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.

When the ball mill rotates at the critical speed the theoretical trajectory of the charge is such that it would fall outside the shell as centrifuging occur at this stage and the medium is carried around in a fixed position against the shell. The formula to calculate critical speed is given below. N c = /sqt(Dd) N c = critical speed of ...
