Now Meets Tough U.S. EPA1 Emission Regulations!

Freedom of Movement, Zero Setup Time!

Our Gas Powered Breakers/Drills:
  • Are Easy to Operate
  • Run without a Compressor
  • Hits harder than a 60 lb. air breaker
  • Hits twice as hard as an electric breaker

With no compressors, hoses or cables to set up, gas breakers are ideal for smaller jobs. They are indispensable for tasks that involve moving along a line, from position to position. Or for working in remote, inaccessible locations. And for many years, they have been a standard piece of equipment for emergency teams.

But the Cobra Combi is not only a self-contained breaker, it’s a powerful drill as well. It can sink holes to the depth of 6.5 feet, and drill up to 12 inches per minute in solid granite.

A Multi-Purpose Tool
With a range of 18 different tools, you can use the Cobra Combi for everything from cutting and breaking, to drilling, driving and compacting. So whether you need to just break a small patch of concrete, or split a rock, you can get the job finished with a gas-powered machine in the same time it takes just to set up a compressor and hoses.

You can use the multi-purpose Cobra Combi to:

  • Break Concrete
  • Cut Asphalt
  • Drill
  • Dig
  • Split Rocks
  • Drive Posts and Fences
  • Drive Rods and Spikes
  • Tamp and Compact Soil
  • Tamp Ballast/Ties
Breaking Concrete Cutting Asphalt Drilling Digging Splitting Rocks

The Atlas-Copco Cobra Combi is a successor to the earlier and well-known model Cobra 149 and the Pionjar Gas Drills. At the same time it is unique in its design since several improvements have been made to meet both environmental requirements from authorities as well as operators demand of ergonomic design and user comfort.

Cleaner emissions, lower vibrations, less noise
It is not only the design that is new on the Cobra Combi. Firstly, the noise level is lowered from 114 to 110 dB thanks to a new muffler and it is thereby fulfilling the European Noise Emission Directive (NED). Secondly, new vibration dampened handles reduces vibration levels from 8 to 5 m/s². Also, with a new carburetor and a catalytic converter, the emissions are cleaner and meet the tough US emission regulations, EPA1. Further, with a new choke control, new carburetor and user-friendly start instructions, Cobra Combi is easy to use. The new gas control gives the operator better control of the speed and enhance the precision when operating.
