Dynabrade DynaCut Extreme 5" 800 Grit Hook & Loop Sanding Disc uses premium P graded aluminum oxide abrasives to deliver a fast cut while maintaining a fine 800-grit finish, which helps dial in final surface prep before coatings. The disc is built on an extremely tough and tear resistant high performance 3 mil film backing, so it stays flat and stable under pressure, supporting consistent scratch patterns across the work area. A proprietary clog free coating is pigment free and provides a buildup resistant abrasive surface, so the disc sheds dust instead of loading, which helps maintain cutting speed over longer runs. The 5 inch size with an "Extreme" vacuum hole pattern and 25 holes directs sanding dust and sanding debris toward the center extraction holes where vacuum draw is the greatest, which improves on-tool dust collection performance during sanding.
This 5 inch aluminum oxide on film sanding disc uses a hook and loop attachment system, so it mates to hook and loop backing pads without adhesive, allowing the disc to be pressed on and pulled off quickly. That attachment style helps crews move between sanding steps by peeling off one 800 grit disc and installing another without waiting for glue to release or cure. The disc is designed with an "Extreme" vacuum hole pattern and 25 holes, which aligns with matching vacuum pads to direct sanding dust and sanding debris toward the center extraction holes, supporting efficient dust movement into the vacuum stream. The 3 mil film backing is described as extremely tough and tear resistant, so it stays intact as it is removed and reapplied to the pad, helping the hook and loop interface perform through repeated disc changes.
This Dynabrade DynaCut Extreme sanding disc sits in the Abrasive Discs product class and uses premium P graded aluminum oxide abrasives for fast cut and long life, which suits tasks where controlled stock removal and refined surface quality are both important. The 800 grit rating positions the disc for fine sanding and finishing stages, where the goal is to smooth prior scratches and prepare the surface for subsequent finishing steps. The extremely tough and tear resistant high performance 3 mil film backing keeps the disc stable under orbital or random orbit motion, supporting an even finish pattern across panels or parts. The proprietary clog free coating is pigment free and provides a buildup resistant abrasive surface, which is useful when sanding materials that tend to load discs, because the abrasive surface stays clearer for longer sanding passes.
The high performance 3 mil film backing generates the finest finishes and up to 4X the life of paper discs, which means each disc stays productive over more sanding cycles before it is worn out. That extended life reduces disc change frequency, which can streamline workflows where multiple similar parts are sanded in sequence. The "Extreme" vacuum hole pattern directs sanding dust and sanding debris to center extraction holes where vacuum draw is the greatest, so the vacuum can pull debris from directly under the pad and help maintain a clearer sanding path. A proprietary clog free coating that is pigment free and provides a buildup resistant abrasive surface keeps the abrasive grain more exposed, which supports consistent cutting action across the disc life. The hook and loop attachment system makes disc changes quick and easy, and discs can be saved for future use when not completely worn, allowing operators to swap to another grit and then return to a partially used 800 grit disc without losing it.
This Dynabrade DynaCut Extreme disc uses premium P graded aluminum oxide abrasives, which provide a fast cut and long life while maintaining consistent scratch quality on suitable materials.

The "Extreme" vacuum hole pattern with 25 holes directs sanding dust and sanding debris toward the center extraction holes where vacuum draw is the greatest, improving dust removal under the pad.
The proprietary clog free coating is pigment free and provides a buildup resistant abrasive surface, so dust releases more easily, supporting longer disc life and steadier cutting performance.
This 5 inch 800 grit disc uses a hook and loop attachment system, which allows quick disc changes and lets partially used discs be removed, saved, and later reused when needed.
The 800 grit aluminum oxide on film construction generates fine finishes suitable for later finishing steps, while the stable 3 mil film backing helps produce an even, consistent scratch pattern.
The Dynabrade DynaCut Extreme 5" 800 Grit Hook & Loop 25-Hole Aluminum Oxide on Film Sanding Disc combines premium P graded aluminum oxide grain, an extremely tough 3 mil film backing, and a proprietary clog free coating to support fine finishing tasks with fast cut and long life. The "Extreme" vacuum hole pattern and hook and loop attachment system work together to manage dust and simplify disc changes, helping crews keep sanding stations productive. For projects that demand a refined 800-grit finish with extended disc life, this Dynabrade abrasive disc aligns well with those workflow needs.
