Again, I suspect there just isn't enough room to go full speed.
Now for a math question (before I go to Google to help): I really like the quality of the ball nose cut on this copper. Can some one tell me the trig equation to find the diameter of the bit at a specified depth of .003"?
Thanks,

The math for it is....
Given,
W = width of the cut at the specified depth
D = Diameter of ball nose
z = depth of cut
W = sqrt[D - 4(D/2 - z)^2]
So if you used a 0.04 diameter bit at a depth of 0.003, then the width would be 0.021.
But you also need to take into consideration the thickness of the copper. If you take 50um copper clad board, then your effective cut width reduces to 0.013 (almost half).
