A Steamroller Pipe is a type of hand pipe that is capable of delivering massive hits. These pipes function similar to a bong, but in a handheld fashion without water filtration. The shape and design of a Steamroller is a wide cylinder for increased volume, with a carb hole usually positioned at the front. The chamber of the Steamroller allows the user to fill it with smoke before clearing it with a single inhale, once releasing the carb.
