Forstner Bit RPM Guide placard

A simple placard to remind you of the correct speed when using a Forstner bit.  Included hard- and softwood settings.  

Two versions are included; one with screw mounting holes, one without.  Each placard is 155x135mm so they can print on small printers.  They are designed to print face down for better readability.
