Low on vibrations

Thanks to the Cobra's patented leaf spring design, the tool floats between the handles. Your hands remain in the same position while you break, and vibrations are kept to a minimum.

More productivity

Low vibrations and high impact energy mean you can use the tool for longer stretches of time.

A Cobra for every job

With 3 models and a vast range of working tools, there's a Cobra for every job. The Cobra PROe is the heavy-hitter of the family and suitable for breaking tough rock. The Cobra TTe is ideal for tie tamping. And the Cobra Combi is a drill and breaker in one.

Cobra PROe / PROi

The heavy-hitter

Cobra PROe

The impact energy of a pneumatic or hydraulic breaker, without the hoses, that' the Cobra PROe. Low hand and arm vibrations allow you to break for 3 hours at a go. Also available with fuel-injection (Cobra PROi).


  • Only 24kg for easy handling and transport
  • Smooth starting in all weather conditions, thanks to decompression valves
  • HAPS technology for lower hand and arm vibration levels
