This might be off subject but...... Things have cooled down and I have taken the bit and looked at it. After cooling the bearing would turn but it was stiff, make that very stiff. I sprayed some bearing lub on it and it got a little better but I could feel something as I turned it and it was way to stiff to try and use.
I took the bearing off and this took a bit if effort, what struck me was the screw was still tight to the bearing. I took a plastic hammer and tapped it loose. Then things made more sence, the screw was turned in to the bearing, no washer or washer screw! With the screw out the bearing started turning like a new one! My guess is that someone assembled this one wrong. I was in a hurry so I never did check the bearing spin before using it.... after all it was new.
I don't know what damage the bearing may have taken during its short life but I think I will add a washer and see what happens durning some more routing.
So let's add another tip here: Always test spin the bearings before you use them (unless you're isolating them) and do it with new bits as well as the old ones.
