The ball brush is Promax unique technology and is designed specifically for polishing and deburring the hole walls of parts.
Each tiny ball is full of grits, so the effect is more direct than abrasive filaments. However, the application for this kind of brush is limited. The wall of hole can’t have grooves because that might break the ball head.
