The version of Woltcraft chuck for Ixo IV but much too long. So only the photo on the product to be identified, separated by a Enkerbung rear of the hexagon pin sits in the cordless screwdriver. Thus, the chuck wobbles and looks totally on the Ixo from ludicrous. This gives a bonus point for the Familienerheiterung at the demonstration of this construction.
Since the Ixo only has a magnetic holder for bits, comes what must come: When you have drilled the hole ready and the machine restored to the backward motion, sliding the chuck out of the holder.
For cordless screwdrivers or drills with a deeper lining as it has the Bosch Ixo, like the Woltcraft chuck indeed be quite useful, but just not for the intended purpose of me. Fundamentally, the quality is fine. Clean design of metal makes the chuck a good impression, the drill is firmly and precisely in the feed. Therefore, the three stars.
