The Tools dialog is used mainly to control the appearance of the Toolbox. It allows you to customize the set of tools for which icons are shown in the Toolbox, and the order in which the icons are arranged. Probably the most common use for it is to make the Color tools available directly from the Toolbox. You can also use the Tools dialog to select a tool by clicking on its symbol, but for this purpose you might as well just use the Toolbox.

Right-clicking inside the dialog produces the Tools menu, which gives you an alternative way of toggling visibility or restoring the defaults.
