Aarou, if you dig into the log with the bur at slow 5000 rpm speed, just see how it cuts. Keep increasing the speed until it stops cutting and starts loading up and not cutting. Every wood will be different. You will get the feel of it as you go. Usually when you purchase the bur it will show Max rpm. For the steel I woiuld say max would be about 8 to 10,000. The carbides about twice that.
