For best results use these bits with 1800W routers.
It is possible to use 1100W routers but only for brief passes that are short in depth.
multiple pass operations require advance planning.
To avoid making a mistake that could render it impossible to finish the job, carefully consider the entire cutting sequence before you begin.
all large diameter bits such as these should be used with caution and on router tables equipped with a fence. When possible, reduce the RPM.
