When setting up to use a small 60 degree carbide Dove Tail End Mill, which dimensions on that End Mill do you use to figure your Spindle Speed and Feeds?
The largest part of the Dove Tail itself measures about 3/8". (or there abouts) The the Dove Tail then tapers down to much less.
Which of these two dimension is used to calculate my spindle-speeds and feed rates? Do traditional mathematical formulas apply with Dove Tail End Mills?
