    Description

    12.7mm End Mill as shown.  These are new old stock from Siem Tools which is now Arch Cutting Tools.  These regrinds use PCD explained below.
    PCD – PolyCristalline Diamond
    The polycrystalline diamond is a synthetically produced diamond material which comes very close to the hardness of monocrystalline diamond (natural diamond). Its high level of hardness makes it possible to machine and withstand particularly abrasive materials. Tools with PCD cutting materials are therefore extremely well suited for machining lightweight construction materials like aluminium, magnesium and fibre-reinforced plastics. When circular milling with PCD-equipped tools, fewer radius corrections are required before the end of the tool life in comparison to solid carbide tools. This significantly increases the process security.
