I bought a ground rod driver bit for a TE72 roto hammer the other day. Finally got to use it this morning. SWEET. Carrying that big Milwaukee up the ladder was the hardest part. I managed to get 7’4″ of rod in the dense clay ground in about 2 minutes before hitting rock. I’ll have to drive another rod to get past the inspection.
I have a slide type driver and of course the old standby sledge-o-matic, but this driver bit is going to send them into early retirement.
Kind of pricey at $70.00, but the time saved, as well as the reduced risk of injury means this puppy has a new home.
