Sounds as if what Freud did is eliminate the need for a precisely machined
face to mate to the carbide, if we can believe the "representative's" post.
Could be good, could be bad, but we know it doesn't cool anything but the
price of manufacture.

Well, I don't know what you're referring to, but all "adiabatic" means is
that there is no heat transfer involved.

Dave,

I apologize for any misinformation there has been some about the
reason for the gap in the carbide on your bit. It is correct that we
put the gap there purposefully. The primary reason for this is that it
makes the carbide seat more consistently. It also allows for the
different heat contraction/expansion rates between the carbide and the
steel body that occurs during and after the brazing process. Since
carbide is brazed only on the flat back side and not on the edges
there is not an issue of strength. This change will eventually take
place on all of our bits.

Eureka!!!!! I've finally done it!!!!! The worlds first liquid nitrogen
cooled router bits!!!!!!!!

why didn't you do it right and use liquid helium? g

hey! I bet it has to do with allowing them to grind the sides of the
teeth before brazing....
