This SDS Plus ground rod driver set is designed to eliminate guesswork when installing electrical ground rods. By including two drivers, the set covers all common ground rod diameters—3/8″, 1/2″, 5/8″, and 3/4″—so there is no need to purchase multiple tools. Compatible with SDS Plus rotary hammer drills, these drivers convert hammer drill impact into straight, controlled driving force, making ground rod installation faster and easier than manual sledgehammer methods. The hollow cup design helps keep rods centered during impact, improving accuracy and reducing slippage. Constructed from solid steel, the tools are built for repeated use in electrical grounding, fencing, and outdoor construction work.
