Cnc router wood "roughing bits" anyone used these before?

With a 2 flute bit, you should be cutting that at about 15-18m/min in one pass with that tool, at around 17,000 rpm. I cut plywood and particle board with a 3/8" compression all the time at 20m/min.

Bump the speed up to 15m/min and your bit will last at least 5x longer. And they won't break.

A roughing bit would need to be run at 20-25m/min to really take advantage of it, Running it too slow will dull it very quickly.
