Atlas Copco Gas Rock Drills

The Atlas Copco Cobra Combi is a self-contained gas-powered combined rock drill and paving breaker, built for utility, railroad, and remote-jobsite crews who need to drill anchor holes and break pavement without a compressor. One gas engine handles both jobs, anywhere the crew can reach.

Drill and Break on Gas

The Cobra Combi suits remote anchor-hole drilling, secondary breaking, and off-grid pavement work. For the dedicated gas breaker, see the Cobra PROe; for handheld air rock drills, Atlas Copco pneumatic rock drills. Browse all rock drills.
