Router speed?

As many routers have variable speed, including your router, please help me to understand how to use variable speed.

There's a relationship between the bit size, the feed rate, the sharpness of the bit, depth of cut, and the hardness of the material you are cutting; there's not a simple answer to this question.

Generally speaking larger bits should spin slower than small bits, and deeper cuts and harder wood use slower speed rates. It's always a good idea to try a pass on a scrap of the same material to dial in your settings before moving on to your work.
