Dynabrade DynaCut Extreme 5 inch sanding disc is a 5 inch abrasive disc that uses P graded aluminum oxide on film to cut fast and deliver a long working life, which helps installers move through sanding steps efficiently. The disc uses a high performance 3 mil film backing that is extremely tough and tear resistant, so it holds up under heavy use where paper discs would fail sooner. Its aluminum oxide abrasive generates fine finishes while maintaining cutting speed, which supports consistent surface prep across multiple parts. The disc is built as an abrasive disc in the Dynabrade line, so it fits directly into workflows that already rely on Dynabrade abrasives. As part of the abrasives category, it is suited for jobs that demand controlled material removal and smooth final surfaces. The product is sold in packs of 50, which supports production environments that run through discs regularly.
This Dynabrade DynaCut Extreme sanding disc uses a hook and loop attachment system, so it mounts to compatible hook and loop backup pads without tools by pressing the disc onto the pad. That attachment style allows the disc to be pulled off and repositioned easily, which is useful when aligning the 25 hole vacuum pattern to the pad holes. The 25 hole aluminum oxide on film sanding disc layout works with vacuum extraction systems by routing dust to the center extraction holes, supporting clear sightlines during sanding. Because the backing is a 3 mil film that is extremely tough and tear resistant, the disc stays flat and stable on the pad, which supports even contact and consistent cut during installation and use.
This product is an abrasive disc in the Dynabrade brand, so it fits naturally into abrasive workflows that call for 5 inch hook and loop sanding discs. Its 5 inch size matches common random orbital sander pads, which helps installers drop it into existing tools that accept hook and loop discs of that diameter. The 80 grit rating positions this disc for stock removal and intermediate sanding where material needs to be leveled while still preparing for finer grits. Because the coated abrasives are manufactured with premium P graded aluminum oxide, the disc supports repeatable sanding steps where consistent grit behavior is important for downstream finishing. The disc uses an "Extreme" vacuum hole pattern with 25 holes, so it works in dust extraction setups that rely on multiple ports feeding toward center extraction holes. The proprietary clog free coating is pigment free and provides a buildup resistant abrasive surface, which is useful in applications where dust loading would otherwise slow cutting or affect finish quality. As part of the abrasives category and abrasive discs product class at Wurth Baer Supply, this disc serves shops that run regular sanding operations on wood and similar materials.
The extremely tough and tear resistant high performance 3 mil film backing is central to how this Dynabrade 91536 sanding disc behaves under load, because the film keeps the abrasive layer supported when sanding edges, profiles, or wider surfaces. That backing generates the finest finishes while delivering up to 4X the life of paper discs, which has a direct impact on labor time spent stopping to change discs during a shift. With a longer running life, operators can stay on the tool and progress through sanding sequences faster. The proprietary clog free coating is pigment free and provides a buildup resistant abrasive surface, so dust does not embed as quickly into the grit and the disc maintains its cutting rate longer in use. That same coating characteristic helps keep the work surface cleaner, supporting smoother transitions between passes and between grits. The hook and loop attachment system works with this construction to let installers remove a disc that is not completely worn, store it, and then reuse it later where a partially used 80 grit is appropriate. Because the "Extreme" vacuum hole pattern directs sanding dust and sanding debris toward the center extraction holes where vacuum draw is greatest, the sanding zone stays clearer, which supports better visibility of the surface and more consistent contact across the 5 inch face.
This Dynabrade DynaCut Extreme disc uses premium P graded aluminum oxide abrasives, which provide fast cut with consistent grit behavior for predictable sanding results.
The disc uses an extremely tough, tear resistant 3 mil film backing, so it supports the abrasive under pressure and delivers fine finishes with extended service life compared to paper.
This Dynabrade sanding disc is 80 grit and 5 inches in diameter, which suits stock removal and intermediate sanding on tools designed for 5 inch hook and loop discs.
The disc features an "Extreme" vacuum hole pattern with 25 holes that direct sanding dust and debris to center extraction holes, improving dust removal at the strongest vacuum draw area.
The proprietary clog free coating is pigment free and buildup resistant, so it helps keep the abrasive surface cleaner and extends the cutting life of each disc.
This disc uses a hook and loop attachment system, so it presses onto compatible pads for quick changes and can be removed and saved when not completely worn.
The Dynabrade DynaCut Extreme 5 inch 80 grit hook and loop 25 hole aluminum oxide on film sanding disc offers premium P graded aluminum oxide, a 3 mil film backing, a clog free coating, and an "Extreme" vacuum hole pattern to support fast, controlled sanding. Sold in packs of 50 through Wurth Baer Supply, it fits production and shop environments that depend on predictable cut, extended disc life, and quick changes using hook and loop pads.
