I’d also start with shallow DoC and let your ears tell you if the cutter and machine are happy. Taking even just 1mm depth passes and slowly increasing depth of cut or the feed rate will let you hear when the machine gets unhappy. It’s quite easy to clog up or snap a cutter that small, suction or air blast to blow the chips out would also be your friend.

They recommend: (16,000 RPM): Chip Load: .002 to .004 Suggested Low End Feed Rate: 32 IPM Suggested High End Feed Rate: 64 IPM

Tolerance is very difficult to measure, but any letter in this position (third letter) will work in any toolholder, if the other letters and numbers are correct.The most common letters for tolerance are G and M.

But then I came across this which gives me a great deal of doubt: https://buildyourcnc.com/item/endmill-singleflute-upcut-!0625-1-flute

It seems 0.0005-0.0007 chip loads are recommended (e.g. from here: Origin/consistency of chipload recommendations - #15 by Julien) …

Also, I would take a recommendation for a chipload in aluminium that is double the one they recommend for MDF…with a grain of salt, let’s say.
