This ground rod driver is made of steel, offering impact and rust resistance. It is a heavy-duty, one-piece tool designed for durability and long-term use. Compatible with all SDS-PLUS hammer drills (not compatible with SDS-MAX tools), it features a thick metal wall construction capable of withstanding high impact without damage. This tool eliminates the need for a sledgehammer and wood blocks when installing ground rods. It is suitable for standard steel T-posts, small signs, and shallow steel single posts used to support electrical outlets.
