I’m cutting some Corian, which I never really use. I heard it making this not pleasant noise and noticed that when the tool descends into the stock sometimes, it’s pausing a fraction of a second before spinning again (that’s the best way I can describe it). It looks like it’s stopping rotation and dragging a tiny tiny way and that’s making the sound and appears to skip. I’m letting the job continue because it seems to be non-fatal, but has anybody seen this behavior?
Here’s a video and you can see when the tool touches down where it jumps.
