I have 3 spiral router bits that are (supposed to be) made of carbide.
They have 8 cutters - on the end and along the body.
They do great flat bottoming and very clean cuts.
I have used 2 of them in my plunge router - and they work great.

Tonight I tried the 3rd one in my router table (same router, PC690) - and it
didn't work
It burned not cut - and I was working on pine.
To the touch the cutters feel sharp
The router is turning the right way
I did take the protective goop off of it first (actually long ago)

It is a 1/4" shank , and a 3/8" cutter

This is the first time I've used this particular bit

Is there something about spiral bits that they need to get plunged for them
to work correctly?
It doesn't make sense to me, but I thought I would bring this question to
the collective wisdom for some insight.

Thx
Matt
