8 Ways You're Killing Your End Mill - In The Loupe

While traditional roughing is occasionally necessary or optimal, it is generally inferior to High Efficiency Milling (HEM).HEM is a roughing technique that uses a lower Radial Depth of Cut (RDOC) and a higher Axial Depth of Cut (ADOC). This spreads wear evenly across the cutting edge, dissipates heat, and reduces the chance of tool failure.

The Anatomy of an End Mill - In The Loupe

The overall reach of an end mill, or length below shank (LBS), is a dimension that describes the necked length of reached tools.

The neck relief allows space for chip evacuation and prevents the shank from rubbing in deep- pocket milling applications.
