### Very basic milling question about depth of cut The

The max depth you should use in a slot cut is the diameter of the end mill so for a 1/4 OD end mill you can cut 1/4 deep at a time If you need to go deeper then make multiple passes The max axial depth of cut meaning the max amount of the end mill that is touching the work when doing profiling cuts is 1 1/2 the diameter of the end mill.
