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.

Introduction Ball milling is generally known as a method to mix, blend, shape and reduce particle sizes. It can also be used as a mechanical synthesis method to produce materials that are milled to extremely fine powders. Several factors, like milling temperature, type of mill, milling speed etc. need to be considered when using ball milling as a synthesis method.
