I recently purchased a set of Freud Super S508 Dado Blades. I was
under the impression that a couple of the blades that came in the set
we under 1/8" thick. I
I phoned Freud Canada and they told me that they don't measure the
tooth they measure the steel body.
Are Blades under 1/8 just not safe enough stability wise?
Do some manufacturers sell narrower blades?
I purchased the Forrest Dado King a few years ago. It has a the 1/8
inch chippers plus a couple that are under
1/8 to solve the problem. In addition, they supply a number of shims
to do some fine tuning.

According to the Freud site the SD500 series blades, I suppose yours falls
in that category, comes with (4) 1/8, (1) 3/32, and (1) 1/16 chippers. If
yours does not have those I would suspect that your set is short.
You should have shims also.

Mine too.
however,
http://www.freudtools.com/p-313-super-dado-sets.aspx
scroll to bottom of page for S508 set.
Web page has parts for S508 dado set to include 1 ea 3/32" chipper and
only 1 ea 1/16" chipper and 4 ea. 1/8" chippers.
Per the chart of chippers used, the dimension is the teeth cutting kerf.
For example: to cut a dado of 17/32 inches wide, takes the Left and Right
outside blades (1/4 inch together) plus one 1/8" chipper + the 3/32"
chipper + the 1/16" inch chipper.
Unless they sell a different product in Canada than USA, the OP is
correct, there should be two chippers that are less than 1/8" less tooth
kerf wide.

For a dado set you are only concerned with the total width of the dado
with various combinations of
the two outer blads and the chippers. When stacked on the motor arbor
the blade bodies are stacked
up against one another - thus the thickness of the blade bodies are
what determines the total width of
the dado. By stacking the blade bodies, shims can be placed between
the bodies t fine tune the
width by 0.01 inches.
As a previous poster mentioned, the carbide tips will overlap - the
overlap is also needed so that you can
place shims between the blades and still make a complete cut.
So get out your calipers and measure the bladed thicknesses.

It's a bit more complicated than that, though.
You are right in that for the chippers, it's the plate thickness and
not the width of the tip that should be considered.
For the two outer blades, however, it's the plate thickness plus the
outside tooth clearance (the amount that the teeth stick out past the
plate). It's not a big deal, but if you're measuring and adding up
plate thicknesses you'll always come up a bit shy of the actual cut.

Matsushita in 10" is commonly available in 3/32 kerf. in 9" you can
get 5/64 FWIW

What are you trying to do?
I know of no blade (for a full size saw, anyway) w/ a kerf < 1/8".
Dado set chippers may be thinner plate, but they're designed to run
between the two outer blades and the teeth may overlap. So their actual
width is probably 1/8" minimum, yes.
Some Dremel or other rotary tool attachment blades are very thin, otoh...
I don't know how thin one a kerf one of the little 3-5" trim saws blades
might ...

Except of course for those cases where you don't... :)

For OP, though, I had forgotten about these and the thinner blades that
are roughly 0.090" for a 10" iirc...

No, it's the THIN-RIM ...the plate dimension is for the center, not the
rim...they didn't provide the reduced rim plate dimension.

Are these thickness numbers bass-ackwards? I smell wood burning.
