Here are a few suggestions: The stepover should be between 1/3 and 1/10 of the tool diameter. Use a larger stepover, in the 1/5 to 1/3 range, for soft materials that cannot hold detail well. Use a smaller stepover, in the 1/5 to 1/10 range, for hard materials or materials that can hold significant detail like metal and jewelers wax.

FastCutting Carbide Ball End Mills. Variable spacing between the flutes reduces vibration, allowing these end mills to provide fast cuts, smooth finishes, and long tool life. Made of solid carbide, they are harder, stronger, and more wear resistant than highspeed steel and cobalt steel for the longest life and best finish on hard material.

Cobalt Steel Ball End Mills with Two Milling Ends. With better heat and wear resistance than highspeed steel, these cobalt steel end mills can run at higher speeds and provide better performance on hard material, such as iron, hardened steel, titanium, and tool steel. When one end wears out, turn the tool around for a sharp edge.

Ball End Mills (Ball Nose) Ball end mills, or ball nose end mills, are used for drilling shallow holes, slotting a channel where a flat bottom is not required or most commonly used to produce multidimensional contours in molds or dies. The design of ball end mills forms a hemispherical cutting action identical to the diameter of the tool.

1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.
