How to use a tooling ball?Sep 25, 2017· Tooling balls are really useful when you need to set work up on a sine plate. All of a sudden, all your references surfaces are gone, and the edges have turned into corners, which are inaccurate to pick up. If you had the foresight to install a tooling ball at a known location, you now have a point defined in all three axes to work from. Dennis
