The Advanced Performance Weldon Flat (AF) and the Standard Weldon Flat (WF) are essentially
the same, but the length of the Weldon Flat to the cutting end of the tool is different. The AF is
measured from the flute washout to the flat. This guarantees that the flute or flute washout will
not be inside of the holder. If the flute or flute washout is inside the tool holder, the chips can
pack into the holder and can cause the tool to break.
