Impossible... to have top bearing on a chamfer bit.


This is the largest company in the US selling bits:

You will find several "stock" 45 degree bits on that page...

Thanks I emailed them. I guess what I'm looking for is called a "Top
Bearing" router bit. But online I still cannot find a stock 45 degree
