Yes, I should have mentioned that. Particularly for me the 6mm cutter squeals and breaks easily.
Another option is the 6mm single flute carbide cutters I keep going on about... they can potentially cause a problem as they are 'upcut' (spirals upwards) so could lift the surface of the MDF but try it and see. It's worked fine for me, plywood was ok with them too.
