My brother ran electric to his garage. He wanted me to use my Bosch 11224 "bulldog" rotary hammer to drive thre ground stake 6 feet in the ground. I had my doubts but he instisted he saw it done. We chucked the 1/2" chuck into the sds holder on the rotary. The chuck had to be left all the way open. Grounding bar barely fit in it. I ,and the wife for that matter,were amazed that my bulldog wallked ever so slowly(about a 2 ft a minute for 1st 3 feet then a ft a minute for last 3 ft.) the grounding bar into the ground. It didn't "grunt" ,as woussko calls it, it groaned. We also used the "hammer" feature to chisel(using wood chiseld) out under the roof eave a channel ,in wood above the cinder blocks, for the pipe carrying the wire and to remove a few roots in the wire trench. We also drilled a hole in the mortar for the ground wire. While they do not "hit" as hard as the "24" series Hitachis,the bosch "bulldogs" are tough as nails!!!!
