3M™ Hookit™ 600A Foam Disc 3M™ The 3M™ Hookit™ 600A foam disc is a high-quality abrasive designed for sanding and finishing applications, offering excellent flexibility and the ability to conform to contours and irregular surfaces. This disc is mounted on foam, which absorbs pressure variations, allowing for more uniform sanding and reducing the risk of creating marks or defects on the worked surface. Thanks to its Hookit™ attachment system, the disc can be easily attached and removed, simplifying disc changes and improving productivity. The 600A is ideal for fine finishing applications on painted surfaces, composites, and metals, ensuring a smooth surface ready for subsequent steps such as painting or polishing. Learn more
