What type of bit to use

[JAZZCNC]

I agree with you Silyyavski, a 2 flute cutter at 1/8 to a 1/4 would be a good starting point, but I've never been told to run something until it breaks and then decrease it by 5% until it doesn't.

No you won't be and shouldn't be told that because it's foolish and expensive way to go about learning.!! . . But don't worry about bits breaking they often just snap off and embed them selfs in the work or ping to the side. They don't shatter in all directions.

So many factors come into play but if you buy quality cutters from decent supplier they will offer you cutting parameters that you can use as base line. Then tweak to suit your machine.
If Machine is ridged then go with whats recommended but in general you may want to take whats recommended and Back off 30% to get a feel for how machine handles it. Then go up or down from there. This way you'll quickly find what your machine can cope with and not cost you fortune in snapped cutters.

Don't do what lots of people do and buy cheap cutters thinking it's ok for learning because it doesn't always make for good or enjoyable learning and can give a false reading of what the machine is really cpable off handling.
Quality cutters are completely different animal and can be pushed much harder than most realise, often harder than the machine can even handle.

You'll notice I'm not offering or recommending any feeds or speeds and for good reason.!! . . . For all I know You could have a chinese 3020 with Dc spindle that struggles to cut butter without burning up.? . . . . I don't know your machine strength, spindle power or the quality of cutter or grade of material etc. So dishing out cutting advise premerturely is pointless and potentially dangerous to your machine and wallet if not up to the task.

Buy decent cutters and use manufacturer cutting guide lines with good dose of common sense based on your knowledge of the machine and you shouldn't have too much trouble finding what can and can't be run at.
Yes you'll maybe break a cutter or two but you'll have fun doing it.!!
