So I just recently started using FS wizard and Im a bit confused about the lead angle setting when using a non indexable endmill. I understand that idexable cutters have different lead angles but do standard endmills have a different lead angle than the helix angle. Any info on this would be great.

Hello,
Lead angle of a straight end mill is always 90 degrees.
I recommend leaving the default fields as-is unless you know they are different.
Regards.
