Ok, two weeks and lots of endmills I've finally get some work done with 2mm Carbide End Mills (uncoated). But the work process seems very slow, so I gues if I use 1mm endmill it will be extreme slow. Watching videos it seems other working way faster.

And I'm still not sure if these are good choice for what I need.

Can someone advise me where to buy good end mills for cutting and engraving 1mm sheets of brass, copper and silver in Europe?

Also what's the difference between carbide and 2 flute mills?
