I really like this bit set. As many reviews say, they are very difficult to remove from the case. Removing them and enlarging the hole with a 1/2 bit really helps, but they are still very difficult to remove. I push them into the body as little as possible. I think if you use a metric nozzle closest to 1/2 inch you'd have better luck. Unfortunately I don't have one to try. However, using Beats is a pleasure. I haven't used them much yet, but they cut through everything like a hot knife through butter. These are the sharpest bits I've used including the Whiteside, Yonico and Ryobi (they were my first set). I have no experience of how long they stay sharp, but they are brand new. In addition, they are inexpensive. At around $16 for this kind of quality, it's hard to beat.
