Cobalt Steel Ball End Mills with Two Milling Ends. With better heat and wear resistance than high-speed 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.

Dry Ball Milling. Dry milling is another alternative to produce graphene. Graphite layers can be shifted by ball milling a mixture of graphite and chemically inert water-soluble inorganic salts. The ensuing water washing and sonication of the milling products can result in the production of graphene powders.
