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 cast iron, hardened steel, titanium, and tool steel. When one end wears out, turn the tool around for a sharp edge.
Used Attrition Equipment. An attrition mill is essentially a mill that reduces materials by attrition rubbing. This can be with a single stationary plate and on rotating plate with tight gaps to reduce the particles down to size until they will pass through the mill. A double mill uses two counter rotating plates to achieve the required reduction.
