The breaker models are designed to match Kubota's mini-excavator weight class according to hydraulic flow /pressure and lifting capacity.

THE PERFECT COMBINATION
Design to resist to all working conditions, the Kubota hydraulic breaker range has 6 models. They are perfect for indoor demolition and urban utility jobsites thanks to their weight/power ratio. They will bring you reliability and performance.
BREAKER CHOICE
SOLID DESIGN
The breakers of the KM series are solid body breakers, they do not have a casing which generates less vibration. There are also very few parts in movement, which will extend their life. Finally, their slender shape is perfect for use in trenches.
ENERGY RECOVERY
Increased operating efficiency and less vibrations will bring more performance and less fuel consumption for the mini excavator.
IMPACT RATE
To overcome soft materials such as concrete or asphalt, the impact rate is crucial (blows per minute) wherehas hard materials like granite that you can find mostly inside quarries needs impact energy. Our breakers with their very good weight/power ratio and their very high impact rate are therefore perfectly adapted to the urban environment of our mini excavators.
TOOL CHOICE
All working tools are manufactured to match Kubota breakers design, tolerances and performance. The unique designed impact surface of the working tool, is impeccably flat transferring the maximum energy transmission to the rock. In addition to this, if the impact surface is not perfectly flat, the energy will be unevenly distributed which may cause serious damage to the breaker.
WORKING TOOL DIAMETER
Our breakers have the largest tool diameter. It’s very important because the larger the tool, the larger the footprint will be, the performance will only be higher. It is a sign of a better efficiency between input hydraulic energy and output energy.

- TOOL CHOICE
TOOL CHOICE
- Moil point: For non-reinforced concrete. No torsion effect. Good penetration wedge effect in all directions (best in tools with small diameter)
- Chisel: For reinforced concrete. Strong torsion effect. Good penetration, optimum wedge effect in two directions
- Blunt tool: For steel rebar separation. Optimum energy transmission. No torsion effect, no penetration. No wedge effect.
