Mint concentricity

It is sometimes very handy when in a SDS hammer drill a "normal" drill chuck can be easily attached to use (when disconnected Hammer function!) Wood or metal drill bits with smooth shank can; the often saves having to carry a second machine.

Although SDS-Plus holder must have some "game" type of construction, running this chuck absolutely centered. It can be clamped from 1.5mm up to 13mm drill, wherein the locking of a drill is easily and safely done only by hand. Even the release of the lock is possible without great effort.

"Surprised" Some reviewers about the fact that this keyless chuck must not be used in the "Hammer" operation. Actually, however, this is logical, because the mechanical stress would be much too large - and what else the SDS drill chuck should be developed ???
