The feeds and speeds in the OP's post are way off for us but its a difficult balance between what your machine is able to achieve with regards to your tooling selection.

I have popped the lid off the drum of the cyclone that feeds the CNC and been met with a burst of warm, wet, air. When I look in and see chips instead of powder (Mdf excluded) Im happy.
Yup, I was way off base confused on the chip load.
