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