Thank you for your question. Here is a guideline of Router Speeds 1” Diameter Cutter – 24,000 RPM 1 1/4” – 2” Diameter Cutter – 18,000 RPM 2 1/4" - 2 1/2” Diameter Cutter – 16,000 RPM 3” – 3 1/2” Diameter Cutter – 12,000 RPM
RPM concern is not so much an issue with these bits as would be the router it self to adiquately maintain efficient capacity to do the job of the actual work design required.
