The 3M Yellow 3" Radial Bristle Disc (80 Grit) is an aggressive, flexible abrasive wheel used for heavy cleaning, deburring, and surface preparation without the need for messy polishing compounds. It features 3M's proprietary ceramic and aluminum oxide abrasive grains embedded directly into the flexible plastic bristles. As the bristles wear down during use, fresh abrasive mineral is continuously exposed to provide a consistent finish.
Key Product Features
  • Coarsest Available Grit: The yellow 80-grit variant serves as the most aggressive starting point in the 3M radial disc lineup, ideal for removing heavy oxides, rust, firescale, paint, and deep scratches.
  • Stackable Design: These single-ply discs are designed to be stacked together on a mandrel or tapered spindle—typically between 3 to 6 discs—to create the custom brush thickness required for your specific application.
  • Contour Conformity: Unlike rigid grinding wheels, the flexible bristles conform seamlessly to complex details, curved surfaces, and hard-to-reach areas without damaging the underlying base material.
  • Cool Running: The open bristle design generates minimal heat, reducing the risk of thermal damage, loading, or smearing on the workpiece.
