Actually Gerhard, that is very similar to what will happen when using a full circle cutter.
On the first tooth, if you cut to full tooth depth, and depending how large the internal diameter is, adjacent teeth will get a partial cut at the same time. So after the first tooth is cut to full depth, the next tooth should be well on it's way to being finished.
I think I will be using something like a 24 tooth cutter, that will be able to be rotated by three teeth at a time, when the first three get worn. That way, the middle tooth will be doing most of the cutting and the tooth either side will be partial cutting, and depending on the internal size, other teeth might also start to be cut.
