I bought a 6" and also a 12" (just in case) but only used the 6" hex chuck which was trimmed down a bit. thicker than a few toothpicks and couldn't hold a drill bit in his head. The included small hex key broke when tightened and neither drill bit could stay in place with the tiny screw in the top socket of the head. Bosch is usually good but this was rubbish. Any Bosch manager has not bothered to do the necessary routine quality checks on this made in china product, I hope this doesn't happen with future Bosch products.
