I love being able to drill and cut the tap at the same time but it broke when I first used #6. But I'm not sure if it was a weakness of the tool, maybe it was my fault. Be careful with them as they are fragile. Use a light, low-power drill/driver to get a better feel for control and drill angle. The convenience of a drill and a tap in one tool is enough to justify the risk of one breaking from time to time. I will buy again.
