Thank you for your question. The B-35081 1/2 in 15degree tilt socket adaptor is still a current product in Makita's inventory.
HD asked me to answer this; Barry is a VERY patient man if he's awaiting this response (bated breath?). Anyway, this adapter works with any brand socket (the sockets themselves are never "tilt sockets"). The benefit is the tilt of the adapter allows the socket to wobble. There are many times that the impact driver just can't be lined up perfectly w/ the socket. With this adapter, it's not a problem. The tilt takes care of it.
