End milling cutters, also called end mills, have teeth on the end
as well as the periphery (figure 27 on the following page). The smaller end
milling cutters have shanks for chuck mounting or direct spindle mounting.
Larger end milling cutters (over 2 inches in diameter) are called shell end
milling cutters and are mounted on arbors like plain milling cutters. End
milling cutters are employed in the production of slots, keyways, recesses,
and tangs. They are also used for milling angles, shoulders, and the edges
of workpieces.
