Weldon Flats
Our tooling is available with weldon flats, which are used in side lock holders to secure tooling. Learn about our two weldon flat options below.
Standard Weldon Flat vs. Advanced Performance Weldon Flat
Here at Fullerton, we have 2 types of Weldon Flats available - the Standard Weldon Flat and the Advanced Performance Weldon Flat. The Standard Flat (WF) and the Advanced Performance Weldon Flat (AF) are essentially the same, but the length of the Weldon Flat to the cutting 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 cause the tool to break.
