• The invention provides solution to the problem of workers injury as the grounding rods are installed depending upon the material encountered when hammered into the ground material.
• The invention's set of case-hardened flanges assists the grounding rod in cutting through rocks and dirt of the ground material as the grounding rod spins in the hammer drill.
• The invention's top uses a slotted drive shaft (SDS) end for a bit retention system.
• The invention comprises an attachment device such as a SDS-style slot for coupling the grounding rod to a hammer drill. Alternatively, a spline end can be used in place of the SDS end.
• The invention can comprise a pair of SDS-style slots, cut into the shaft member, for coupling to a hammer drill SD S-style.
