Proper Router Bit Speed (How Fast Should It Spin?)

Knowing how fast your router bit should spin is one of the most important (and misunderstood) parts of using a router safely. In this video, I’ll walk you through what actually determines proper router bit speed — and how to avoid costly mistakes like burning, chatter, or worse.

We’ll cover:
Why RPM isn’t the full story
What rim speed means and why it matters
How bit diameter changes everything
Where to find reliable speed settings for your router

Whether you're using a trim router or a full-size plunge router, this is something every woodworker should understand.
