people, the picture is wrong. This thing is HUGE, a serious piece of steel. It's made in Germany and comes in a cool yellow DeWalt case. I've only used it once to insert a 36 x 3/4" SDS Plus bit, but it worked great and the weight and build of the adapter left no doubt as to its durability. When buying locally, SDS Plus bits seem cheaper and being more affordable than SDS Max bits however if I know I will be using a lot of bits I will order the correct SDS Max bit and wait for it but it's nice to have the flexibility and access to cheaper SDS Plus bits FYI I run these on a Makita HR4013C which is an awesome beast (and like the DeWalt adapter there are a lot more in real life).
