Sculpt Brush Select Tool
This brush is a little different from the other brushes because it does not move any points. This brush can be used to make point or polygon selections on objects to be deformed that don’t have a Sculpt tag assigned to them. This selection can then be evaluated by Sculpt brushes.
How this tool differs from the Live Selection tool: The Live Selection tool makes its selection perpendicular to the angle of view - whereas the Sculpt Brush Select tool internally uses a spherical space to whose borders the selection "expands". This makes it possible to include smaller regions that do not face in the direction of the camera. This tool also includes the sculpting Symmetry options, among others. However, this tool does not work in Use Edge mode.

If one of the first three options is enabled, the value will be applied to all Sculpt brushes (even if you use a preset). Example: You set the Wax brush’s Size value to 15 and you switch to the Erase brush. This brush will also have a Size value of 15 if the Link Size option is enabled.
If this option is enabled you will also be able to sculpt on the back side of a polygon (the cursor color will change to blue). The direction of the brush’s effect will remain unchanged for most brushes (the Pull brush, for example, will still pull in the direction of the surface Normals). The exceptions are the Scrape and Fill brushes.
If this option is enabled, the brush size will change accordingly when the Viewport is zoomed in or out to keep the visual size relative to the screen. If this option is disabled, the brush stroke will always have the same diameter no matter what the Viewport’s zoom factor is.
Here you can define how the brush preview should be displayed around the cursor:
