How deep can you cut with an end mill?

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. So, for a 1/4″ end mill doing an edge cut you can engage up to 3/16″ of its length max. This has to do with deflection of the end mill more than anything else.
