I had just purchased a Dewalt Impact Driver, and I need a way to convert my chuck to accept sockets. I ran into my local Sears and grabbed this. I loved it so much I have since purchased two more as gifts for family members.
Good tool at a great price!
This is a must-have for anyone with a 1/4" impact, hand-driver, or any other tool that needs to adapt to a 1/4" drive socket. I pushed this bit to the max the other day, and it did not twist, break, or mar itself. So far, so good. I cannot say the same for other manufacturers I have use in the past. This bit was designed for REAL work. Buy it.
