Milling Finish: Complete Guide [ Tips, Techniques, and

The biggest challenge with ball nosed end mills of various kinds is slow nose speed. As you get closer to the tip, the diameter on the ball gets smaller and smaller, finally going to zero. As a result, the cutter must perform over a wide range of surface speeds and chip loads at different depths in the cut.

Ball End Mills

Ball end mills have a rounded nose and create a round-bottomed groove in milling tasks. Also known as ball-nose end mills, they are rotated against a workpiece to make round-bottomed slots and pockets or mill complex shapes without sharp corners. Each end mill has flutes on its cutting head that carry chips away from the workpiece to prevent

1/16" End Mills

For longer tool life and a better finish in general purpose milling applications, these solid carbide end mills are harder, stronger, and more wear resistant than high-speed steel and cobalt steel end mills. Their extreme hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the end mill from breaking. They have a ball end for milling rounded
