End mills with PCD blades are currently still attracting little attention for use on modern machining equip-ments. The large range of standard end mills in solid carbide is probably the explanation for this. However, it is in this particular area that there are numerous arguments for using PCD end mills. Costly eroding to produce forms, such as those produced from graphite or large dimensioned integral components for aircraft production, require long tool life and reliability from the milling cutters used. It is in these cases that the enormous potential of PCD end mills can be demonstrated. The recognised advantage of long tool life for PCD cutting material can be directly applied.
