My Craftsman 1/2" hand impact driver is over 40 years old. Not frequently used and when it is never has failed me. The adapter can take hex bits that are a shaft size up from the normal screwdriver bits.
Due to unknown forces and being in the right place at the right time, I just found this exact used model the other day on a garage sale 2 dollar table. Came home along with a craftsman ball pein.
