That would be good, but until then, I purchased a rather complete "Snappy" set of such self-centering hinge screw bits (together with a lot of other snap-in drill bit holders, plug cutters, pilot hole countersinks with depth stop collars, and screw driving bits, all designed to be used with US standard 1/3" shank ball detent chucks. Certainly not as precise as Centrotec, but much less costly, quick to change and precise enough for most of my applications.
