hello,
what is the difference between 10 and 14 degree dovetails (appart from the
angle), why choose one rather than the other?
I am asking because I just discovered that my dovetail bit (Woodcraft $5 on
sale bits) is 10 degree but that the only butterfly/spine bit (freud) is 14
degree....
do you know of any 10 degree butterfly/spine bit?

Aesthetics.
10 degrees works just as well as 14 on softwoods. 0 degrees
works fine -- aka box joint. Old ones seem to have failed at the
same rate as dovetails.

If you're using a dovetail jig, be aware that the depth of cut is usually
different for each angle ... this can be very important when cutting
half-blind dovetails!
10 degree bit: usually has a depth of cut of 7/16"
14 degree bit: depth of cut of is usually 5/8"
... be sure you consider this with regard to your stock thickness if you're
cutting half-blind dovetails.

...
The steeper angle is typically used in softer woods such as pine, the
more shallow in hard...
As for the availability question, no I don't have a source otomh...

The harder timbers have shallower pitches softer timbers have deeper
pitches
If your using a hardwood that is quite soft (many deciduous timbers are
softer than coniferous timbers its better to use a deeper pitch )
