3M 7100199261 Hookita 321U Disc 5 Inch 600 Grit

Product Description

The 3M 7100199261 is a Hookita 321U abrasive disc engineered for automotive paint preparation and body repair sanding. The disc combines a ceramic and aluminum oxide mineral blend designed to balance cut rate and finish quality across the full range of automotive sanding stages. At 5 inches in diameter and 600 grit, it targets fine surface prep and finish work. An anti-loading coating keeps the cutting surface clear of dust and debris, extending usable disc life. The Hookita hook-and-loop attachment system allows fast disc swaps without tools. Licensed trade painters and body technicians are the primary installers for this product.

This disc is suited for automotive collision repair shops and paint prep environments where consistent scratch pattern and disc longevity matter. The multi-hole pattern is engineered to align with most standard backup pads and supports dust extraction systems commonly used in professional body shop applications. It is available in a no-hole format as well. The 600 grit designation makes it appropriate for final sanding stages before sealer or primer application.
