Review on Simplify Your Routing with Whiteside Model UDFT9112 Spiral Template by Michael Boyce

This accessory delivers exceptionally smooth cuts. It is designed for a maximum speed of 18,000 rpm. I've had great results at this speed on desktop machines. I've tried using it in a manual router with less than satisfactory results. The aggressive cut it produces isn't very manageable. I've also found that running above 18,000 rpm causes rattling and poor trimming. When used as directed, this is an excellent tool.
