George Vondriska demonstrates why you need to change the speed of your router based on the diameter of the router bit you are using for your woodworking projects. A WoodWorkers Guild of America (WWGOA) original video.

    Problem is this George, RPM and MPH don't compute if you don't know the math. It would be better to explain prm to rpm so 22k rpm dialed down to 16k rpm as an example.

    George references 125mph in the vid. Is that a hard fast rule to go by? I have a set of router bits, and not knowing better at the time, ran them too fast. Now a few the bits have clear burn marks on the bit. This indicates to me that the bit is damaged an no longer good. Lesson learned. Since then I've slowed down the speed, but didn't know if there was a good hard fast rule.


    Is it ok to use a cnc bit on your router? If not ... why?

    I understand the maths but don't get why it's "more dangerous" for the larger bit to be spinning so fast. What is the effect of the faster speed on the work piece and me?? I have a fixed speed router so don't know what to do!

    How does shank size affect router speed and bit diameter?

    I knew to use slower sppeds with larger bits but didnt understand why. Its nice that wwgoa can explain things in a simple way thats easy to understand and makes sense

    I really appreciate videos like this. In addition to the instruction, you provide simple explanations and examples. The "why" helps me to retain the information. Thanks!

    Just watched George Vondriska's video on router bit speed. Not having used a router in over thirty years and new to woodworking, do the newer routers all come with multi speed controls?
