Note that some of the dovetail bits’ depths of cut overlap. For example:
No. 70-8 bit

This means all three bits are capable of routing boards

" [12,7mm] thick using
one of the following combinations: No. 80-8 and 140-8, No.75-8 and 140-8,
or No. 70-8 and 140-8.
The three bit combinations will produce slightly different-looking joints
because each dovetail bit produces a different size diameter of pin:
No.70-8

No.75-8

No.80-8

Do not attempt to rout dovetails at less than the minimum depth of
cut specified, as the bit can hit the guide fingers or guide bushing.
