Quick Advice Needed - F&S

Can anyone suggest a suitable F&S for a 20deg V-bit with a 0.2mm tip?

I will be cutting Walnut to make a photo using VCarve. Maximum depth is 2.5mm.

Thanks very much!

I just had a quick play and found it doesn't make a huge difference as long as it doesn't burn the wood nor break the bit.

I'm going to try 1,000mm/min and 22,000RPM
