Deburring, cleaning, and finishing on contoured metal, plastic, and composite surfaces often requires a tool that can reach into corners and adapt to irregular shapes without loading or losing its cutting action. The 3M Radial Bristle Brush K120 150x12x25.4mm BB-ZB Type C Curved addresses this with flexible ceramic abrasive bristles that conform to workpiece contours while providing a consistent 120-grit finish.

Who is it for
