Are you saying that the chippers teeth overlap one another?

Yes, just like on a normal carbide tooth dado set however there is a lot of
over lap rather than "just enough".



So that the chippers will always take out the groove, while the outside
blades are microadjusted for width?

Yes

Does that mean the adjustment takes place in the shaft through the center
of the dado set?


The flat center dial on the outer blade moves left or right. It is about
2.5" in diameter. When it is installed on the arbor the hub rests against
the chipper and holds the blade different distances fron the chipper.
