55 lb. Rock Drill






rotary jackhammer

Our 55 lb. Rotary Jackhammers, also known as Rock Drills, utilize long drill steel with carbide tipped bits for drilling holes through concrete. The 55 lb. class drills are the ultimate in drilling performance and feature high impact as well as high rotation speed for maximum drilling speed. They utilize 1" hex hollow drill steel which allows the operator to blow the dust out of the hole when drilling by simply flipping a lever. We have drill steels shanks up to 4' long and carbide bits run from 1-1/2" to 2-1/2". Rotary Jackhammers require quite a bit of air so a towable compressor will be required. They come with the universal "Chicago style" 2 lug twist on air couplings.
