CNC End Mill Comparison Guide

Ball-Nose End Mills. Ball-nose end mills have a dome-shaped tip. These excel at high-detail contours like relief artwork or mold and die making, but have what is known as "scalloping." Since the tip of the end mill is round, having a perfectly flat surface is a challenging feat and will take many more passes than a simple fishtail to smooth ...

Very basic milling question about depth of cut

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 …
