A 2mm single flute carbide tool in alu will be needing 30k+ rpm - these spindles are slow compared to some, even 5-6mm single flute will need 24k rpm.
Single flute work well as they are pretty strong and have a lot of chip-space in the flute.
When you get down to sub 1mm tools you need mega-rpm.
Don't forget these motors are sold as engraving spindles - the tools are sharp pointed and can take any rpm you have.Last edited by Davek0974; 30-03-2018 at 09:37 PM.
