"I bought this Item but the SDS connection isnt a SDS connection. The Shaft is to Small and you cant connect it to your Power Tool with SDS connection. I Recommend take your Power Tool to the Shop and try the connection after bying it."
"After three trips to my local branch I still didn't manage to get an adaptor that fits an SDS drill. All three adaptors tried were faulty - two wouldn't go in to the chuck of the drill and the third wouldn't stay in. This is a pity really as the part is solidly machined . However, until the manufacturers sort out the quality issue I would steer clear of this accessory."
