Tools Vary Woodworking tools, from table saws to portable saws right down to tiny routers vary in rotational speeds from around 3,000 RPM (Revolutions Per Minute) up to 50,000 RPM.  If it is a direct drive motor, the arbor RPM and the blade RMP are the same, which is true of routers and many, but not all woodworking saws.  Some table saws are direct drive or have equal sized pulleys.  This is important if you want to know the “rim speed” or “linear tooth” speed of the blade.
