hydraulically powered attachment used to break concrete, rock, asphalt and other hard materials. It is also commonly called a hydraulic hammer, excavator hammer or rock breaker.
What GPM does an excavator hydraulic breaker require?
Required hydraulic flow depends on the breaker model. Construction Attachments offers CAL models ranging from approximately 3.76 GPM for smaller breakers up to 119 GPM for large excavator breakers.
Can an excavator hydraulic breaker break concrete?
Yes. Concrete demolition is one of the primary applications for hydraulic breakers. The breaker size and tool should be properly matched to the excavator and material.
Can a hydraulic hammer break rock?
Yes. Properly sized hydraulic breakers can be used for rock breaking when equipped with the appropriate breaker point or chisel.
What hydraulic breaker chisel should I use?
The correct breaker tool depends on the material and application. Conical points are suited for concrete, moil points for rock, in-line and cross-cut chisels for trenching and slope work, blunt tools for heavy breaking, and asphalt cutters for asphalt and pavement.
Does the excavator hydraulic breaker include a mounting bracket?
Applicable excavator breaker packages include the mounting bracket, hoses and one breaker point of choice.
How do I choose the correct hydraulic breaker?
Match the breaker to the excavator’s hydraulic GPM, operating pressure, machine weight and mounting configuration.
Specify the exact make and model of your host machine when ordering so the appropriate breaker can be selected.
