Some time ago I used #302 to shallow v-carve brass (on a Shapeoko, but that is irrelevant), using
10.000RPM, 500mm/min feedrate (20ipm), 200mm/min plunge (8ipm), 0.2mm depth per pass (0.008")
and got half-decent results (well I got brass chips at least). Out of sheer curiosity, what cutting parameters will you be using with the 501 ?
