Looks like it holds Bilz type tap holders. They come in 3 or 4 outer diameters, with numerous inner diameters to take standard tap shanks. There are torque limiting ones and solid ones.
It's unlikely to be an auto reverse of the sort that you use on a manual mill, as the CNC machine does the down feed / reverse / infeed with the holder allowing a little axial float to compensate for slight errors in the programmed pitch compared to the tap pitch.
