In many previous reviews was criticized that the second chuck is nowhere mentioned. This is at least in my version from July 2014 (no longer) way. On the back there is clearly doing it (even if only in English) and it is also a picture in which it can clearly be seen. Furthermore, the drill sizes stand on it, which unfortunately also missing in the Amazon description: 1.0 / 1.2 / 1.4 / 1.5 / 1.8 and according to my measurement Slide If the values also fairly accurate. For the actual product, unfortunately I can not say much ... it had just been unwrapped. If when using something to change in the 5 stars I'll update the review accordingly.
