What is the max operating RPM?

Thank you for your question. Bosch does not have recommended speeds for the router bits. There are several woodworking sites that do have a chart with the common router speeds: Here is a list of common 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

Generally, with larger bits like this one, I would advise a lower spindle speed. 10,000 - 15,000 rpm should be OK This may be limited by your router's speed control as many have a lowest setting of ~ 12,000 rpm Don't try to take a full depth cut: use two or three passes to reach the full profile.
