Atlas Copco Petrol Breaker Model Number: Cobra Combi In-use data available Cobra™ Combi is a great breaker aimed at lighter materials. Impact rate is higher and impact energy is lower compared to its brothers. And when you combine high impact rate and lower impact energy with rotation, you get a very powerful drill. This multi-purpose machine can drill up to 30 cm per minute in solid granite and to depths of up to two metres, thanks to its built-in airflushing device.
