I purchased a 45 degree insert blade bit from Amana (link below) but am confused as to the settings. It included a vetric .tool file which I booted up in VCarve with 18k/290/148 rpm/feed/plunge rates however on their website it suggests 18,000/40/20. Whereas my GWizard calculator is suggesting 8k rpms.

I confess I'm a little clueless about that portion of cnc routing, I'd normally just defaults or fool around until "well that seems okay" and forget about it but I'm new to v bit engraving and the bit looks delicate.
Where is a decent place to start? I'm cutting baltic birch plywood at about .1 depth.
Appreciate any advice.
