not properly centered and rotates durdch

Have the chuck ordered for my Makita cordless screwdriver as a supplement and am very disappointed: Despite several attempts, an intact wood drill sits seltenst just in food, therefore wobbles around. In addition, the thing can tighten by hand only, which significantly limits the grip in the chuck.
The only alternative that I have found for the cordless screwdriver, are universal drill with hexagonal base. This brings me well clear.
In summary: A diver who does not dive, dive nix! : O)

PS: If you know a good drill (here you get some for more than 30 Euro, unfortunately without reviews), can me please send a comment - I would be grateful for that!
