some ppl just have that SDS drill bits lying around, along with other normal straight shank drill bits, but it is a pain having that "superior looking" SDS drill bit and not being able to use it...(no SDS chuck, or having a SDS chuck with a broken drill end stuck inside it, duh!)
so, my cheap fix is to take the sleeve of an anchor bolt (i use the nearest anchor bolt i found, a 5/16", about 1mm sleeve thickness), and wrap it around the base of the SDS drill bit...
i achieved that by inserting the bit inside the sleeve, with the bit base on the floor, and the sleeve's split end pointed upward, place a pair of pliers over the sleeve and knock it in with a hammer. be sure to align the "seam" of the sleeve along the long slot of the SDS bit, so that the 3-jaw chuck teeth (dogs) will have a firm clamp on the bit, and the bit will be fairly center. for drilling a hole in a brick wall to hang a picture, a 4" long 6mm drill bit is useful enough. i tried sleeve-fixing on a longer SDS drill bit, but it's still a little bit off center/wobbly.
the 3-jaw chuck takes 13mm drill bit or slightly larger, SDS+ drill bit is about 10mm wide, so it works. this fix will surely extend my time to decide if that expensive and heavier hammer drill that takes "superior looking" SDS drill bits is really necessary.
