End mills are designed with special attention to the cutting edge to reduce the risk of chipping, breaking, and wear. A corner radius is the defined curve at the junction of the cutting edge and end face that contributes to safe and effective plycutting. Large radii equate to smoother cuts while small curvatures allow for more precise work.

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.

Imagine the angle between the edge of the helix (the spiral flute) and the flat bottom of a standard endmill. A low helix endmill has an angle of 35 degrees or less whereas a high helix endmill has more than 35 degrees. A good roughing + finishing in one cutter compromise is a 38 degree helix angle.

Flutes Flutes are the easiest part of the end mill to recognize. These are the deep spiraled grooves in the tool that allow for chip formation and evacuation. Simply put, flutes are the part of the anatomy that allows the end mill to cut on its 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.

The rule of thumb is for every millimeter in diameter of a tool you get one flute, he said. For example, for tools with a ½" () diameter, the maximum flute number to be effective is 12 and for tools with a 1" () diameter the maximum flute number to be effective is 25. "For practicality that's a good way to do it," Clynch said.
