Dynabrade DynaCut Extreme 5 inch sanding disc uses premium P graded aluminum oxide abrasive on film, so it cuts aggressively while maintaining a consistent scratch pattern that supports even surface prep on wood, composites, or solid surface work. The 5 inch diameter with 25-hole "Extreme" vacuum pattern directs sanding dust and debris to the center extraction holes, helping the vacuum draw more effectively at the pad and keeping the work surface clearer during passes. A high performance 3 mil film backing provides an extremely tough and tear resistant base, so the disc resists edge tearing during corner work and stays flat on random orbital sanders. The 100 grit rating suits intermediate sanding where you need to remove machine marks while leaving a smooth surface ready for finer grits. The hook and loop attachment system allows quick disc changes between grits, supporting efficient step-sanding on jobsite or shop projects.
This DynaCut Extreme 5 inch 100 grit hook and loop 25-hole aluminum oxide on film sanding disc attaches to a compatible hook and loop backup pad, so installers can swap discs by peeling off one disc and pressing on the next without tools. The hook and loop system supports repeated on-and-off cycles, which helps when alternating between grits on the same pad during a multi-step sanding sequence. The 25-hole "Extreme" vacuum layout works with a matching vacuum backup pad design that pulls dust toward the center extraction zone, helping maintain abrasive cutting efficiency while the sander operates. The 3 mil film backing sits flat on the pad, supporting consistent contact across the disc and aiding even finish results across wide panels or smaller components.
This Dynabrade DynaCut Extreme 5 inch 100 grit hook and loop 25-hole sanding disc is suited to coated abrasive applications where a random orbital sander is used with dust extraction. The premium P graded aluminum oxide abrasive is configured for fast cut and long life, which supports extended sanding runs on cabinetry parts, furniture components, and shop fixtures before disc changeout becomes necessary. The 100 grit level helps transition from rougher shaping grits toward finer finishing grits, so it fits logically in the middle of a sanding sequence. The 3 mil film backing is extremely tough and tear resistant, letting the disc handle edge passes and inside corners without the typical paper-disc tearing. The proprietary clog free, pigment free coating provides a buildup resistant abrasive surface that is well suited to dust-producing substrates where loading can shorten disc life, so sanding stays more consistent.
The high performance 3 mil film backing generates some of the finest finishes and up to 4X the life of paper discs, so each disc can remain in service across more panels or parts before being discarded. This longer life reduces disc change frequency, which helps maintain workflow stability during production sanding or installation punch-list work. The film backing also helps the disc conform uniformly to the backup pad, supporting even pressure distribution and predictable scratch patterns across the workpiece. The "Extreme" vacuum hole pattern directs sanding dust and sanding debris to the center extraction holes where vacuum draw is the greatest, so dust is evacuated efficiently from under the pad during operation. Better dust removal helps the abrasive grains stay exposed rather than buried, which supports consistent cut rate and contributes to the extended service life described in the product data. The hook and loop system also lets technicians remove a disc that is not completely worn and save it for later, which helps align abrasive use with specific stages of a sanding system.
The Dynabrade DynaCut Extreme 5 inch 100 grit disc uses premium P graded aluminum oxide abrasives, providing fast cut and long life for routine sanding jobs on suitable materials.
The 3 mil film backing is extremely tough and tear resistant and generates some of the finest finishes, so the disc withstands demanding passes and produces smooth, consistent surfaces.
The Extreme 25-hole vacuum pattern directs sanding dust and sanding debris to center extraction holes where vacuum draw is greatest, helping keep the abrasive surface clearer while working.
The proprietary clog free, pigment free coating creates a buildup resistant abrasive surface, reducing loading so the disc maintains cutting efficiency longer during dusty operations.
The 100 grit Dynabrade DynaCut Extreme disc provides an intermediate cut level, allowing transition from heavier stock removal to smoother prep stages within a multi-step sanding process.
The hook and loop attachment system makes disc changes quick and easy, so installers can switch grits or reuse partially worn discs without tools or downtime.
The Dynabrade DynaCut Extreme 5 inch 100 grit hook and loop 25-hole aluminum oxide on film sanding disc combines premium P graded aluminum oxide, a 3 mil film backing, and an "Extreme" vacuum pattern to support efficient, repeatable sanding. The proprietary clog free, pigment free coating and hook and loop attachment system work together to extend disc life and simplify grit changes within a sanding sequence. For shops and installers looking to pair fast cut with controlled, fine finishes, this Dynabrade 91537 disc offers a balanced setup for regular use on compatible hook and loop vacuum pads.
