- Freud makes both regular and dado blades that have "shoulders" after each
- tooth. These shoulders are set just a tad lower than the teeth. One of
- their purposes is to limit how fast wood can feed into the blade. If
- the wood feeds in too fast, the shoulder hits the wood. The shoulder is
- smooth and doesn't cut, so the wood can't feed in any more - until the
- next tooth comes by and lets it go a tiny bit more.
-
- Anyway, Freud claims this will help reduce the "climbing" you describe
- happening on your RAS.
-
- I don't have a RAS. The Freud dado set I use on my tablesaw doesn't have
- these shoulders.
