The drill itself fits. Maybe it's less durable than the others? This is the first foray into this type of bit. I'm a bit experienced, a bit more than a casual carpenter. I was definitely intrigued by the possibilities of this beat. The setup is a bit tedious. I have watched several videos on You Tube and I suggest the same to anyone who is new to this tool. Watch more than one video. In any case, be prepared to be patient with the setup. It took me a while to understand his nuances. Nevertheless, I can report that it works! Do not buy this to hand mill, you must have a table and a good table at the same time. The reason I gave one star for ease of use is because of the setup and to be clear, this is not for the more experienced.
