What material are you cutting and what grade.? These spindles don't like large endmills or large drills, Not enough torque at the speeds required.
I pretty much exclusively cut Aluminium with mine and 8mm 3 flute works best. They will happily cut between 10-16K and will also drill at these speeds with drills up to 8mm thou I tend to turn up the RPM for drilling any way because of small drill size.

If you have Cam software that supports adaptive tool paths then use them because really suits these spindles with higher speeds n feeds and allows you to remove a good amount of material without stressing the spindle motor.

Regards the gumming up you are probably cutting to slow or even too shallow so your rubbing rather than cutting and overheating the tool. It's a common error people make when not used to cutting aluminum. Often They think it's the opposite and they are going too fast so slow it down or take even shallower cuts and it gets worse still.!!
That or you are trying to cut shitty 1050 series aluminum which is a nightmare to cut unless you cut through it in one go.?

It's a Similar thing with chatter.! . . don't slow it down, up the feed rate to push harder to increase tool pressure and it often goes away. Thou it's all a learning curve and each machine behaves slightly different and you tweak to suit.

Machines coming on nice..
