3 Axis CNC router

Oh ok. Fair point. Put it this way. I'd rather use a cheap 6mm bit and have it snap when something happens, than trying to hold on to a router with a 10mm bit when it catches on something and doesn't snap. My vote is for the 6mm bit all day.

As for flute count, yes single flute would be best, but you can also go two or even three flutes. Three flutes have a thicker core so they'll be the sturdiest, but they will gum up the easiest. If you can strap an air line to the router and point it at the bit, then that will help immensely. Also with three flute you'll need to move quickly to keep your chip load the same. Too slow and you'll be rubbing, not cutting. Which leads to heat, which leads to gumming up.

Try stepping down in increments of 0.5mm at a time to start with.
