This table can serve only as a guide, since wood was a living material. Within the same species of timber hardness and density vary.
Speed settings are approximate.
KEY: XX very good X good
Your router is equipped with constant speed cutting—as you load the router, the selected cutting speed
does not slow down during normal use. The electronic control governs the motor and gives you a
consistent finish to your work. Only under very heavy loading will the speed of the unit fall below the
governed speed.
To set the router speed (from 8,000 rpm to 24,000 rpm) rotate the speed control wheel shown in
Fig. 3. The higher the number the higher the speed. Consult the table below to help select the proper
speed for your application.
