1. End Mills cut rotationally in a horizontal, or lateral (side to side) direction whereas a drill bit only cuts straight down, vertically into the material. 2. Endmills are available in a wide variety of lengths, diameters, flutes and types, and are chosen according to the material they are cutting and the surface finish required for the project.

For example, ball mills use large media, normally 1/2" or larger, and run at a low (10-50) rpm. The other mills, such as sand, bead, and horizontal, use smaller media from 0.3mm to 2mm, but run at a very high rpm (roughly 800-1200). High speed dispersers with no media run even faster rpm (1200-1800).

Large hammer mills can reach up to 20-50 t/h depending on the expected granulometry (more fine, less capacity ; coarser, larger capacity). Materials having a size up to 60 mm can be grounded to ~1 mm, while, if the feed is already finer (10 mm), hammer mills can reach sizes less than 500 microns.

Running It Too Fast or Too Slow Can Impact Tool Life. Determining the right speeds and feeds for your tool and operation can be a complicated process, but understanding the ideal speed (RPM) is necessary before you start running your machine to ensure proper tool life. Running a tool too fast can cause suboptimal chip size or even catastrophic tool failure.
