I have a compact Bosch Uneo cordless hammer drill. This has the SDS-Quick system, ie a chuck for use with a 6-hexagonal shank. A set of different drills for wood, metal and stone, although I have bought it, but I did not want to give up all my other drills, countersinks, hole cutters, flat wood drill, etc. That's why I was looking for a keyless. The small range often only up to 6mm, the next to 10mm. However, there may be short of some sinkers or Holzbohrer there already. So I was looking for a quick-to 13mm. However, the original from Bosch costs about 40 euros, and that was me then but for the "occasional use" bit too expensive. Then I'm on the chuck of profile drills, hear with 2 '13 mm, which costs just under half. Due to the positive review of "Schwerti" I have also ordered me and have to agree with him. It is a very well-made chuck. Although it looks because of its greater uptake in the small Uneo something unsightly, but one wants to win any beauty contests when drilling: :) Delivered it was with me in a neutral white box with no label or producer. The chuck is supplied in 2 parts, the actual chuck, and the 6-hexagonal shank with screw cap. In this, a screw is screwed, which can rotate out unfamiliar with the clockwise direction. Then you screw this from below in the chuck a. After you open the chuck completely, setting up of the screw and screw it now, again unusual, counter-clockwise firmly. The opening and closing works flawlessly and the drill used to keep very well. Of course, the drill used there have a little more game and "eggs easy" idle, but when drilling time becomes relative. It's finally not a fixed drilling head, and something else I did not expect it. So I am using the chuck is also very satisfied and would recommend it unreservedly.
