Unlike other rock hammers that are just vertical mining hammers stuck onto a drill, the Roughneck was designed to turn any horizontal directional drill into a highly productive rock drilling machine. The Roughneck rock hammer is capable of drilling at rates up to 150-feet per hour with exceptional steering performance. When coupled with the universal HD high flow rock drill housing, the Roughneck expands the capabilities of a single pipe directional drill to encompass nearly every rock condition you may face in the field without changing out the housing. HammerHead® has a reputation for producing the most advanced pneumatic equipment for the underground construction industry and the Roughneck is no exception. Roughneck was born for directional drilling. Give us a call, and let us show you how hard it can rock.
