In the Loupe TV: What You Don’t Know About Weldon Flats
A Weldon Flat is a flat section that is ground onto the shank of an end mill, which is used to set screws in a tool holder to maximize rigidity in aggressive machining applications. They were originally designed specifically for high speed steel and cobalt tooling, but as high performance solid carbide end mills have been used more frequently, the design and usage of a Weldon Flat needs to be reconsidered. Join In The Loupe TV’s “Cutting Tool Counselor,” Don Grandt, as he explains how a Weldon Flat works and the considerations you should be making when selecting and using a Weldon Flat in your CNC milling applications.
