Maximun safe RPM

A 3" raised panel bit should be run at about 12,000 RPM typically the slowest speed on a variable speed router. Preferably an electronic variable speed so that it maintains the same speed under a load.

For future reference as suggested by Jesada

Up to 1" diameter, 24,000 rpm

This is about right

I have a Freud 1" rounding over bit which is 2-1/2" OD.

Info supplied with bit.

Absolutely NOT safe to run 3+ inch diameter router bits at full speed.

Suggested maximum cutting speeds from one manufacturer: to 1" - 24,000 RPM to 2" - 18,000 RPM to 2.5" - 16,000 RPM to 3.5" - 12,000 RPM

I can tell already that my pc 2 hp router isn't going to make the grade for that job. Got to get that 3.5 hp Milwaukee and see how that works.
